[8] The Colt pistol was adopted as the Model 1911. 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. 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. 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. A few dollars can be saved buying components in bulk; however. The .45 ACP is an effective combat pistol cartridge that combines accuracy and stopping power for use against human targets. Choose the .451 diameter Pistol Bullet that's right for YOU. A database of .45 acp handloads. The .45 ACP handguns ranked last, largely due to increased recoil. [14] A factor rated by the recent FBI testing was accuracy and time to recover. The cartridge/pistol combination was quite successful but not satisfactory for U.S. military purposes. 1-16" Winchester. This is a common practice for updating older cartridges to match the better quality of materials and workmanship in modern firearms.[19]. 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. [14], Because of its large diameter and straight-walled design, the .45 ACP geometry is the highest power-per-pressure production, repeating round in existence. Bullets for Reloading 45 ACP The 45 ACP just loves to be handloaded, and doing so is falling-off-a-log easy. Call 262.397.8819 to learn more. Once-Fired .45 ACP Brass. The downside to the use of .45 ACP in suppressed weapons is that increasing the diameter of the passage through a suppressor decreases the suppressor's efficiency; thus, while .45 ACP is among the most powerful suppressed pistol rounds, it is also one of the loudest. [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. .45 Caliber (.451, .452) Reloading Bullets We have a wide selection of .45 caliber bullets for reloading some of the most popular handgun cartridges in the world, like the .454 Casull, .45 Super, .45 GAP, and of course, .45 ACP which is the caliber of choice for one of the most famous and recognizable pistol designs of all time, the Colt 1911. The correct jacketed bullet diameter is .451" (lead bullets are usually sized to .452"), maximum COL is 1.275" and the MAP limit is 21,000 psi. regulated countries are currently (2016) proof tested at 170.30 MPa (24,700 psi) PE piezo pressure.[10]. Rocky Mountain Reloading is the Best Place to Find Great Deals on Bullets and Cases for Reloading. 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 Â°F (0 Â°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. Add to Wish List. In its expanding hollow point form, it is also particularly effective against human targets. .45 ACP (Accurate Data Edition 3.3 - 2009), .45 ACP (in a Kimber Custom II using ACME coated bullets), .45 ACP +P Reloading Data (23,000 psi) (using Cutting Edge bullets), .45 ACP +P Reloading Data (Alliant BE-86 Powder), .45 ACP - IPSC Heavy-Bullet Major Loads + P (Oregon Trail Handgun Data), .45 ACP - IPSC Major Loads (Oregon Trail Handgun Data), .45 ACP - NRA Bullseye Loads (Oregon Trail Handgun Data), .45 ACP - Standard Loads (Oregon Trail Handgun Data), .45 ACP Automatic in a Colt Gold Cup National Match. Tracer ammunition was identified by painting the bullet tip red. When he created the.45 ACP in 1904-05, it pushed a 200-grain bullet to 900 fps. The author did not personally handload, test fire or chronograph samples of this .45 ACP load during the research and preparation of this article. By 1906, bids from six makers were submitted, among them Browning's design, submitted by Colt. [21], Most ammunition manufacturers also market what are termed "+P" (pronounced "plus P", designating overpressure ammunition) loadings in pistol ammunition, including the .45 ACP. 45 ACP cartridges. Determine the cartridge overall length (COL) for the exact bullet you’re using using a load manual as reference. I have personally loaded and fired (in 1911 pistols) 1/4 million rounds of 45 ACP ammo with cast bullets in the 200 - 240 range and 99% of them with Bullseye powder. The terminology is generally given as ".45 ACP +P" and sometimes, but not always, appears on the headstamp. For 185gr JHP's in the.45 acp I use 7.8 grs of Unique. It was eventually evaluated that the .38-caliber round was significantly less effective in overall stopping-power than the .45 Colt against determined opponents in cases such as the Moro juramentado warriors, who were encountered in the Moro Rebellion. Drawbacks for military use include the cartridge's large size, weight, increased material costs in comparison to the smaller, flatter shooting NATO standard 9×19mm Parabellum cartridge, which uses less powder, brass, and lead per round. Not long ago shooters began to report brass that had a small pistol primer pocket instead of the traditional large, due to the use of a more “green” environment primer. Using bullets from Hornady HP-XTP or HAP, Hornady LRN. If you're unsure, or just want options, check as many boxes as you'd like. Some makers of pistols chambered in .45 ACP do not certify them to use Plus P ammunition. This is because of the higher powers achievable with .45 Super, and +P loads. The .45 ACP has 1.62 mL (25 grains H2O) cartridge case capacity. The cartridge headspaces on the mouth of the case at the L3 datum reference. Choose Options.

