Re: Crimping ?
.001-.003 should be enough crimp. (That's thousandths)
Measure the case where ther middle of the bullet rests. Then measure where the case edge meets the bullet. For .45 & most Semi-Auto ammo, you need just enough crimp to hold the bullet & have a smooth transition for the round to slide into the chamber. When you slide your finger from bullet down to the case, it should feel smooth. You'll still feel the transition, but not a abrubt edge.
