So if low velocity and low round count are bad, then the pmr30 would be pretty close to ideal. Another area to address is velocity. In terms of velocity, the 7.62x25mm begins where the .45 ACP leaves off, at approximately 1,200 feet per second. 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. .45 ACP loads use fast burning powders and for the most part full ignition takes place inside the barrels be they 3.3″ such as the Shield or 5″ such as the M1911 which is what I cut my teeth on in the Marine Corps beginning in 1966. ITEM 45-185. The .45 ACP is a pussycat in recoil compared to a short barrelled .357, even when shooting .38 Special loads. It 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 .40 S&W), which due to a low bolt thrust helps extend service life of weapons. He is an active competition shooter with 14 medals from Camp Perry. Suppressors reduce the audible "report" by slowing and channeling the high speed gas generated by the burning/expanding gunpowder before it exits the muzzle resulting in a muffled "cough". cartridge dimensions. 45 ACP velocity testing considering that it is shorter than most people think a .45 ACP handgun should be. 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 colder temperature allows the guns to remain cool between strings and remove error due to the weapon heating up. Liberty Civil Defense .45 ACP ammunition is a high velocity, extremely accurate load designed for self-defense. Popular derivative versions of the .45 ACP are .45 Super and .460 Rowland. 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. HST +P from a Kimber Custom II at 930 fps. I wouldn’t call it a debate, however there were some sideways comments and tense laughs across the course of the conversation. In fact, standard pressure 230 grain FMJ loads are, perhaps, the .45 owner’s best choice for bears since they penetrate deep and make wider wounds than non-expanding 10mm’s. Traded for it in ‘Nam, the ARVN were still using WW11 weapons at the time, my rifle jammed, the .45 did not. Is it intended for bulls-eye shooting or WHAT???!!! Complete 45 ACP ammunition ballistics Chart. [2] The round was developed due to a lack of stopping power experienced in the Moro Rebellion using the .38 Long Colt. The cartridge also has relatively low muzzle blast and flash, as well as moderate recoil. Thing is that it isn’t really supposed to be. I have 15 + 1 capacity. This experience and the Thompson–LaGarde Tests of 1904 led the Army and the Cavalry to decide a minimum of .45 caliber was required in a new handgun. To get a picture of the modern .45 ACP's velocity, I contacted several manufacturers and received 33 ammunition offerings to test. Only DWM, Savage, and Colt made the first cut. These are the +P-rated loadings. [19] The Super is dimensionally identical to the .45 ACP; however, the cartridge carries a developer established pressure of 28,500 psi (197 MPa) and requires minor modification of firearms for use. [3][4][5][6] The then-current issue rifle, the .30-40 Krag, had also failed to stop Moro warriors effectively;[7] the British had similar lack-of-stopping-power issues switching to the .303 British, which resulted in the development of the dum-dum bullet in an attempt to compensate for the round's deficiencies. 835 fps. Range / Target: Muzzle Velocity. Though he preferred the .45 ACP over the 9mm, the celebrated gun writer Jeff Cooper still wasn't satisfied with just those two choices. 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. Ever hear of a P220 in 9 x 19 mm? The cartridge expands to approximately 0.35 to 0.72”. 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. 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. 543 ft. lbs. I taught quite a few classes in the Hudson Valley NY area, generally Federal, State and/or Municipal LE Agencies. After successful military trials, it was adopted as the standard chambering for Colt's M1911 pistol. Does this data also apply to even shorter barrels, such as the 2.5″ charter arms pitbull .45 acp? 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. Colt / .45 AC (Winchester Repeating Arms Company), This page was last edited on 18 December 2020, at 13:41. What is more important a gun or your love ones..i carry the heavy 45 acp springfield, and believe me I don’t care about that heavy gun. It 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 .40 S&W, 37,500 psi/259 MPa for 10mm Auto, 40,000 psi/276 MPa for .357 SIG), which due to a low bolt thrust helps extend service life of weapons in which it is used. Cheaper: To convert an AR-15 to a .45 ACP chambering costs over $700 on top of the purchase of the AR-15. While slightly decreasing penetration and likewise the chance of hitting a vital organ, a large diameter wound will cause more blood loss. Out of the box I considered it to be the finest DA/SA pistol I’d fired in the caliber. 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! [11] All dimensions are in inches (millimeter), The common rifling twist rate for this cartridge is 1 in 16 in (406 mm), 6 grooves, Ø lands = .442" (11.23 mm), Ø grooves = .45" (11.43 mm), land width = .147" (3.73 mm) and the primer type is large pistol. Before we go much further, we should discuss 9mm vs 45 ballistics, and more importantly, what that information means for you. You will discover velocity increases in these longer barrels is actually quite minimal, compared to other calibers. maybe the sig has polygonal barrels like the glock…..they seem to give faster readings than traditional barrels. 