For the reloader who wants used 45 ACP brass without the used brass hassle, Capital offers 250-count lots of fully processed 45 ACP casings. This means the cartridge is loaded to a higher maximum pressure level than the original SAAMI cartridge standard, generating higher velocity and more muzzle energy. I also don’t trust Nosler’s load data for the bullet very much. Here you will find load data for some of the most recent cartridges on the market, with more being added each week. Capital Cartridge wants to supply every reloader with quality once-fired brass for reloading projects. This is a significantly large permanent wound cavity for a handgun projectile. 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. Reloading The .45 ACP Part 2: Sixguns. With standard (not extended) single-stack magazines, pistols based on the 1911 design commonly hold 8 rounds or less. 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. Display Modes: Linear Mode. As one would expect, there are plenty of reloading components for the .45 ACP. While slightly decreasing penetration and likewise the chance of hitting a vital organ, a large diameter wound will cause more blood loss. 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. 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. The result from Colt was the Model 1905 and the new .45 ACP cartridge. Cross reference load data between at least two sources, ensure your load falls in the “safe range”. The round was developed due to a lack of stopping power experienced in the Moro Rebellion using the .38 Long Colt. Colt had been working with Browning on a .41 caliber cartridge in 1904, and in 1905, when the Cavalry asked for a .45 caliber equivalent, Colt modified the pistol design to fire an enlarged version of the prototype .41 round. The first production, at Frankford Arsenal, was marked "F A 8 11", for the August 1911 date. 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 +P is set at 23,000 psi (158.58 MPa), piezo pressure. For those who follow the energy dump and/or hydrostatic shock theories of wounding ballistics, this is ideal. *Disclaimer: The load data contained on this site is intended for use with Barnes Bullets. Over time, a series of improved designs were offered, culminating in the adoption in 1911 of the "Cal. [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. 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. After two years of testing, one of the final FBI comments was that services that adopt (or stay with) .40 S&W or .45 ACP did so at the risk of increased recoil and a possible reduction in accuracy as 9 x 19mm with premium quality ammunition had nearly exactly the same performance. Bullet: 185 gr. [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. The inner dimensions of the +P cartridge are different from the standard-pressure cartridge dimensions and thus allows for higher pressures to be safely achieved in the +P cartridge. Plus a wide variety of reloading & shooting accessories, and gun maintenance vises. Gear. Over 60 profiles and grain weights of the shooting industry's Superior Plated Bullets. Bullets from other manufacturers may not produce equivalent pressure or velocities; therefore, it is not recommended that this data be used with components other than as listed. Hornady XTP: Powder: Alliant - Unique: Min Charge: 4.8 gr.

Powder Bul Weight C.O.L. Even though the Auto Rim has a lower maximum pressure than 45ACP, it has more internal capacity. 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). cartridge dimensions. Out of Stock ** ACME Bullet Company manufactures the 45 ACP 185 SWC-NLG Hi Tek Coated bul.. $11.00 . A basic look at handgun cartridge reloading - in this case, .45 ACP. DWM, which submitted two Parabellums chambered in .45 ACP, withdrew from testing after the first round of tests, for unspecified reasons.[8]. 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. If +P loadings are used in firearms not specifically designed for them, they may cause damage to the weapon and injuries to the operator. The Nosler 185gr JHP Custom Competition Bullet (#44847) didn’t work for me because of feeding problems. After successful military trials, it was adopted as the standard chambering for Colt's M1911 pistol. The Super provides approximately 20% greater velocity than the .45 ACP +P; the Rowland approximately 40% greater velocity than the .45 ACP +P. But many modern pistols have adopted the cartridge into double-stacked magazine designs, though this increases the pistol's width. Results of shooting handloads with jacketed bullets in the S&W Model or 1988. Recent testing of the three major police and military calibers by the Federal Bureau of Investigation found that the .45 ACP was no more effective with regard to terminal ballistics than either 9 x 19mm Parabellum or .40 S&W. 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. .45 ACP maximum C.I.P. This produces velocities of 1,050 fps to 1,090 fps from my.45's. SAAMI specifications for 45 acp. 45 ACP 200 SWC-NLG Coated *** Sold Out *** More in Stock Soon.

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. You can hammer these down range @ +P velocities without worrying as the jacket is extremely rugged and thick. 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). Only DWM, Savage, and Colt made the first cut. After the poor performance of the Army's .38 Long Colt pistols evidenced during the Philippine–American War (1899–1902), Thompson insisted on a more capable pistol cartridge.[9]. .45 ACP (Using 230 GR Hornady Bullets) reloading data with 71 loads. .45 ACP reloads must be taper crimped. There is also a reduced likelihood of overpenetration, meaning that it is more likely that the projectile will transfer all of its kinetic energy to the intended target, thus more reliably incapacitating them. The SAAMI pressure limit for the .45 ACP is set at 21,000 psi (144.79 MPa) piezo pressure,[13] while This means that .45 ACP chambered arms in C.I.P. 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. They noted, however, training was critical to make sure a soldier could score a hit in a vulnerable part of the body. ... 45 caliber (451, 454 dia) 45 GAP 185 GDHP 45 GAP 185 TMJ 45 GAP 200 45 Automatic 200 LSWCM 45 Automatic 230 LRN 45 Automatic 185 GDHP 45 Automatic 185 TMJ SWC Apparel, Stickers […] Most .45 suppressors must be fired "wet" (with an ablative medium, usually oil or water) to bring sound levels down to "hearing-safe" (under 140 dB, generally).[20]. Tracer ammunition for the .45 ACP was manufactured by Frankford Arsenal and by Remington Arms. [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. All of my die sets for the .45 ACP are also designed for loading .45 Auto Rim brass, with the latter requiring a roll crimp. It was also perfectly linear with several powders, which doesn’t happen in real life. 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.
