It was developed during the 1980s as a high-powered, long-range cartridge for military snipers. Due to its use in the War in Afghanistan and the Iraq War, the cartridge has become widely available. The cartridge is named after the Finnish town of Lapua. The loaded.338 cartridge is 8.6 mm on in diameter (rim) and 93.5 mm on long. It can penetrate better-than-standard military body armor at ranges of up to 1000 m yd -1, and has a maximum effective range of about 1750 m yd -1 with C.I.P. conforming ammunition at sea level conditions. Muzzle velocity is dependent on barrel length, seating depth, and powder charge, and varies from 880 to 915 m/s in on for commercial loads with 16.2 g gr on bullets, which corresponds to about 6525 J ftlbf on of muzzle energy.

In reports, CoH Harrison mentions the environmental conditions at Musa Qala were perfect for long-range shooting: no wind, mild weather, and clear visibility."Super Sniper Kills Taliban 1.5 Miles Away" https://web.archive.org/web/20150514132925/http://news.sky.com/story/777941/super-sniper-kills-taliban-1-5-miles-away May 14, 2015 . Sky News, 3 May 2010. In addition to its military role, it is used by hunters and civilian long-range shooting enthusiasts. The.338 Lapua Magnum is capable of taking down any big game animals, though its suitability for some dangerous game (Cape buffalo, hippopotamus, white rhinoceros, and elephant) is arguable unless accompanied by a larger "backup" caliber: "There is a huge difference between calibers that will kill an elephant and those that can be relied upon to stop one."Robertson, K: The Perfect Shot, Safari Press, Long Beach, 1999. p. 50. In Namibia, the.338 Lapua Magnum in the past was legal for hunting Africa's big five game if the loads had at least 5400 J ftlbf 0 on muzzle energy. Since 2015, Namibia and other sub-Saharan countries generally require larger minimal bore diameters by law for big-five hunting.Hunting Laws& Rifle Importation http://www.napha-namibia.com/legal-information/hunting-laws-rifle-importation/ live https://web.archive.org/web/20150823035901/http://www.napha-namibia.com/legal-information/hunting-laws-rifle-importation/ 23 August 2015 5 July 2015 NAPHA - Namibia Professional Hunting Association History Initial development In 1983, Research Armament Industries (RAI) in the United States began development of a new, long-range sniper cartridge capable of firing a 16.2 g gr on, 0.338 in mm mid -diameter bullet at 914 m/s, that could lethally penetrate five layers of military body armor at 1000 m yd 0 on. After preliminary experiments, a .416 Rigby case necked down to take a 0.338 in mm on bullet was selected, since this diameter presents an optimum of sectional density and penetrating capability for practical spin-stabilized rifle bullets (bullets up to about 5 to 5.5 calibers in length).2011-07-19 Kneubuehl Beat What is the maximum length of a spin stabilized projectile? http://lutz-moeller-jagd.de/PDF/Kneubuehl.pdf Lutz-Moeller-Jagd.de 2023-02-11 https://web.archive.org/web/20110719055931/http://lutz-moeller-jagd.de/PDF/Kneubuehl.pdf 2011-07-19 The.416 Rigby is an English big-game cartridge designed in 1911 to accommodate 325 MPa (47,137 psi) pressures. One of the disadvantages of these old cartridge cases, which were intended for firing cordite charges instead of modern smokeless powder, is the thinness of the sidewall just forward of the web (the solid portion of a cartridge between the head and the bottom of the primer pocket). During ignition, the cartridge's base, just forward of the bolt face, is not supported. During the process, RAI employed Jim Bell and Brass Extrusion Labs Ltd. (B.E.L.L.) of Bensenville, Illinois, to make the .338/416 or 8.58×71 mm cartridge cases, Hornady produced bullets, and RAI built a sniper rifle under contract for the U.S. Navy. RAI found that the BELL cases did not fulfill the requirements, since they were