It is essentially a .45 ACP case, necked down to .40 caliber with a 25-degree shoulder. History and design Peter Pi, founder of Cor-Bon and the designer of the cartridge, explained his reason for developing the cartridge: "Velocity is the key to making hollowpoint bullets work. The added velocity assures that the hollowpoint will open up even if plugged with material. This reduces the risk of overpenetration and allows the action of the hollowpoint bullet to dump the available energy into the target."The 10mm Auto Cartridge, "Part 5: 10mm "Offspring" and "Stepchildren," quoting an expired Cor-bon webpage. Retrieved July 5, 2008 https://web.archive.org/web/20150213081333/http://www.bren-ten.com/website/id7.html February 13, 2015 . Pi said because he wanted the .400 Corbon to be easy for handloaders to make, he based the cartridge on the ubiquitous .45 ACP so that an ample supply of cases was readily available, gave the shoulder a 25-degree angle, and head-spaced it on the case shoulder rather than the mouth so that over-all-length is not critical and the bullet can take a tight roll crimp to avoid setback and to get a more efficient powder burn.Rees Clair Storm From The East 1999 Guns Magazine 45 6 FindArticles http://www.findarticles.com/p/articles/mi_m0BQY/is_6_45/ai_55605616 https://web.archive.org/web/20070215172128/http://www.findarticles.com/p/articles/mi_m0BQY/is_6_45/ai_55605616 February 15, 2007 usurped Performance According to Guns & Ammo magazine, Performance is on a par with the 10 mm, yet pressures are much milder. Factory ammo is loaded to +P .45 levels, but the lighter bullet weights make recoil comparable to .45 hardball loads. Felt recoil is a little sharper but still very controllable.Guns & Ammo, "1911 Hot Rods" https://web.archive.org/web/20090617072247/http://www.handgunsmag.com/ammunition/1911_hot_rods/index1.html June 17, 2009 Because of its relatively high velocity for a handgun round, the .400 Corbon offers a very flat trajectory, which in turn allows the firearms chambered for it more effective range. Ed Sanow also felt recoil was equivalent to 230 gr on hardball in .45 ACP.http://nordicg3k.tripod.com//sitebuildercontent/sitebuilderpictures/handguns_aug96-04.jpg Handguns, "400 Cor-Bon: Sizzling New Auto Pistol Cartridge," by Ed Sanow, p. 57, August 1996 Tripod.com June 27, 2017 In addition, the bottleneck case can function better than a straight case with a wider variety of bullet shapes and sizes and allows the use of fully supported barrels. Ballistics fall somewhere between the .40 S&W and the 10 mm Auto. Unlike the 10 mm which operates at a SAAMI maximum of 37,500 psi, the .400 Corbon operates at 29,000 psi (although one source states that the pressure is 26,500 psi),http://nordicg3k.tripod.com//sitebuildercontent/sitebuilderpictures/handguns_aug96-02.jpg Handguns, "400 Cor-Bon: Sizzling New Auto Pistol Cartridge," by Ed Sanow, p. 55, August 1996 Tripod.com June 27, 2017http://www.recguns.com/Sources/IVG12.html recguns.com www.Recguns.com June 27, 2017 https://web.archive.org/web/20160116012707/http://www.recguns.com/Sources/IVG12.html January 16, 2016 dead mdy-all much closer to the SAAMI maximum pressures for .45 ACP (21,000 psi), and .45 ACP +P (23,000 psi).http://www.lasc.us/SAAMIMaxPressure.htm Max Chamber Pressure - SAAMI Specs www.LASC.us June 27, 2017 SAAMI Maximum Average Pressure for 400 Cor-Bon is 35,000 psi.http://www.saami.org/specifications_and_information/specifications/Velocity_Pressure_CfPR.pdf Velocity and Piezoelectric Transducer Pressure: Centerfire Pistol & Revolver January 30, 2015 dead https://web.archive.org/web/20150319133613/http://saami.org/specifications_and_information/specifications/Velocity_Pressure_CfPR.pdf March 19, 2015 In 2008, Michael Shovel, then National Sales Manager for CORBON/Glaser, stated that Cor-Bon "submitted the 400 COR-BON to SAAMI and it was approved [in 2006].

The .400 Corbon is a versatile cartridge useful for target shooting, practical shooting competition, self-defense, and the handgun hunting of small and medium game. The loads with the lighter bullets are appropriate for small game. Handloaders have worked up safe loads using 180 gr on bullets at 1250 ft/s m/s on making it an adequate round for hunting some medium game at close distances.http://bananafufu.blogspot.com/2008/04/400-corbon-vs-10mm-conclusions.html 400 Corbon vs. 10mm -- conclusions BananaFufu.Blogspot.com June 27, 2017 For practical shooting competitors, the .400 Corbon makes IPSC Major Power Factor of 175 and surpasses the IDPA Enhanced Service Pistol's Power Floor of 125,000 in most loads using a 5-inch barrel.http://www.ipsc.org/ International Practical Shooting Confederation www.IPSC.org June 27, 2017http://www.idpa.com/ IDPA - Welcome!

Feed reliability with this cartridge improves with very stiff magazine springs, particularly in 1911 style pistols, as too light a magazine spring can cause nose dive jams when the magazine is fully loaded.
