It is designed to provide an increase in performance over the .375 H&H cartridge within the context of a standard-length rifle action. The cartridge was designed in partnership by Hornady and Ruger. In 2007, it was released commercially and chambered in the Ruger Hawkeye African and the Ruger Hawkeye Alaskan rifles. Anderson Petter 375 Ruger – en värdig arvtagare? Jakt & Jägare 23 January 2009 sv https://www.jaktojagare.se/kategorier/vapen-och-utrustning/375-ruger---en-vardig-arvtagare-/ 2017-09-28 https://web.archive.org/web/20170928145956/https://www.jaktojagare.se/kategorier/vapen-och-utrustning/375-ruger---en-vardig-arvtagare-/ 2017-09-28 dead Design & Specifications Like the .376 Steyr that originates from the 9.3×64mm Brenneke and the .375 Dakota proprietary cartridge that originates from the .404 Jeffery, the .375 Ruger was designed to compete with the .375 H&H Magnum, yet have the advantage of having a rimless, beltless case and can function through a standard-length bolt-action rifle due to a shorter overall length. The .375 Ruger uses a unique cartridge case designed by Hornady and Ruger. The case is of a rimless design having the base and rim diameter of .532 in mm on, which is the same diameter as the belt on belted magnum cases based on the .300 H&H Magnum and .375 H&H Magnum. This allows the cartridge to have a greater case capacity than a belted magnum case given cases of equal length. As Ruger intended the cartridge to be chambered in standard-length bolt-action rifles, the case length was kept to 2.580 in mm on, which is only .04 in mm on longer than the .270 Winchester case. The maximum overall length of the cartridge is 3.340 in mm on, which is similar to the maximum overall length of standard-length cartridges such as the .338 Winchester Magnum or the .30-06 Springfield. Unlike Remington Ultra Magnum cartridges, the Ruger Magnums can be chambered in standard-length bolt-action rifles. This allowed Ruger to chamber the cartridge in their existing standard length M77 rifle, without needing to use their M77 Safari Magnum Rifle. While the .375 H&H Magnum is longer than the .375 Ruger, the latter cartridge has a 4% greater case capacity than the Holland & Holland cartridge, 99 gr. of water (6.42 cm3) compared to the H&H's 95. This is due to the .375 H&H Magnum having a long, tapered body, while the .375 Ruger follows modern cartridge designs in that it has very little taper and a sharper shoulder. 500px|alt=375 Ruger Cartridge SAAMI Schematic|.375 Ruger SAAMI cartridge dimensions - all dimensions in inches (mm) Cartridge standards for the .375 Ruger were issued by SAAMI in June 2007. SAAMI recommends a six-groove barrel having a bore Ø of .366 in mm on and a groove Ø of .376 in mm on with a groove width of .115 in mm on. The recommended rate of twist is one revolution in 12 in mm 1 on. Recommended maximum pressure for the cartridge is 62000 psi bar on. Performance Currently, Hornady and Double Tap manufacture ammunition for the .375 Ruger cartridge. The Hornady Superformance ammunition drives a 270 gr g 1 on SP-RP bullet at 2840 ft/s on and the 300 gr g 1 on DGS and DGX bullets at 2660 ft/s on. The original Hornady loads were not Superformance, but had the same velocity, with the Superformance loading offering lower recoil due to a smaller propellant charge, and less steep pressure curve. The Double Tap achieves 2825 ft/s on and 4700 ftlb on with a 270-grain Barnes TSX from a 23-inch barrel Ruger 77 African. The .375 Ruger's greater case capacity, and the "short fat" cartridge efficiency lead to increases in the neighborhood of 150 to 200 fps over the .375 H&H Magnum cartridge. Their capabilities for big game hunting remain essentially comparable. The muzzle velocity advantage can allow rifles chambered in .375 Ruger to use 20 inch barrels and still match the ballistics of the .375 H&H Magnum with a 26 inch barrel. Combined with the fact that the .375 Ruger fits in a shorter action, it allows hunters to use rifles that are shorter, lighter, handier and cheaper than muzzle velocity wise comparable magnum-action length action rifles chambered in .375 H&H Magnum. Since 2015, O.F. Mossberg & Sons produced bolt-action rifles of the "Patriot" series chambered in .375 Ruger with different stock options.https://www.americanrifleman.org/articles/2015/3/25/new-for-2015-mossberg-patriot/ American Rifleman Editors' Picks—New for 2015: Mossberg Patriot 2018-03-05 https://web.archive.org/web/20180305064028/https://www.americanrifleman.org/articles/2015/3/25/new-for-2015-mossberg-patriot/ 2020-03-01 2018-03-05https://www.mossberg.com/category/series/mossberg-patriot/ Mossberg Patriot O.F.