modified low pressure.416 Rigby cases. Pressed by military deadlines, RAI looked for another case producer and contacted Lapua of Finland in 1984.The story of .338 Lapua Magnum, pt 1 https://www.lapua.com/the-story-of-338-lapua-magnum-pt-1/ 2021-02-19 2023-06-13 Lapua RAI was forced to drop out of the program due to financial difficulties. Subsequently, Lapua of Finland put this cartridge into limited production.Barnes, Frank C., Cartridges of the World 8th Edition, edited by M. L. McPherson, DBI Books, 1997, 0-87349-178-5. The .338/416 rifle program was later canceled when the contractors were unable to meet the project's velocity target of 914 m/s ft/s on for a 16.2 g gr on bullet, due to excessive pressures rupturing cartridge cases. Final development thumb|Left to right; .308 Winchester (7.62×51mm NATO), .300 Winchester Magnum (7.62×67 mm) and .338 Lapua Magnum (8.6×70 mm) cartridges showing their dimensional differences The .338 Lapua Magnum cartridge was developed as a joint venture between the Finnish rifle manufacturer SAKO and the British rifle manufacturer Accuracy International, along with the Finnish ammunition manufacturer Lapua, or more officially Nammo Lapua Oy, which since 1998 is part of the Nordic Ammunition Group (Nammo).From an American dream to a Finnish success story http://www.lapua.com/index.php?id=889 dead https://web.archive.org/web/20080430114500/http://www.lapua.com/index.php?id=889 2008-04-30 2009-05-16History of Lapua - About us - Nammo Lapua http://www.lapua.com/en/lapua/history-of-lapua.html dead https://web.archive.org/web/20180122071902/http://www.lapua.com/en/lapua/history-of-lapua.html 2018-01-22 22 February 2017 lapua.com Lapua opted to redesign the .338/416 cartridge. In the new case design, particular attention was directed toward thickening and metallurgically strengthening the case's web and sidewall immediately forward of the web. In modern solid head cases, the hardness of the brass is the major factor determining a case's pressure limit before undergoing plastic deformation. Lapua tackled this problem by creating a hardness distribution ranging from the head and web (hard) to the mouth (soft) as well as a strengthened (thicker) case web and sidewall immediately forward of the web. This resulted in a very pressure-resistant case, allowing it to operate at high pressure and come within 15 m/s (50 ft/s) of the original velocity goal. Lapua also designed a 16.2 g gr on .338 caliber lock base B408 full metal jacket bullet, modeled after its .30 caliber lock base bullet configuration. The result was the .338 Lapua Magnum cartridge which was registered with C.I.P. (Commission Internationale Permanente pour l'Epreuve des Armes à Feu Portatives) in 1989. With the procurement by the Dutch Army, the cartridge became NATO codified. The .338 Lapua Magnum fills the gap between weapons chambered for standard military rounds such as the 7.62×51mm NATO and large, heavy rifles firing the .50 BMG cartridge.Cartridges for Long http://www.quarryhs.co.uk/Long%20Range%20Sniping.htm live https://web.archive.org/web/20160527062842/http://www.quarryhs.co.uk/Long%20Range%20Sniping.htm 27 May 2016 22 February 2017 quarryhs.co.uk It also offers an acceptable amount of barrel wear, which is important to military snipers who tend to fire thousands of rounds a year in practice. This was achieved by coupling a sensible case volume (7.40 ml) to bore area (56.86 mm2/0.5686 cm2) ratio (13.01 Oratio) with ample space for loading relatively long slender projectiles that can provide good aerodynamic efficiency and external ballistic performance for the projectile diameter.The Finnish Army found out during a test/trials program and seven years of service that the barrels of their Sako TRG-42 sniper rifles lasted 7,000 to 8,000 rounds with Lapua lock base B408 factory ammunition before showing impermissible accuracy decay. The Finnish Army's