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 ...
The standard-issue military .45 ACP cartridge uses a 230 gr (15 g; 0.53 oz) round-nose bullet at approximately 830 ft/s (250 m/s) fired from a government-issue M1911A1 pistol. It operates at a relatively low maximum chamber pressure rating of 21,000 psi (140 MPa ), compared to 35,000 psi (240 MPa ) for both 9mm Parabellum and .40 S&W , which ...
Common rifle cartridges, from the largest .50 BMG to the smallest .22 Long Rifle with a $1 United States dollar bill in the background as a reference point.. This is a table of selected pistol/submachine gun and rifle/machine gun cartridges by common name.
In the revolver division major scoring can be achieved with a 9 mm bullet diameter, but with a power factor of 170. A popular cartridge in revolver is the .45 ACP since it is easier to use with speed loaders. From 2017, revolvers with a capacity of seven rounds or more are scored with minor power factor.
The .450 SMC is a .45 ACP wildcat cartridge for use in robust .45 ACP firearms that uses a modified .308 Winchester case with a small rifle primer adapted for use in modern .45 ACP firearms. Only 1911 pistols or heavier firearms with upgraded heavier springs are recommended.
.45 ACP: The standard US pistol round for about 75 years. Typical .45 ACP loads are subsonic. [54].45 Colt: a more powerful 45-calibre revolver round using a longer cartridge. The .45 Colt was designed for the Colt Single Action Army and adopted by the US Army in 1873. Other 45-calibre single-action and double-action revolvers also use this round.
Example of a ballistic table for a given 7.62×51mm NATO load. Bullet drop and wind drift are shown both in mrad and MOA.. A ballistic table or ballistic chart, also known as the data of previous engagements (DOPE) chart, is a reference data chart used in long-range shooting to predict the trajectory of a projectile and compensate for physical effects of gravity and wind drift, in order to ...
Originally, the maximum bullet weight of the .45 GAP was 200 grains (13 g). In order to provide terminal ballistics that matched the standard 230-grain (15 g) .45 ACP loads, the .45 GAP was designed to operate at a higher standard pressure—roughly equivalent to the higher pressures found in .45 ACP "+P" rounds. Since the .45 GAP has a much ...
