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 ...
Source(s): Accurate Powder [1] The .221 Remington Fireball (5.7x35mm), often simply referred to as .221 Fireball , is a centerfire cartridge created by Remington Arms Company in 1963 as a special round for use in their experimental single-shot bolt-action pistol , the XP-100 . [ 2 ]
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 ...

[12] Jeff Cooper was impressed enough by the 7mm-08 to give it unqualified support for use in Scout rifles-- "A true Scout comes in .308 or 7mm-08". [13]
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).

It would be accurate to say that the .38 Super exceeds 9mm +P velocities, but not +P+. — Preceding unsigned comment added by 153.90.194.27 ( talk ) 19:55, 23 April 2012 (UTC) [ reply ] 9x19mm +P+ is not a standard, as mentioned in the 9x19mm article, it is a designation used by some manufactures to indicate pressures beyond that of SAAMI +P.
