Components of a modern bottleneck rifle cartridge. Top-to-bottom: Copper-jacketed bullet, smokeless powder granules, rimless brass case, Boxer primer.. Handloading, or reloading, is the practice of making firearm cartridges by manually assembling the individual components (metallic/polymer case, primer, propellant and projectile), rather than purchasing mass-assembled, factory-loaded ...
The .45 ACP, when loaded up to maximum standard pressures (none of these loads were listed as +P) will outperform .40 S&W in most weights. A quick look at the .45 GAP (which is loaded to .45 ACP +P pressures) shows that the 185 grain bullet is pushed to 1090 fps, for 488 ft. lbs. of muzzle energy; .45 ACP +P should be equal to or (since it can use a slightly slower, less dense powder) slightly ...

Speer handloading guidance states that the loads they show should be used only in handguns made specifically for modern smokeless powder. The loads mentioned in No. 10 reloading manual state that they do not exceed 15,000 psi (100 MPa). This is the equivalent of +P loading as normal pressure for the .45 Colt is 14,000 psi (97 MPa). [11]
