The Shield, very WAY. I was involved in two shooting with one and it worked great, however shot placement was good. 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. Every load and weapon tested are currently commercially available and unaltered from their factory form. Tracer ammunition was identified by painting the bullet tip red. Standard 9mm NATO ammunition has limited armor penetration capability − a deficiency with .45 ACP whose large, slow bullet does not penetrate armor to any great extent. I do FBI protocol ballistic shoots for a major manufacturer of law enforcement ammunition and can tell you from first hand experience that velocity is secondary to bullet placement, design and construction. HST +P from a Kimber Custom II at 930 fps. 835 fps. By Josh Wayner The cartridge/pistol combination was quite successful but not satisfactory for U.S. military purposes. Is it the most effective cartridge available today? We are currently using Missouri Bullet company 185 SWC coated bullets and 3.6 grs. I love mine and my 357s and 9mms and 10mms and 44s and…….. Joe Your right about the .45 ACP. 9mm vs 45 ACP Ballistics. 45 ACP leaving m1911 muzzle 00:27: Rifle bullet penetrating barrier with explosive ejecta 00:33: M1A cycling 7. Rather than the standard 18,000 psi of the 45 ACP, the +P load will average 21,000 to 22,000 psi. Therefore it makes logistical sense that velocity lost it shorter barrels is quite small compared to other calibers. However, there are occasions when the shorter .45 ACP tubes produce greater velocity than the longer barrels. We, my son and I, shoot bullseye matches in Arizona. [ARCHIVED THREAD] - .45 ACP Loads - Velocity and Bullet Types. I have 15 + 1 capacity. I was fortunate to have a small pile of different .45 pistols passing through at the time, so I tested actual velocity from a range of pistols from compact to full-size. It is a great cartridge. I agree with Ya Mamma. 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. What you see is what you get here. In terms of velocity, the 7.62x25mm begins where the .45 ACP leaves off, at approximately 1,200 feet per second. A longer barrel will ALWAYS produce higher muzzle velocity regardless of which s&w m&p is ur bff. Colt / .45 AC (Winchester Repeating Arms Company), This page was last edited on 18 December 2020, at 13:41. Ever hear of a P220 in 9 x 19 mm? maybe the sig has polygonal barrels like the glock…..they seem to give faster readings than traditional barrels. 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. Because of these inherent low pressures of the standard pressure round, however, compensators and brakes have little effect until +P and Super loads are utilized.[15]. Period. The colder temperature allows the guns to remain cool between strings and remove error due to the weapon heating up. ITEM 45-185. Some of you may believe that this is too cold to test reliably, but a sampling of loads were tested at both air temperature and at a warm seventy degrees. #OldCowboy, Some 45 ACP loads show all the velocity we could ask for. Gun writer, Josh Wayner, reveals the results of his extensive .45 ACP velocity trial, putting the classic caliber to the test. 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. After the example of the Cavalry, the Army in turn had fielded versions of double-action revolvers in .38 Long Colt. 543 ft. lbs. These are the +P-rated loadings. The results proved interesting to say the least. Brass: Primer. The Shield 45 did shockingly well in my . UGH! After successful military trials, it was adopted as the standard chambering for Colt's M1911 pistol. Tags: 45 acp 45 auto 45 cal geco ammunition full metal jacket. Another item that bears out your conclusions is firing a 45 ACP and or loading for a 45 ACP in longer barrels such as an 18 inch rifle barrel. DWM, which submitted two Parabellums chambered in .45 ACP, withdrew from testing after the first round of tests, for unspecified reasons.[8]. [16][17][18] While high capacity firearms are available in .45 ACP, the greater length and diameter of the .45 ACP means that the grip of the pistol must be longer and wider than the grip of a comparable pistol of a smaller caliber; this increase in grip size can make the pistol difficult to use for shooters with smaller hands. The original round that passed the testing fired a 200 grain (13 g) bullet at 900 ft/s (275 m/s), but after a number of rounds of revisions between Winchester Repeating Arms, Frankford Arsenal, and Union Metallic Cartridge, it ended up using a 230 grain (14.9 g) bullet fired at a nominal velocity of 850 ft/s (260 m/s). James, I don’t think the author was judging different firearms for accuracy or recoil, but addressing the ‘lack of velocity’ argument against short-barreled .45acp’s – which I think he showed very well. Even my teenage granddaughters enjoy shooting it. This means that .45 ACP chambered arms in C.I.P.