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 … [ARCHIVED THREAD] - .45 ACP Loads - Velocity and Bullet Types. As is the case with many 100-year-plus cartridges, the following of the .45 ACP is based in practicality and myth in equal amounts. Having shot the .45 since the early 60’s in plinking and Top Flight Competition (Nationals) and have found out that the reason it is ‘dis-respected’ is people are afraid of recoil and they just plain old ‘can’t shoot it’. I believe the year was 1989. I really don’t care if is heavy. By 1906, bids from six makers were submitted, among them Browning's design, submitted by Colt. BE. The .45 ACP also operates at a relatively low maximum chamber pressure rating of 21,000 psi (145 MPa) (compared to 35,000 psi/240 MPa for 9mm Parabellum and .40 S&W, 37,500 psi/260 MPa for 10mm Auto, 40,000 psi/280 MPa for .357 SIG), which due to a low bolt thrusthelps extend service life of … I am here today thanks to a 1911 45 manufactured in 1917. doubled in size…and since .45 ACP is bigger to start with, it became massive in the end. 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!) I carried one on and off duty and taught with one for over 40 years. 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). You may be kidding some folks but not all my guy. or 45 Auto by SAAMI, is a cartridge designed by John Browning in 1904, for use in his prototype Colt semi-automatic .45 pistol and eventually the M1911 pistol adopted by the United States Army in 1911. In its expanding hollow point form, it is also particularly effective against human targets. The minute variances were not even outside of standard deviation. The .45 ACP (Automatic Colt Pistol) or .45 Auto (11.43×23mm)[1] is a rimless straight-walled handgun cartridge designed by John Moses Browning in 1904, for use in his prototype Colt semi-automatic pistol. ARCHIVED; Armory » Reloading. 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. 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. [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. For those who follow the energy dump and/or hydrostatic shock theories of wounding ballistics, this is ideal. Tracer ammunition was identified by painting the bullet tip red. Today, AR-style weapons are available in 9-millimeter, 10-millimeter, .45 ACP, .40. The larger guns are easier to aim due to a longer sight radius, but they suffer from a weight penalty and low capacity for their size. A main critique of the .45 ACP is the perceived lack of muzzle velocity when compared to other popular calibers like 9×19 or 10mm Auto. good job on the article, Josh. Probably not. Tracer ammunition for the .45 ACP was manufactured by Frankford Arsenal and by Remington Arms. The small size (comparable to a Glock 43 Handgun) combined with no loss of ballistic efficiency make it a potent choice for fans of the .45 ACP. Gun writer, Josh Wayner, reveals the results of his extensive .45 ACP velocity trial, putting the classic caliber to the test. .45 ACP is a very controllable defense round. However, there are occasions when the shorter .45 ACP tubes produce greater velocity than the longer barrels. For years "conventional wisdom" has told us that the .45 ACP cartridge requires a five inch barrel to get the "heavy, fat" bullet up to speed. the “experts” can knock the .45 24/7 but cannot, at this time, that it is the finest pistol cartridge the USA has ever produced. 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. Interesting how u clearly named each weapon and it a exact barrel length, except for the 1911. The 78 Grain Lead-Free Fragmenting Hollow Point bullet travels at 1900 […] Brass cases for each of these cartridges carry the applicable name within the headstamp. When I began this . The Super provides approximately 20% greater velocity than the .45 ACP +P; the Rowland approximately 40% greater velocity than the .45 ACP +P. 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. Now retired, I upgraded to a FNHUSA FNX-45 Tactical with a LWI muzzle brake. We'd … A .45 averages about 11.3”-14.3” penetration. For the most part, the velocity pattern was consistent with barrel length, meaning speed tapered off a bit as the barrels go… The low muzzle velocity also makes the bullet drop over long ranges, making hits more difficult; however, it is important to note that the vast majority of self-defense situations involving handguns typically occur at close ranges. What ballistics aficionados tend to argue is “Stoppng Power” which is the ability of a round to stop your attacker. I carry it cocked and locked, does not print, easy to draw, excellent for CQ, I… Read more », Pointing to the author’s fixation with speed, speed, speed, I call his speed, speed, speed, bet, and raise him the Big A: Accuracy, Accuracy, Accuracy!!! [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. I taught a class in Bristol, Pa. One… Read more », My Shield 45 is a tack driver. 