It is essentially a .45 ACP case, necked down to .40 caliber with a 25-degree shoulder. Contents 1History and design 2Performance 3Ammunition and handloading 4Handguns and conversions 5See also 6References 7External links 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."[3] 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.[3][4] According to Guns & Ammo magazine, 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 (15 g) hardball in .45 ACP.[6] 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.[3] Ballistics fall somewhere between the .40 S&W and the 10 mm Auto.[7] 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),[8][9] much closer to the SAAMI maximum pressures for .45 ACP (21,000 psi), and .45 ACP +P (23,000 psi).[10] SAAMI Maximum Average Pressure for 400 Cor-Bon is 35,000 psi.[11] 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]. Pressures for the 400 are in the 23,000 PSI range."[12] The difference between SAAMI maximum average pressure is only 2,500 psi and identical to that of the .40 S&W (35,000 psi).[11] 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 (12 g) bullets at 1,250 ft/s (380 m/s) making it an adequate round for hunting some medium game at close distances.[13] 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.[9][14][15] The .400 Corbon also surpasses the Steel Challenge Shooting Association's stop plate's power actor floor of 120 and qualifies for metallic silhouette Big Bore Competition under IHMSA rules.[16][17] According to Ed Sanow, the 135 gr (8.7 g). JHP penetrated 9 inches (230 mm) of ordnance gelatin and "equals the predicted stopping power of the 10mm 135-grain (8.7 g) JHP loads,"[6] and that the 165 gr (10.7 g). JHP "penetrates an ideal 12.3 inches (310 mm) of gelatin" and "should be a 92-percent stopper, per the Fuller Index."[8] Factory-made ammunition is available from Cor-Bon in a variety of bullet weights and types: 115 gr (7.5 g) Glaser Safety Slugs; 155 gr (10.0 g) DPX; 135 gr (8.7 g) Pow'RBall; 130, 150, and 165 gr (10.7 g) tradition JHPs; and 165 gr (10.7 g) Performance Match;[18] and is sold by major mail-order retailers.[19] Many shooters, however, handload their own ammunition to save money. Fired .45 ACP cases can be resized and trimmed to handload .400 Corbon cartridges.[20] New brass cases are manufactured by Starline Brass and are readily available directly from them and major mail order retailers.[21] According to Starline Brass, "The primer pocket was changed from large pistol primer to small pistol/rifle primer in 12/00. Test results concluded no adverse affect [sic] from switching to small primer pocket. Cor-Bon is now recommending Win. small pistol works best and if using small rifle Remington 7 1/2 works the best."[21] Lee Precision, Inc. offers a .400 Corbon 3-Die set.[22] Redding Reloading, according to their catalog, offers custom made 3-die sets for the .400 Corbon.[23] Lubricating of the bottleneck case can be avoided when starting with .400 Corbon cases by using a carbide .45 ACP sizing die before using the .400 Corbon sizing die. Using a five-stage progressive reloading press makes this less of a chore. Setback of the bullet in the case—which can cause excessive pressure—can be avoided by using a tight roll crimp and, if necessary, Corbin's Hand Cannelure Tool for jacketed bullets.[24] Since the cartridge headspaces on the shoulder rather than the case mouth, a tight crimp will not cause headspace problems.[4] Information on handloads for the .400 Corbon can be found online.[25][9] Les Baer offers both his Baer 1911 Premier II 5" and SOLD
