I gotta say that using the 4 step reloading works wonders for me. I don't worry about crimp when I seat the bullet....that is taken care of in stage 4 where I use a Lee taper crimp die for all my auto rounds.
Lee taper crimp dies are the best money I have spent and I also use them on .223 and .308 Win rifle cartridges!
Hope this helps, Mikey