The case is of a rimless design having the base and rim diameter of .532 in mm on, which is the same diameter of the belt on belted magnum cases based on the .300 H&H Magnum and .375 H&H Magnum. This allows the cartridge to have a greater case capacity than a belted magnum case given cases of equal length. As Ruger intended the cartridge to be chambered in short-length bolt-action rifles, the case length was shortened to 2.10 in mm on, which is similar to the .308 Winchester case. Unlike Winchester Short Magnum cartridges, the Ruger Compact Magnums share the same diameter from case head to body. This allowed Ruger to chamber the cartridge without extensively redesigning their Ruger M77 rifle to adapt them to the new Ruger cartridge. .338 Ruger Compact Magnum The .338 Ruger Compact Magnum or .338 RCM is a rimless, short-length rifle cartridge based on the .375 Ruger case. It was designed by Ruger and Hornady and released in 2008 and chambered in various Ruger rifles. The goal was to create a shorter cartridge than the big .338 magnums that would fit in a more compact rifle with nearly the same performance. Similar to the design ideas for the WSM cartridge family, but somewhat narrower which will frequently allow one more cartridge in the rifle magazine than the WSM equivalent.http://www.hornady.com/in-the-news/latest-news/ruger-compact-magnum-cartridges-review Hornady Ruger Compact Magnum Cartridge Review 2018-11-27 https://web.archive.org/web/20160408020124/http://www.hornady.com/in-the-news/latest-news/ruger-compact-magnum-cartridges-review 2016-04-08 dead This round is designed for hunting medium- to large-sized North American game. .416 Ruger The .416 Ruger is a beltless, rimless, bottle-necked cartridge designed as a joint venture by Hornady and Ruger in 2008. The cartridge is based on the .375 Ruger case, which was necked up to accept a .416 in mm on bullet. It was designed as a dangerous game cartridge, particularly for use in Alaska and Africa. 300 Precision Rifle Cartridge The .375 Ruger cartridge functioned as the parent case for the 300 Precision Rifle Cartridge (300 PRC), which is essentially a necked-down form of the .375 Ruger. Hornady acquired SAAMI standardization for the 300 PRC in 2018.https://saami.org/wp-content/uploads/2018/07/300-PRC-Public-Introduction.pdf New Cartridge & Chamber SAAMI Drawing 300 Precision Rifle Cartridge (300 PRC)June 2026 InternetArchiveBot http://bulletin.accurateshooter.com/2018/08/its-official-saami-approves-hornady-6-5-prc-and-300-prc/ It's Official — SAAMI Approves Hornady 6.5 PRC and 300 PRC August 13, 2018 bulletin.accurateshooter.com 2020-03-01 In 2019 C.I.P. also standardized the cartridge.https://bobp.cip-bobp.org/uploads/tdcc/tab-i/300-prc-190408-en.pdf C.I.P.

The round is designed particularly for use at extended range, with high cartridge case capacity for caliber, longer than typical bullet projection (a "standard" case length is paired with a "long action" cartridge overall length to prevent bullets from intruding on the powder column), and a throat design that minimizes bullet yaw prior to contact with the rifling. Accordingly, the cartridge is optimized for loading relatively long and heavy .308 diameter very-low-drag bullets.https://ammo.com/comparison/300-prc-vs-338-lapua 300 PRC vs 338 Lapua 2023-07-22 Ammo.com en 2023-07-22https://ammo.com/comparison/300prc-vs-300win-mag 300 PRC vs 300 Win Mag 2023-07-22 Ammo.com en 2023-07-22 Rifles chambered for the 300 PRC must be capable of handling (magnum-action length) 3.70 in mm 2 on overall length cartridges.https://www.shootingtimes.com/editorial/300-prc-better-than-the-rest/330587 .300 PRC vs. Other .30-Caliber Magnums von Benedikt Joseph 2019-01-09 Shooting Times en 2020-03-01https://www.gunsandammo.com/editorial/review-hornady-300-prc/358208 .300 PRC Review: Everything You Need to Know Beckstrand Tom 2019-03-12 Guns and Ammo en 2020-03-01https://backfire.tv/prc-cartridge-comparison/ 6.5 PRC vs 7 PRC vs 300 PRC: A ballistics comparison (plus hands-on experience) Harmer Jim 2022-11-21 Backfire en 2023-07-17300 PRC load data for 24 inch (610 mm) barrel length In 2019 the U.S. Department of Defense selected the 300 PRC cartridge as a chambering option for their Barrett MRAD multi-caliber sniper rifle platform.https://www.militarytimes.com/off-duty/gearscout/2019/01/02/hornady-to-supply-300-prc-ammunition-to-us-spec-ops-snipers/ Hornady to supply 300 PRC ammunition to US spec ops snipers, Jan 2, 2019 The U.S. Special Operations Command (SOCOM), requested ammunition manufacturers to develop a cartridge that would give snipers a 50% hit probability on a man seized target at 2,000 yards (1,829 m).https://www.browning.com/news/tech-terms/caliber-300prc.html - 300 PRC In the early 2020s the .300 Norma Magnum, offering about 8.9% additional case capacity, was eventually taken into service as the new .30 magnum chambering for the MRAD platform by the U.S. Army. 6.5 and 7mm Precision Rifle Cartridges The .375 Ruger cartridge case was used by Hornady as the basis for new long-range cartridges, since it had the capability to operate with high chamber pressures, which combined with a neck and barrel throat optimized for loading relatively long and heavy very-low-drag bullets without the need to seat the bullets deeply recessed into the case result in adequate muzzle velocities from bolt-action rifles.
