Compare all 45 ACP ammunition … ARCHIVED; Armory » Reloading. The 10mm Auto is a intriguing round in he handgun world. 230 Grains: Bullet Type. Tracer ammunition for the .45 ACP was manufactured by Frankford Arsenal and by Remington Arms. However, since the proverbial myth of the One Shot Stop round, may seem to have finally died a well-deserved ignoble death, the vitally important concept of follow-up shots comes to the fore! The .45 ACP is an effective combat pistol cartridge that combines accuracy and stopping power for use against human targets. Over time, a series of improved designs were offered, culminating in the adoption in 1911 of the "Cal. [ARCHIVED THREAD] - .45 ACP Loads - Velocity and Bullet Types. The enterprising statisticians among you will have to settle for this more practical display. Tracer ammunition was identified by painting the bullet tip red. The ammunition I received ranged from simple ball loads to exotic self-defense rounds that could easily be called art due to the quality of their machining. The first production, at Frankford Arsenal, was marked "F A 8 11", for the August 1911 date. I carried a SIG Sauer P220 .45ACP for decades as a LEO. The only common pistol round more powerful is the .357 Magnum and the 50 Action Express (the 50 being not so popular really)The 45 ACP was designed by the late … 45 ACP velocity adventure, I was imagining that there would be a large difference between the standard 5” barrel and the short 3.3” on the S&W Shield. The latter inevitably produce a highly compressed shock wave, audible as a loud "crack", a small sonic boom, while they travel through the air. Other US military cartridges include: tracer M26 (red tip), blank M1921 (rolled crimp, red paper wad), M12 and M15 shot shells, and M9 dummy (holes in case). 45 ACP is very similar, with a 230 grain (gr) lead bullet that travels at an impressive 830 feet per second (fps). To equal the impact of a .45 ACP bullet, the 1-pound weight needs a velocity of 27.1 fps and must be dropped from a height of 11.4 feet. Popular derivative versions of the .45 ACP are .45 Super and .460 Rowland. A sharp eye will notice that virtually all 230gr forty five ball loads are still nearly identical to the old 800fps standard going back to the First World War with some being slower yet. 543 ft. lbs. After successful military trials, it was adopted as the standard chambering for Colt's M1911 pistol. This is a significantly large permanent wound cavity for a handgun projectile. He is an active competition shooter with 14 medals from Camp Perry. Overall, it appears the .45 Auto is slightly faster in comparable products, but shooters will not see a significant difference between the two. Rounds are available from 68 grains to 300 grains (4.4 g to 16.5 g) with a common load being the standard military loading of a 230-grain (15 g) FMJ bullet (for comparison, the most common 9mm load is 115 grains (7.5 g), quite literally half the weight). AR15.COM is the world’s largest firearm community and is a gathering place for firearm enthusiasts of all types. Gun writer, Josh Wayner, reveals the results of his extensive .45 ACP velocity trial, putting the classic caliber to the test. Nice try tho my guy, Theoretically you are correct, as far as mid bore calibers are concerned. Curiously, the Sig P320C with a 3.9” barrel was, by all accounts, only lagging behind the longer guns by a hair, and in some cases was actually faster. This massive test comprised of over a thousand separate data points and the sheer amount of information wouldn’t translate reliably into this article or help to illustrate the results. During the late 19th century and early 20th century, the U.S. Cavalry began trials to replace their sidearm arsenal of issued .45 Colt Single Action Army (SAA) in favor of the more modern and versatile double-action revolver in .45 Colt. Today, most NATO militaries use sidearms chambered for the 9×19mm Parabellum cartridge, but the effectiveness of the .45 ACP cartridge has ensured its continued popularity with large caliber sport shooters, especially in the United States. This .45 ACP velocity study was designed to shed some light on the idea that the .45 ACP has either surpassed other cartridges in terms of power and utility or finally reached obsolescence. These numbers appear a bit low for the 5″ barrel. The cartridge was designed by John Browning for Colt, but the most influential person in selecting the cartridge was Army Ordnance member Gen. John T. Thompson. The most unexpected thing aside from the general similarity of all loads across all barrel lengths was that the longest barrel wasn’t the fastest. The standard issue military .45 ACP round has 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 from the M1A1 Thompson submachine gun. Testing was done using an Oehler 35P Proof Chronograph at a distance of five feet from the muzzle in a testing environment of 30 degrees Fahrenheit.