consistent accuracy requirement for these rifles is less than one MOA at 1,000 m. If this requirement is not met the TRG-42 gets a new barrel. This is normal practice for active high-performance precision rifle operators who regard barrels as expendable items. The continuous use of very powerful handloads (which results in higher muzzle velocities) results in much quicker throat erosion reducing the TRG-42 barrel's accuracy life to 1,500 to 2,000 rounds. Like every other comparable large magnum rifle cartridge, the .338 Lapua Magnum presents a stout recoil.RECOIL http://www.accuratereloading.com/recoil.html live https://web.archive.org/web/20161027205130/http://www.accuratereloading.com/recoil.html 27 October 2016 22 February 2017 accuratereloading.com An appropriate fitting stock and an effective muzzle brake helps to reduce recoil-induced problems, enabling the operator to fire more rounds before getting too uncomfortable to shoot accurately. Good factory loads, multiple projectile weights and factory special application ammunition are all available.In 1990, the US military Adjutant General's Office issued a legal opinion holding that the Sierra MatchKing bullet (and similar bullets of other manufacturers), despite being a hollow point design, is not designed specifically to cause greater damage or suffering in a human target, and in fact normally does not create a wound readily distinguishable from wounds caused by conventional full metal jacket bullets, and is therefore in their opinion legal under the Hague Convention for use in war.Sniper Use of Open-Tip Ammunition http://www.thegunzone.com/opentip-ammo.html TheGunZone https://web.archive.org/web/20070427083045/http://www.thegunzone.com/opentip-ammo.html 27 April 2007 Due to its growing civilian popularity, several high-quality tactical and match (semi) custom bolt actions designed for the .338 Lapua Magnum are becoming available.

Remington announced that the MSR had won on 8 March, and it was publicly confirmed on 9 March.

Remington Defense would produce the Mk 21 sniper rifles and utilized two other companies for other system components, with Barnes Bullets for ammunition and Advanced Armament Corporation for muzzle brakes and suppressors; all three companies are subsidiaries of Remington Outdoor Company. However, it was then decided that the Mk 21 did not conform to SOCOM requirements, and the program was re-competed with the Barrett MRAD selected in 2019 as the Mk 22 Advanced Sniper Rifle solution.https://taskandpurpose.com/military-tech/barrett-mrad-military-sniper-rifle This is the US military's next sniper rifle of choice 24 February 2020 The US military opted to use 7.62×51mm NATO, .300 Norma Magnum and instead of the .338 Lapua Magnum the .338 Norma Magnum chambering in their Mk 22 rifles, which have a field-convertible barrel/chambering switch capability. Cartridge dimensions Extremely thick-walled brass results in a 7.40 ml (114 grains H2O) cartridge case capacity for the .338 Lapua Magnum. The exterior shape of the case was designed to promote reliable feeding and extraction in bolt action, semi-automatic, and automatic firearms alike, under extreme conditions. 400 px .338 Lapua Magnum maximum C.I.P. cartridge dimensions. All sizes in millimeters (mm). Americans define the shoulder angle at alpha/2 ≈ 20 degrees. The common rifling twist rate for this cartridge is 254 mm (1 in 10 in), 6 grooves, Ø lands = 8.38 mm, Ø grooves = 8.58 mm, land width = 2.79 mm and the primer type is large rifle magnum. According to the official C.I.P. (Commission Internationale Permanente pour l'Epreuve des Armes à Feu Portatives) decisions and tables edition 2007 the .338 Lapua Magnum case can handle up to 420.00 MPa psi on Pmax piezo pressure. This prevails over the C.I.P. decisions and tables edition 2003, that rated the .338 Lapua Magnum at 470.00 MPa psi on Pmax maximum piezo pressure.C.I.P.

