45 ACP loading tip

For maximum case tension on jacketed bullets, you need to be careful to use a tight sizing die and the expander ball should not exceed .450" in diameter.
Also, because the 45 ACP headspaces on the case mouth, only a slight taper crimp should be used. If the dies you use have a roll crimp die, spend a few extra bucks and buy a taper crimp die.
Speaking of taper crimps, I use only enough crimp to keep the bullet in place while the handgun is recoiling. It takes a bit of time (and some shooting) to figure this out. Measure the first cartridge to go in the magazine with a quality (PLEASE don't scrimp when buying reloading equipment) caliper that measures down to .001", shoot all but that one cartridge, then remove it from the magazine and measure it again. You'll know when you got it right.
