on everything you reload...........for consistency.

it's so nice to be able to set the seating depth separately from seating.

I crimp only those that absolutely require it. Relvolver rounds such as .44 mag etc. 30-30 does when used in tubular magazines. In rifle most don't until you get to the heavy kickers.

Taper crimp the auto pistol rounds, roll crimp the revolver and tube mag rounds, and don't waste your time crimping the rest.

The only cartridges I've tried the Factory crimp on are bottlenecked pistol cartridges like the
.44-40. It made all the difference. Using the roll crimp die I could not prevent the bullet from being pushed back into the case. I would recommend it for any of these cartridges especially if loaded in a tubluar magazine.

The redding profile crimp brought real uniformity to my .44 mag loads. The ES was cut in half and I've never had a problem with bullet jump.

There are four rules for crimping:

1. Taper crimp auto pistol ammunition (.45 ACP, 9mm, etc.)

2. Factory crimp heavy revolver loads (.357, .44 Mag, .45 Colt +Ps)

3. Factory crimp rounds for tublar magazines (.30-30, etc.)

4. Don't crimp anything else UNLESS you've tried everything else and can't get it to shoot right.
