45 ACP AMMO for Sale

The 45 ACP or .45 ACP Ammo is a straight-walled rimless handgun cartridge developed by John Moses Browning in 1904 to use in his initial Colt semi-automatic gun. After a successful military trial, the cartridge was accepted as the default chambering used in Colt’s M1911 pistol.

The round was designed because of the lack of stopping power observed during the Moro Rebellion in places like Sulu. The ammunition issued, .38 Long Colt, had failed to meet the requirements, leading to an effort to find a more powerful cartridge. This, along with the Thompson-LaGarde tests of 1904, resulted in the Army and the Cavalry determining that at least .45 caliber was required for the new handgun.

The standard military 45 ACP round is a 230-g (14.9 grams) bullet, which can travel around 830 feet per minute (250 milliseconds) from the M1911A1 government-issue pistol. It operates at a slight maximum chamber pressure of 21,000psi (140 MPa), which is lower than the 35,000psi (240 MPa) for 9mm Parabellum, and .40 S&W due to the low thrust of the bolt allows for a longer service life of guns. Because the standard pressure 45 ACP Ammo rounds are subsonic when fired from handguns and submachine guns, they are an excellent caliber for suppressed weapons to reduce the sound boom.

Nowadays, most NATO militaries have sidearms chambered for 9x19mm Parabellum cartridges; however, the efficiency that the 45 ACP cartridge has maintained its popularity with sport shooters of ample caliber, particularly those in the United States. In 1985, the .45 ACP M1911A1 pistol was replaced by the Beretta M9 9mm pistol, the primary weapon for the U.S. military, which was then replaced with the SIG Sauer P320 9 mm pistol in 2017. It was designated M17 to refer to the large-size model and M18 for the compact version.

45 ACP Cartridge Dimension

45 ACP Ammo has 1.62 mL (25 g H₂O) cartridge case capacity.

.45 ACP maximum CIP cartridge dimensions. All sizes are in millimeters (mm).

The typical rifling twist rate of this cartridge can be described as 16 inches (406 millimeters) with six grooves, O land equal .442″ (11.23 mm), O grooves = 45″ (11.43 millimeters) land width equals .147″ (3.73 3 millimeters), as well as the prime, is a large pistol. The headspace of the cartridge is located on the inside of the case at the L3 date reference.

Based on Commission Internationale Permanente pour l’epreuve des armes a feu portatives (CIP) rules, The .45 ACP cartridge case can manage up to 131MPa (19,000 pounds) Pmax piezo pressure. In CIP-controlled countries, every combination of pistol cartridges must be tested to 130% of the maximum CIP pressure to be certified for sale to the public. That means .45 Auto chambered arms in CIP-regulated countries are (2016) tested for proof at 170 MPa (25,000 psi) piezo pressure in PE.

The SAAMI pressure limit of the .45 ACP is set at 21,000 PSI (144.79 MPa) piezo pressure. Likewise, a SAAMI restriction on pressure for .45 ACP +P is set at 23,000 psi (158.58 MPa), the piezo pressure.

.45 ACP Performance

The 45 ACP Ammo is an effective combat pistol cartridge. It is a combination of accuracy and stopping power to be used against human targets. It is relatively light in flash and muzzle blast and also produces a powerful and manageable recoil when used in handguns (made worse by smaller models).

The standard-issue army .45 ACP cartridge contains a bullet weighing 230 grains that travels 830 feet per minute (253 milliseconds) from the government-issued M1911A1 gun and around 995 feet/second (290 milliseconds) firing by the Thompson M1A1 submachine gun. The cartridge is also available in different special rounds with different weights and performance levels.

The cartridge is operating with a relatively small maximum chamber pressure rating at 21,000psi (145 MPa) (compared to 35,000 psi (241 MPa) for 9mm Parabellum, and .40 S&W, 37,500 psi (259 MPa) for 10mm Auto and 40,000 276 MPa to .357 SIG) This is because of the low bolt thrust can help extend the time of service for weapons that it is employed in. Certain manufacturers of pistols that chamber in .45 ACP do not certify the use of plus P ammunition.

Its non-expanding full-metal jacket (FMJ) version 45 ACP Ammo cartridge has earned a reputation for its effectiveness against human targets due to its weighty mass. It also can penetrate tissue profoundly and harm your Central Nervous System. The large 11.5-millimeter diameter makes an extensive permanent wound channel compared to smaller calibers. This could lower blood pressure quickly when vital parts of the circulatory systems are struck.

