Crimp doesn't hold the bullet: case neck tension is responsible for that specific function.

In 45ACP recommend obtaining a ($20) LEE "U" undersized Carbide sizing die. This will resize your cases to a slightly smaller diameter that will hold the bullets firmly. Then crimp the mouth to .470-.472".

Make sure you bell the case mouth enough to allow fairly easy bullet seating; too little flare will deform most bullet bases when seating, affecting accuracy (bullet base 'steers').
