5744 In 45 Colt Rifle

The .45 Colt was introduced as one of the first cartridges for the Model P Colt Single Action Army revolver.

This cartridge was adopted by the U.S. Army in 1875 and served as their official military handgun cartridge for 17 years.

As originally developed, the .45 Colt was loaded with 40 grains of FFg powder with a 255 grain lead bullet for about 810 FPS.

The .45 Colt has been around for 120 years and still has a loyal following. It has become popular to fire higher pressure loads in modern revolvers such as the Ruger Blackhawk. Firing such loads in the blackpowder revolvers and replicas have caused disastrous results.

The large case capacity of the .45 Colt combined with its low SAAMI Maximum Average Pressure of 14,000 C.U.P produces a cartridge that cannot efficiently utilize most modern smokeless propellants. Accurate Nitro 100 is an excellent choice to produce consistent ballistics at low pressures due to its low bulk density and excellent ignition characteristics.
