[QUOTE="flashhole, post: 1147753, member: 21375"] Crimping for revolvers and auto pistols are a bit different. The 41 Mag will be like loading a small 45-70. The revolver bullet will have a crimp grove and the standard is to roll the brass into the crimp groove securing the bullet, thus the name roll crimp. The 41 Mag case has a rim so you want the round to drop into the cylinder without undue resistance and rest on the rim. You need to be careful you don't flare the neck too deep to the extent a roll crimp can't reduce the flare and leave a bulge in the case that would make it difficult to insert the loaded round into the cylinder. The auto pistol works with a taper crimp and essentially forms the brass case around the bullet a significant length of the bullet by comparison to the roll crimp that only impacts the top few thousandths of the case. That being said, I prefer to taper crimp whenever I can. I get excellent results using a taper crimp on my 45-70. [/QUOTE]
