Okay, if semantics are so important! LOL!

I have not have .454 handloads break crimp, but have had factory ammo from a number of manufacturers pull crimp. In fact, one lot of ammo that was regularly pulling crimp tied my FA83 up immediately, whereas my Ruger Redhawk was able to fire four more times before the bullet was out far enough to tie it up. It's a real consideration with rounds as raucous as the .454. Of course one doesn't need to load it so hot...... That is the reason Tim Sundles of Buffalo Bore uses a proprietary crimp on his 360 grain .454 loads -- to safeguard against crimp pull.

I just feel that if one's life is going to depend on the reliability of a tool we use in the field, I want the most fool-proof one of all. I don't think that tool is the FA83. Again, just personal perspective and not an indictment of Freedom Arms. I own and will continue to own FA products, I just stay cognizant of the limitations.
