I've been reloading 45ACP using Berry Bullets and have noticed that copper jacketed bullets are usually shown as having a diameter of .451. But I recently bought a box of lead 45ACP SWC and saw that the diameter of the lead bullet was .452.
Can anyone explain why the difference? Any special considerations when reloading that need to be considered? I use a Lee Classic Turret Press and 4 die setup (including the factory crimp die).
Another interesting data point was that it seems the lead cast bullets require a larger charge of the same powder than copper jacketed of the same weight.
Thanks for the help.