In C.I.P. regulated countries every rifle cartridge combo has to be proofed at 125% of the prevailing maximum C.I.P. pressure to certify for sale to consumers. This means that .338 Lapua Magnum chambered arms in C.I.P. regulated countries are 2013 y proof tested at 525.00 MPa psi on PE piezo pressure. Lapua has been ambivalent on the maximum piezo pressure of this cartridge. In the article "From an American dream to a Finnish success story" by Janne Pohjoispää,From an American dream to a Finnish success story http://www.lapua.com/index.php?id=889 Janne Pohjoispää Lapua https://web.archive.org/web/20101204220859/http://www.lapua.com/index.php?id=889 4 December 2010 Lapua propagates the C.I.P. 2007 ruling of 420.00 MPa psi on maximum piezo pressure. To further complicate matters the mentioned 56,000 CUP C.I.P. copper crusher pressure translates to around 447.50 MPa psi on C.I.P. piezo pressure according to a study on the conversion from CUP to PSI for rifle cartridges by Denton Bramwell.Correlating PSI and CUP, a study done that shows a high correlation between CUP and PSI for rifle cartridges by Denton Bramwell https://web.archive.org/web/20070820110217/http://www.shootingsoftware.com/ftp/psicuparticle2.pdf 2007-08-20 . The C.I.P. 2003 ruling of 470.00 MPa psi on piezo pressure is corroborated by Lapua Australia in the "History and development of the .338 Lapua Magnum" article by Alan C. Paulson.History and development of the .338 Lapua Magnum 19 May 2016 http://elitehuntsman.com/history-development-338-lapua-magnum/ live https://web.archive.org/web/20180903215358/http://elitehuntsman.com/history-development-338-lapua-magnum/ 2018-09-03 2018-09-03 A reverse engineering simulation with QuickLOAD internal ballistic software predicted that Lapua load their factory .338 Lapua Magnum ammunition at about 420.00 MPa psi on piezo pressure, as Paulson asserts in his article. The large bolt face combined with the maximum pressure means that the .338 Lapua Magnum is normally only chambered in rifles that are capable of handling such large high-pressure cartridges, and thus high bolt thrust, safely. Chambering such powerful super magnum cartridges in rifles intended for normal magnum rifle cartridges and using high-pressure loads can cause serious or fatal injury to the shooter and bystanders. The American .338-378 Weatherby Magnum cartridge introduced in 1998 and the American .338 Remington Ultra Magnum (.338 RUM) cartridge introduced in 2000 are probably the closest ballistics-wise to the .338 Lapua Magnum commercially available 2007 y. The .338-378 Weatherby Magnum is, however, a belted cartridge and the .338 Remington Ultra Magnum is a rebated rim cartridge. The American SAAMI (Sporting Arms and Ammunition Manufacturers' Institute) has no normal voluntary guidelines for the .338 Lapua Magnum. On 14 January 2013 it opted to use the metric C.I.P. rulings and add some dimensions that have no C.I.P. analog.https://saami.org/wp-content/uploads/2019/02/ANSI-SAAMI-Z299.4-CFR-Approved-2015-12-14-Posting-Copy.pdf SAAMI Maximum Cartridge / Minimum Chamber drawing (METRIC) 338 Lapua Magnum, page 116 13 August 2019 21 March 2021 https://web.archive.org/web/20210321185522/https://saami.org/wp-content/uploads/2019/02/ANSI-SAAMI-Z299.4-CFR-Approved-2015-12-14-Posting-Copy.pdf dead Supersonic range performance of the .338 Lapua Magnum Performance with C.I.P. conforming cartridges For a typical .338 Lapua Magnum high-end factory military sniper rifle like the Sako TRG-42 with a 690 mm 1 on long 305 mm (1 in 12 inch) rifling twist rate barrel at sea level, 1500 m yd 0 on is considered to be the maximum shooting distance for man-sized