2. Applied just enough crimp to hold the bullet in place
Man that brass just COSTS to much to be crimping it conventionally with each reloading cycle !
If the bullets you're loading, bases wiped clean of any trace of bullet lube are rattling around in fireformed case mouths, you either need larger dia slugs, or a stiffer gummier bullet lube.
You ARE aware that BPCR ammo requires "nose up" storage and transport, particularly in warmer weather ?
If you feel you just HAVE to crimp, get aholt of a Lyman long taper die.