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. 50 Round Box. An average muzzle velocity of 9mm ammunition, that being the energy the bullet leaves the barrel with, is around 1,200 feet per second (commonly abbreviated as fps or ft/s). 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. The two guns were virtually indistinguishable over the chronograph and had a typical variance so low that it could be said the performance was identical. I am currently using an H&G 68 clone and it seems to work fine. The 10mm Auto is a intriguing round in he handgun world. A common theme you will run into when people are discussing the 10mm Auto is that it falls into an awkward weird little crevice somewhere between the performance of a .40 S&W or 9mm and the performance of larger calibers such as the .45 ACP and .357. After the example of the Cavalry, the Army in turn had fielded versions of double-action revolvers in .38 Long Colt. +P means higher pressure, and the loads are several steps above the norm. The resulting .45-caliber cartridge, named the .45 ACP, was similar in performance to the .45 Schofield cartridge, is only slightly less powerful and significantly shorter than the .45 Colt cartridge that the United States Cavalry was using at the time. The SAAMI pressure limit for the .45 ACP is set at 21,000 psi (144.79 MPa) piezo pressure,[13] while Some 45 ACP loads show all the velocity we could ask for. A main critique of the .45 ACP is the perceived lack of muzzle velocity when compared to other popular calibers like 9×19 or 10mm Auto. You can push anything to any speed one desires, so long as materials hold together and that might look great! 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. With rifles this can make a difference, especially at long range. I recall that the Washingtonville, NY PD had just been issued the P220. Josh Wayner has been writing in the gun industry for five years. Without a doubt the 7.62x25mm is a superior penetrator. A longer barrel will ALWAYS produce higher muzzle velocity regardless of which s&w m&p is ur bff. The traditional arguments still prevail in some ways. the SAAMI pressure limit for the .45 ACP +P is set at 23,000 psi (158.58 MPa), piezo pressure. 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. The .45 is a fine caliber for a variety of tasks today. Call us at (540) 898-9256, If you have questions. Despite being heavy rounds, .45ACP recoil doesn’t get in its way. Is it the most effective cartridge available today? UGH! Period. The compiled .45 ACP velocity data points are an average of six (6) readings over the Oehler 35P. This is also why more often than not, a +P load gives better performance in a full size pistol such as the M1911 than… Read more ». This test has given me a very good look at the general performance of this old cartridge and helped me to understand what it is and what it isn’t. Due to standard pressure .45 ACP rounds being inherently subsonic when fired from handguns and submachine guns, it is a useful caliber for suppressed weapons to eliminate the sonic boom. The chambering is massively popular all over the country and, at the same time, is subject to nearly endless criticism over why exactly it has survived into our modern era. Suppressors cannot act on a supersonic shock wave continuously generated by a bullet exceeding the 1,087 ft/s (331 m/s) speed of sound at 32 °F (0 °C) ambient cold temperatures, as this shock wave is continuously produced throughout the entire flight path over which the bullet is supersonic, which extends long after it exits the barrel. [12], According to Commission Internationale Permanente pour l'Epreuve des Armes à Feu Portatives rulings, the .45 ACP cartridge case can handle up to 131.000 MPa (18,999.9 psi) Pmax piezo pressure. Today’s state of the art is striker fire but the P220 was and still is a fine pistol. In tests against ballistic gelatin, a 185 grain hollow point traveling at 1,050 feet per second expanded to about .76 inches. 45-ACP Velocity vs Barrel Length. While the .45 ACP went the "heavy and slow" route, the 9mm Luger took the opposite tack by shooting much lighter bullets at a higher velocity. Cartridge Type: HandgunHeight: 0.898\"Width: 0.48\"Average FPS: 937Average Energy: 403Average Gr: 207Recoil: 0.93Power Rank: 3.88 of 7.45 Auto / ACP is the top end pistol cartridge that packs more energy than the 9mm, the 40 S & W, and of course the dinky 380 ACP. In the second round of evaluations in 1910, the Colt design passed the extensive testing with no failures, while the Savage design suffered 37 stoppages or parts failures. Renewing for my carry license I was able to put Five rounds in a 1″ circle from 7′ as fast as I could pull the trigger, under Five seconds. The 225 jacketed soft point .45 Colts compare closely to the full metal jacket round in .45 Auto. I recently bought a Ruger SR1911, VERY well made and VERY accurate. Even my teenage granddaughters enjoy shooting it. It is my opinion that this caliber isn’t going anywhere anytime fast. In a remarkable display of performance, the Lehigh Defense ( www.lehighdefense.com ) .120gr load had a variance of only 29fps across the average velocities from all four barrels!