targets. When using standard Lapua military 16.2 g (250 gr) loads it has a supersonic range of 1500 m yd 0 on under warm summer conditions at a muzzle velocity of 915 m/s on. However, to be able to maintain 80 to 90% hit probability on non-moving 45 x 90 cm in 1 on reactive army targets, this maximum shooting distance has to be reduced to 1300 m yd 0 at freezing point conditions or 1100 m yd 0 on in Arctic winter conditions, when the muzzle velocity may drop to 880 m/s ft/s 0 on—i.e. only during optimal warm summer conditions the 1500 m yd 0 on maximum shooting distance is realistically achievable.Weapon Employment Zone (WEZ) Analysis of the Optimized 300 Winchester Magnum vs 338 Lapua Magnum With Various Ammunition Types by Bryan Litz, Applied Ballistics LLC http://www.appliedballisticsllc.com/Articles/ABDOC116_2_300_338_Rev1.pdf dead https://web.archive.org/web/20150923172716/http://www.appliedballisticsllc.com/Articles/ABDOC116_2_300_338_Rev1.pdf 2015-09-23 2014-04-02Probabalistic Weapon Employment Zone (WEZ) Analysis A Conceptual Overview by Bryan Litz http://www.appliedballisticsllc.com/Articles/ABDOC115_ProbabalisticWEZ.pdf dead https://web.archive.org/web/20150923172715/http://www.appliedballisticsllc.com/Articles/ABDOC115_ProbabalisticWEZ.pdf 2015-09-23 2014-04-02 Loaded with more aerodynamic very-low-drag bullets such as the traditionally lead-cored 19.44 g (300 gr) Lapua Scenar GB528 VLD bullet (G1 BC = 0.736) or the Lost River Ballistics J40 .338 17.5 gram (270 gr) CNC manufactured mono-metal bullet (G1 BC = 0.871) the long-range performance and supersonic range of .338 Lapua Magnum rifles can be improved. These longer very-low-drag bullets require a 254 mm (1 in 10 inch) twist rate to stabilize them. Due to the lower practically possible muzzle velocities for a relative heavy bullet like the 19.44 g (300 gr) Lapua Scenar GB528 VLD bullet it gains about 104 m yd 0 on extra supersonic range under International Standard Atmosphere sea level conditions (air density ρ = 1.225 kg/m3) at a muzzle velocity of 837 m/s (2750 ft/s) when compared to the standard 16.2 g (250 gr) Lapua Scenar GB488 VLD at a muzzle velocity of 915 m/s (3002 ft/s). For significant supersonic range improvement, the aerodynamic efficiency of the employed bullets has to be significantly improved without sacrificing a lot of practically achievable muzzle velocity - meaning that besides the coefficient of drag of the projectile weight is also an important parameter for its actual downrange flight behavior. The .338 17.5 gram (270 gr) Lost River Ballistic Technologies J40 match bullet made out of a copper-nickel alloy is one of the most aerodynamic .338 calibre bullets available. It has an 1800 m yd -1 on supersonic range under optimal warm summer conditions at a muzzle velocity of 869 m/s on. This makes engaging static targets up to 1800 m yd -1 on feasible. + .338 Lapua Magnum ballistic comparison with other long-range sniper cartridges Cartridge Bullet weight gr (g) Muzzle velocity ft/s (m/s) Muzzle energy ft·lbf (J) .338 Lapua Magnum (8.6×70mm) 250 (16.2) 2,970 (905.2) 4,893 (6,634.0)Lapua product brochure .338 Lapua Magnum ammunition https://web.archive.org/web/20070927093727/http://www.lapua.com/uploads/media/Productbrochure338LapuaMagnum_01.pdf 2007-09-27 . .338 Lapua Magnum 300 (19.44) 2,717 (828.1) 4,919 (6,669.2)VihtaVuori Reloading Guide, 2006 https://web.archive.org/web/20070927094837/http://www.lapua.com/uploads/media/ReloadingGuide2006.pdf 2007-09-27 . .375 Chey Tac (9.3×77mm) 315 (24.3) 3,050 (929.6) 7,744 (10,500) .408 Chey Tac (10.2×77mm) 305 (19.8) 3,500 (1,066.8) 8,298 (11,250.5)Cartridges of the World 11th Edition, by Frank C.