Its expanded hollow point shape is remarkably efficient against human targets. When tested against ballistic gelatin hollow point, a 185-grain one moving at 1,050 feet per second grew to .76 inches. This vast wounding cavity can be permanently wound by a gun projectile. It is a good choice if you follow the energy dump or hydrostatic shock theories for ballistics that wound.

Although this may decrease penetration, the possibility of hitting an organ that is vital and causing a larger diameter wound is likely to cause more blood loss. Also, there is a lower probability of overpenetration. That means there is a greater chance the projectile will be able to transfer all its energy to the victim, thereby more effectively imprisoning them.

The drawbacks of military use are the cartridge’s size, weight, and higher cost of materials compared to the lighter, shorter firing NATO Standard 9x19mm Parabellum cartridge, which uses less brass, powder, and lead.

A standard 9mm NATO ammunition has a limited ability to penetrate armor, a weakness shared by the 45 ACP Ammo, whose large slow bullet cannot penetrate armor significantly. A low muzzle velocity reduces the impact of the bullet over large distances, which makes hitting more difficult. However, it’s essential to keep in mind that the majority of self-defense incidents with handguns usually take place within close ranges.

Following two decades of tests, one of the most essential FBI remarks was that companies that adopted (or stick using) .40 S&W or .45 ACP Ammo were doing, however, come with the possibility of increased recoil as well as a potential reduction in accuracy, as 9x19mm top quality ammunition offered almost identical performance. One of the factors rated by most recent FBI tests was accuracy and the time required to recover. It was noted that the .45 ACP handguns ranked last primarily due to the increased recoil.

Due to its massive diameter and straight-walled construction, it is the reason that the ACP geometry is an excellent choice for production. ACP design is among the most significant power-per-pressure repeating manufacturing rounds currently available. This is due to the greater power achievable using .45 ACP+P .45 Super and.460 The Rowland loading. Due to the low pressure inherent in the round standard, brakes and compensators have no effect until +P, Super, and Rowland loads are used.

Use in suppressors

The standard high-pressure 45 ACP Ammo rounds fired from submachine guns, and handguns are naturally subsonic. They are one of the strongest pistol calibers used in suppressed weapons because subsonic rounds are less noisy than those fired by supersonic rounds. They create the sound of a compressed shock wave that can be heard as an audible “crack,” a slight sound, and a sonic boom as they fly through the air.

Suppressors decrease their audible “report” by slowing and dispersing the high-speed gas produced by the expanding and burning gunpowder just before it leaves the muzzle, resulting in the muffled “cough.” Suppressors can’t react to a supersonic sound wave generated continuously by a bullet that is greater than 1 87 feet per second (331 milliseconds) velocity of sound when it is at 32 degrees Fahrenheit (0 degree Celsius) ambient temperatures since the shock wave is constantly generated throughout the entire course of flight through which the bullet is supersonic. It extends for a long time after it leaves the barrel.

The drawback to using .45 ACP Ammo in suppressed weapons is that it increases the size of the path through the suppressor and reduces its efficiency of the suppressor even though 45 ACP is among the most potent pistol rounds suppressed by pistol, but it’s also among the loudest. A majority of .45 suppressors need to shoot “wet” (with an ablative medium, which is usually water or oil) to reduce the level of sound to “hearing-safe” (under 140 dB typically)

45 ACP Ammo Magazine Capacity

The capacity of magazines varies based on the model of the firearm. Standard (not prolonged) single-stack magazines and pistols built on the 1911 model typically have a capacity of only 8 rounds. Modern pistols have incorporated the cartridge in double-stacked magazines to boost ammo capacity; however, this can increase the width of the gun’s handle. Drum magazines typically used for submachine guns can hold a maximum capacity of fifty rounds.

Adoption of 45 ACP

Many U.S. tactical police departments continue to use several U.S. police forces that still employ the .45 rounds for pistols. Although high-capacity firearms can be found in 45 ACP, the larger dimensions and length of 45 ACP Ammo signify that the grips of pistols have to be broader and longer than that of a similar pistol with a smaller caliber. This increased grip size could make the pistol difficult for shooters who have smaller hands.

Currently, most NATO militaries are using sidearms designed for the 9x19mm Parabellum cartridge. However, its effectiveness as a .45 ACP cartridge has ensured its popularity among large-caliber shooters, particularly within the United States. Additionally, a select number of police and military units around the globe continue to use firearms that shoot .45 ACP Ammo. In 1985 the .45 ACP M1911A1 pistol was replaced by the Beretta M9 9mm pistol to serve as the primary sidearm for the U.S. military, although some Special Operations units continue to use the M1911A1 and other .45 ACP pistols.
