For those who follow the energy dump and/or hydrostatic shock theories of wounding ballistics, this is ideal. This is a significantly large permanent wound cavity for a handgun projectile. In tests against ballistic gelatin, a 185 grain hollow point traveling at 1,050 feet per second expanded to about.

In its expanding hollow point form, it is also particularly effective against human targets. Its large 11.5mm diameter creates a more substantial permanent wound channel versus smaller calibers, which can lower blood pressure rapidly if critical organs of the circulatory system are hit. In its non-expanding full metal jacket (FMJ) version, the 45 ACP cartridge has a reputation for effectiveness against human targets because of its heavy mass, having the capacity to penetrate tissue deeply, and damage the central nervous system.

Some makers of pistols chambered in 45 ACP AMMO do not certify them to use Plus P ammunition. 357 SIG), which due to a low bolt thrust helps extend service life of weapons in which it is used. The cartridge operates at a relatively low maximum chamber pressure rating of 21,000 psi (145 MPa) (compared to 35,000 psi/241 MPa for 9mm Parabellum and. The cartridge comes in various specialty rounds of varying weights and performance levels as well. The standard issue, military 45 ACP cartridge contains a 230-grain bullet that travels at approximately 830 feet per second when fired from the government issue M1911A1 pistol, and approximately 950 feet per second fired from the Thompson M1A1 submachine gun. It combines accuracy as well as stopping power for use against human targets, has relatively low muzzle blast and flash, and it produces a stout, but manageable recoil in handguns (made worse in compact models). The 45 ACP AMMO is an effective combat pistol cartridge. The SAAMI pressure limit for the 45 ACP AMMO is set at 21,000 psi (144.79 MPa) piezo pressure, while the SAAMI pressure limit for the 45 ACP +P is set at 23,000 psi (158.58 MPa), piezo pressure. regulated countries are currently (2016) proof tested at 170 MPa (25,000 psi) PE piezo pressure. This means that 45 ACP AMMO chambered arms in C.I.P. In CIP-regulated countries every pistol cartridge combination has to be proofed at 130% of this maximum CIP pressure to certify for sale to consumers.

Īccording to Commission Internationale Permanente pour l’Epreuve des Armes à Feu Portatives rulings, the 45 ACP cartridge case can handle up to 131 MPa (19,000 psi) P max piezo pressure. The cartridge headspaces on the mouth of the case at the 元 datum reference. 147″ (3.73 mm) and the primer type is large pistol. The common rifling twist rate for this cartridge is 1 in 16 in (406 mm), 6 grooves, Ø lands =. All dimensions are in inches (millimeter)