The common 254 mm (1:10 inch) rifling twist rate also has to be tightened to stabilize very long projectiles. Such commercially non-existent cartridges are termed "wildcats". The use of a wildcat .338 Lapua Magnum-based cartridge demands the use of a custom or customized rifle with an appropriately cut chamber and fast-twist bore. The firearm action and if a repeating arm is required the magazines must also be able to cope with dimensional increases. An example of such a special .338 caliber extreme range bullet is the German CNC manufactured mono-metal 18.92 gram (292 gr) LM-105 (Cd = 0.2487 at Mach 2.216 – this drag coefficient and the corresponding G1, G7 and G8 ballistic coefficients are established by Doppler radar measurements).LM-105 http://lutzmoeller.net/English/LM-105-long-range-bullet.php#LM_105_Radar_Data https://web.archive.org/web/20140209102339/http://lutzmoeller.net/English/LM-105-long-range-bullet.php#LM_105_Radar_Data February 9, 2014 The LM-105 has a supersonic range of ≈ 1860 m yd -1 at a muzzle velocity of 915 m/s ft/s 0 under International Standard Atmosphere sea level conditions (air density ρ = 1.225 kg/m3). The 2010 version of the LM-105 bullet has an overall length of 54.3 mm in or 6.33 calibers and derives its exceptionally low drag from a radical LD Haack or Sears-Haack profile in the bullet's nose area.

A real-world average G1 BC of around 0.83 or a G7 BC of about 0.42 is commonly adopted by the users of this bullet, for making long-range trajectory predictions using ballistics calculators. In contrast the LM-105 designer Lutz Möller originally calculated an optimistic G1 BC of ≈ 0.93 and a supersonic range of ≈ 2000 m yd -1 at a muzzle velocity of 915 m/s ft/s 0 under International Standard Atmosphere sea level conditions (air density ρ = 1.225 kg/m3). The .343 Lapua Magnum LM-107 was a wildcat cartridge under development based on the standard .338 Lapua Magnum cartridge case.LM-107 .343 Lapua Magnum http://www.lima-wiederladetechnik.de/8,5-mm/LM-107.htm# dead https://web.archive.org/web/20090402152440/http://www.lima-wiederladetechnik.de/8%2C5-mm/LM-107.htm April 2, 2009 The LM-107 was hoped to boost the ballistic performance of the LM-105 by achieving an increase in supersonic range. The 19.3 g (298 gr) LM-107 projectile design is 59 mm in long and has a Haack profiled nose and an Adams profiled tail. The rifling twist rate for the .343 Lapua Magnum LM-107 wildcat cartridge was chosen at 180 mm (1:7 inch), Ø lands = 8.72 mm, Ø grooves = 8.45 mm and loaded with the LM-107 projectile has a cartridge overall length of 107 mm in. The length of the neck is increased from 8,31 to 8,50 mm to support the bigger LM-107 bullet. Several other dimensions of the .338 Lapua Magnum parental cartridge are also changed. The shoulder angle gets steepened from 40° to 60° and the body taper is set at 1°. The throat area is set at a 2° cone-angle. All these modifications make the .343 Lapua Magnum a fairly comprehensively revised wildcat cartridge. Out of a 900 mm in 1 long progressive twist barrel Möller expected to achieve 909 m/s ft/s 0 muzzle velocity. If Möller's design assumptions are correct the LM-107 projectile with a calculated G1 BC of 1.02 will offer a supersonic range of ≈ 2170 m yd -1 at a muzzle velocity of 909 m/s ft/s 0 under International Standard Atmosphere sea level conditions (air density ρ = 1.225 kg/m3). As a parent case .300 Lapua Magnum The commercially successful .338 Lapua Magnum cartridge has functioned as the parent case for the .300 Lapua Magnum, which is essentially a necked-down version of the .338 Lapua Magnum. The .338 cartridge case was used for this since it has the capability to operate with high chamber pressures which, combined with smaller and hence lighter bullets, result in very high muzzle velocities. The Finnish ammunition manufacturer Lapua got the .300 Lapua Magnum C.I.P. certified, so it became an officially registered and sanctioned member of the Finnish "family" of super magnum rifle cartridges. The .300 Lapua Magnum is not commercially available and exists only as a C.I.P. datasheet. It is however still used by a few shooters who produce the cases from .338 Lapua Magnum brass by reshaping the shoulder and neck, and handloading it with .30 calibre bullets. The .300 Lapua Magnum has a 7.33 ml (113 grains H2O) cartridge case capacity. 