Rock Chuck Bullet Swage (later abbreviated RCBS) is a handloading equipment manufacturer operating in Oroville, California. The company originated during the sporting ammunition shortage caused by World War II , became a widely recognized manufacturer of handloading equipment, and has subsequently been purchased by Hodgdon Powder Company .
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 ...
While various bullet weights were used, a typical load for the .45-90 was a powder charge 90 grains (5.8 g) gunpowder (black powder) with a bullet weighing 400 grains (26 g). Such a load would have had a muzzle velocity of around 1,300 ft/s (400 m/s).
While artillery grain dimensions might be several inches or centimeters, the standard grains of military rifle propellant were 0.085 inches (2.2 mm) long and 0.03 inches (0.76 mm) in diameter. The Army identified this military rifle propellant as Pyro DG (for diphenylamine, graphited), and 500 tons per day were manufactured by various plants ...
Keith's original vision called for dual power levels in the .41, a heavy magnum load pushing a 210-grain (14 g) JHP at a muzzle velocity of 1,300–1,400 ft/s (400–430 m/s), and a milder police loading which was to send a 200-grain (13 g) semiwadcutter downrange at around 900 ft/s (270 m/s).

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 ...
What put an end to the 9×25mm Dillon in competition was lowering of the USPSA major power factor from 175 to 165 (160 for IPSC competition) which improved the safety and effectiveness of .38 Super (and later 9x19 "Major") loads to a point that the extra rounds that would fit maximum-allowed length magazines outweighed any muzzle flip advantage ...