Or does that add too many variables? This is because of the higher powers achievable with .45 Super, and +P loads. Nice try tho my guy, Theoretically you are correct, as far as mid bore calibers are concerned. It is my opinion that this caliber isn’t going anywhere anytime fast. In its non-expanding full metal jacket (FMJ) version, the .45 ACP cartridge has a reputation for effectiveness against human targets because its heavy mass has the capacity to penetrate tissue deeply and damage the central nervous system, and its large 11.5mm diameter creates a more substantial permanent wound channel than other calibers, which can lower blood pressure rapidly if critical organs of the circulatory system are hit. By 1906, bids from six makers were submitted, among them Browning's design, submitted by Colt. The SAAMI pressure limit for the .45 ACP is set at 21,000 psi (144.79 MPa) piezo pressure,[13] while 45 ACP Muzzle Velocity. 45 ACP +P 45 ACP +P Ammo - 185 gr. For the most part, the velocity pattern was consistent with barrel length, meaning speed tapered off a bit as the barrels go… Our patented recoil system increases accuracy and service lifeПатрон CCI Standart Velocity Ammo, кал. Over time, a series of improved designs were offered, culminating in the adoption in 1911 of the "Cal. doubled in size…and since .45 ACP is bigger to start with, it became massive in the end. Before we go much further, we should discuss 9mm vs 45 ballistics, and more importantly, what that information means for you. My CCW is a Colt Commander, 10 rnd mag, I have put over 3500 rnds through it and it has not failed to function properly yet. The cartridge also comes in various specialty rounds of varying weights and performance levels.[2]. I am here today thanks to a 1911 45 manufactured in 1917. 230 Grains: Bullet Type. 45ACP +P ammo is externally/dimensionally identical to 45 ACP ammo and can be fired in any 45 ACP firearm that is in normal operating condition. 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. Ron, where were you a LEO carrying a P220? These cartridges have the same external dimensions as the standard-pressure cartridges and will chamber and fire in all firearms designed for the standard-pressure loadings. The Rowland operates at a developer established 40,000 psi (280 MPa) SAAMI and may only be used within a select group of firearms significantly modified for this purpose; the Rowland case is 0.057 inches (1.4 mm) longer specifically to prevent it from being chambered in standard .45 ACP firearms. the SAAMI pressure limit for the .45 ACP +P is set at 23,000 psi (158.58 MPa), piezo pressure. I would go so far as to say that in terms of functional lethality, the short 3.3” barrel loses nothing to the longer barrels. I knew that rifle calibers such as .308 didn’t lose much if anything going from 26” to 13.5”, so imagine my surprise when the exact results came about from my most recent test. 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 has 1.62 mL (25 grains H2O) cartridge case capacity. Slow fire is at reduces 50 yard targets at 25 yards. While the 147gr Federal HST expanded from 9mm (roughly .35cal) to on average 15mm or .61″, the .45 ACP expanded from (again, roughly) 11.5mm to 25mm (.45″ to 1″) Both (roughly!) This ammunition was available to the United States Border Patrol as early as 1940 and was used through World War II for emergency signalling by downed United States Navy and Marine Corps air crew. The .45 ACP is an effective combat pistol cartridge that combines accuracy and stopping power for use against human targets. 45 ACP velocity testing considering that it is shorter than most people think a .45 ACP handgun should be. The Shield loses in no areas in my mind. AZ perhaps. That being said, I am not openly advocating this as a solution for everyone. The .45 ACP offers a tremendous advantage in this respect, and we haven’t really had a need to go the same distance in technology with the .45 ACP. The .45 ACP (11.43×23mm) (Automatic Colt Pistol), also known as the .45 Auto by C.I.P. The cartridge was co-developed by Tom Fergerson and Ace Hindman. Bottom line, the .45 ACP is the better self-defense cartridge, and does its best work at standard velocity. Range / Target: Muzzle Velocity. .45 ACP ('08).45 ACP ('15).45 Colt.45 Super.460 Rowland.223 Rifle Acknowledgements. 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. This is a common practice for updating older cartridges to match the better quality of materials and workmanship in modern firearms.[19]. [14] A factor rated by the recent FBI testing was accuracy and time to recover. Yes sir, AZDPS. I think this is a berral half short or half long thing. It is dimensionally similar to the .45 ACP round but has a thicker case wall and is loaded to higher pressures, which offers an average 300 feet per second (91 m/s) improvement in muzzle velocity over the .45 ACP. [19] In 1985, the .45 ACP M1911A1 pistol was replaced by the Beretta M9 9mm pistol as the main sidearm of the U.S. military, although select Special Operations units continue to use the M1911A1 or other .45 ACP pistols. .45 ACP is a very controllable defense round. In the case of the .45 ACP, the new standard cartridge pressure is 21,000 psi (140 MPa) and the SAAMI .45 ACP +P standard is 23,000 psi (160 MPa). The 5” 1911 is a standard for the .45 ACP and I found that it was playing a close game with Sig’s 4.7” P320. Interestingly enough, people who fear the recoil of the 1911 in .45 ACP caliber will shoot a .357 Magnum and think nothing of it. NO WAY. 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.
