Caliber .45 shot M15 was an improved survival round loaded with 108 pieces of No. 7 1 ⁄ 2 birdshot, with wadding and a vermilion cardboard disc sealing the casemouth. It was loaded and extracted exactly like the M12 shot cartridge. Caliber .45 tracer M26 (T30) has a red tip. The round was designed as a short-ranged red flare for use in ...
If the bullet velocity is capped at 1,000-Feet Per Second / FPS in order to subdue the noise of firing, then the impact can be improved by increasing the weight of the bullet. The 357 Auto can be loaded with bullets in .358-caliber, while still fitting within the AR-15 COAL of 2.260". Bullet weights are currently available between 225gr-310gr
Headstamp for the .45 Remington-Thompson cartridge. The .45 Remington–Thompson (11.4x25mm) was an experimental firearms cartridge designed by Remington Arms and Auto Ordnance for the Model 1923 Thompson submachine gun, a variant of the Model 1921 with a longer barrel, with the intent of increasing the power and range of the weapon.
The .45 Auto Rim, also known as 11.5x23mmR, is a rimmed cartridge specifically designed to be fired in revolvers originally chambered for the .45 ACP cartridge.

For handgun cartridges, with heavy bullets and light powder charges (a 9×19mm, for example, might use 5 grains (320 mg) of powder, and a 115 grains (7.5 g) bullet), the powder recoil is not a significant force; for a rifle cartridge (a .22-250 Remington, using 40 grains (2.6 g) of powder and a 40 grains (2.6 g) bullet), the powder can be the ...
Heavy-for-caliber pointed (spitzer) bullets with a boattail design have BCs at the higher end of the normal range, whereas lighter bullets with square tails and blunt noses have lower BCs. The 6 mm and 6.5 mm cartridges are probably the most well known for having high BCs and are often used in long range target matches of 300 m (328 yd ...
The 45 Raptor (11.5x46mm) is a rimless centerfire cartridge developed for the AR-10 semi-automatic rifle for medium and large game hunting. Compared to similar big bore cartridges designed for the AR-15 – such as the .450 Bushmaster, .458 SOCOM, and .50 Beowulf – the 45 Raptor offers higher velocity bullets, a flatter shooting trajectory and the ability to reliably feed hollow point ...
