HOW DO THEY Compare 44mag. caliber rifles to 45 colt rifles?

Answer 1

I'm not sure what you are asking. The ballistics of the 44 Mag tend to be higher because the allowable pressures of the 44 Mag are higher than the 45 Colt. This is because the 45 Colt was originally a black powder cartridge and smokeless powder ammunition sold today must be useable in any gun that will chamber it - whether it is a first generation Colt Single Action Army or a 2007 Ruger Blackhawk. The 44 Mag wasn't invented until 1955 and was originally a smokeless powder round. Any gun chambered for it is built to handle the higher pressures and thus higher muzzle velocities.

Rifles chambered for .45 Colt are a modern configuration and will handle the higher pressures of modern ammunition however commercially sold ammunition must still meet the limitations discussed above.

If you look at load data for both cartridges you will see the 45 LC can be loaded to higher speed with the same weight bullet. The 454 cassule is a longer version of the 45lc. this protects the old pistols from blowing up with hot cartridges. If you have a newer 45 lc it can pass the 44 mag with proper loaded ammo.

Do not try to hop up the load for a 45 LC to match or exceed a 44 mag the cases are thinner and the guns are made to shoot modern 45 lc ammunition how ever the pressure rating are still much lower than the 44. You can load a 45 colt to match a 44 but it could be your last time loading anything!
