I don't think I like that. It looks to tight and at least I would say it would shorten the useful life of the case using it. I would go with a little roll crimp myself!
I'm actually doing the seating and crimp in two steps. Seating with my RCBS seating die and crimping with a Redding Profile Crimp Series A die for 45 Colt/454 Casull. I lower the seating plug and back the die up a bit so that it does not crimp at all.xtimberman said:I guessing that you are seating the bullet and rolling the crimp both on the same stroke of the lever. Lately, I've been seating the bullet and rolling the crimp on separate steps on my precision revolver handloads to keep this from happening.
If you want to continue to do both in the same step, I believe that you'll get a more normal-looking roll crimp if you back out your seating plug ~1 turn or so and screw in the whole die ~1/2 turn or so.
These are my bear loads. Definitely not going to be plinking with 'em.m657 said:all technical comments aside....my own experience with 'thumper loads' was just that....& I didn't enjoy them nearly as much as I had anticipated....always had better results moving up in caliber if I wanted more thump....
but that is one of the charms of home-built ammo....Cheers to your experiment!
Full case of Goex behind cast 500 grainer in a 45-70...now there's a thumper I can enjoy.....