400px .300 Lapua Magnum maximum C.I.P. cartridge dimensions. All sizes in millimeters (mm). Americans define the shoulder angle at alpha/2 ≈ 25 degrees. The common rifling twist rate for this cartridge is 240 mm (1 in 9.45 in), 4 grooves, Ø lands = 7.62 mm, Ø grooves = 7.82 mm, land width = 4.47 mm and the primer type is large rifle magnum. According to the official C.I.P. rulings the .300 Lapua Magnum can handle up to 440.00 MPa psi on Pmax piezo pressure. This prevails over the C.I.P. decisions and tables edition 2007, that rated the .300 Lapua Magnum at 470.00 MPa psi on Pmax piezo pressure. The large diameter bolt face, combined with the high maximum pressure, means that the .300 Lapua Magnum is normally only chambered in rifles that are capable of handling the resulting high bolt thrust, safely. Chambering such powerful super magnum cartridges in rifles intended for normal magnum rifle cartridges and using 440.00 MPa psi on loads can cause serious or fatal injury to the shooter and bystanders. 7.62 UKM The .338 Lapua Magnum cartridge is also used as the parent case for the German-designed 7.62 UKM, which is essentially a necked-down shortened version of the .338 Lapua Magnum.The 7.62 UKM. A German 300 Magnum Wildcat Extraordinary https://www.angelfire.com/ma/ZERMEL/762ukm.html 1 October 2000 13 June 2023 ZERMEL The use of the .338 cartridge case with its capability to operate at high chamber pressures resulted in a magnum case capable of producing high muzzle velocities. The 7.62 UKM was developed by Michael Uekötter and was C.I.P.-certified in 2002, making it an officially registered and sanctioned member of the Finnish "family" of super magnum rifle cartridges. The 7.62 UKM is not commercially available and exists only as a C.I.P. datasheet. It is however still used by a few shooters who produce the cases from .338 Lapua Magnum brass by reshaping the shoulder and neck, and handloading it with .30 caliber bullets.

As such, .375 Swiss P was designed to be relatively easily rechambered by a rebarreling as a performance upgrade in sturdily built rifles originally designed around the .338 Lapua Magnum chambering.2021-03-25 RUAG Ammotec: .375 SWISS P – improved performance made easy! https://www.edrmagazine.eu/ruag-ammotec-375-swiss-p-improved-performance-made-easy 2021-05-07 edrmagazine.eu en The .375 Swiss P is a rebated rim bottlenecked cartridge that shares its bolt face, rim diameter, overall length, and maximum operating pressure with the .338 Lapua Magnum chambering. It features a larger 15.73 mm on base diameter as found in the .500 Jeffery. This results in a (P1 - R1 = 0.80 mm on) rebated rim.C.I.P. 2018-05-16 C.I.P.

By changing the shape of standard factory cases (decreasing case taper or changing the shoulder geometry) the wildcatter generally increases the case capacity of the factory parent cartridge case, allowing more propellant to be used to generate higher velocities. Besides changing the shape and internal volume of the parent cartridge case, wildcatters also can change the original caliber. Because the .338 Lapua offers a large and exceptionally sturdy, pressure-resistant cartridge case that can be relatively easily reloaded and hence be reused several times, it has become quite popular amongst wildcatters.
