Howdy. I tried responding to the other thread, but it kept locking up for some reason. Odd
It sounds like you may need a better taper crimp die to get the case mouths properly ironed back to shape after belling.
I use the Redding Competition Handgun seating dies in .45ACP and in .44mag. Tight bullet fit or not, they appear to do a better job of putting the bullets in straight than anything else I have tried for straight walled cases. They'd better, they're expensive
After seating in a seperate die, I then go back with a seperate crimp operation - taper crimp in the ACP, a roll crimp in the .44 mag.
Besides Redding, Hornady also has a floating bullet seater in their seating dies. I dislike Hornady's expander dies, however, because you can't remove the expander to adjust the diameter.
You can buy Hornady's seating dies separately, and they cost a lot less than the Reddings.
If I was buying for a new caliber, I'd probably buy Redding's pistol dies, then get the Redding Comp Seater die. If Redding didn't make it for the caliber, I'd try the Hornady.
Hope this info is helpful
