Redding Reloading, according to their catalog, offers custom made 3-die sets for the .400 Corbon. [23] Lubricating of the bottleneck case can be avoided when starting with .400 Corbon cases by using a carbide .45 ACP sizing die before using the .400 Corbon sizing die. Using a five-stage progressive reloading press makes this less of a chore.
Lead-alloy bullets used with gunpowder firearms were unsatisfactory at the bullet velocities available from rifles loaded with nitrocellulose propellants such as cordite.By the late 19th century, lead-alloy bullets were being enclosed within a jacket of stronger mild steel or copper alloyed with nickel or zinc to reliably impart stabilizing rotation in rifled barrels.
The .41 AE can be ballistically similar to the .40 S&W, to the point that many reloading manuals suggest using .40 S&W load data in the .41 AE. Original IMI factory cartridges are much higher powered, approaching 10mm levels, pushing a 170 gr (11.02 g) bullet at 1215 ft/s. The .41AE actually outperforms the .40SW by a significant amount.
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 ...
The .40 Super drives a 135 grain bullet to 1,800 feet per second while generating less chamber pressure than the 9x23mm Winchester. With a 200-grain bullet, the .40 Super delivers more foot-pounds of energy at 100 yards than the .45 ACP does at the muzzle. The original plan was to market the .40 Super as the .40 SIG, the big brother to the .357 ...
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 7.62×40mm WT (Wilson Tactical) [2] is based on the 7.62×40mm wildcat cartridge, the shoulder of the WT was moved .003" forward and the throat was made .001" larger to accommodate mass-production tolerances while staying within the tolerance of the original reloading die tooling of the 7.62×40mm.

The original Winchester factory load consisted of a 300-grain (19 g) bullet at 1,420 ft/s (430 m/s) or a 330-grain (21 g) bullet at 1,380 ft/s (420 m/s). [ 1 ] With the introduction of superior cartridges designed for smokeless powder , the .40-72 Winchester became obsolete and was soon dropped from production.
