After a lot of searching on several forums, I still don't have an answer to this question, so I thought I'd ask here.

I shoot 200 grain .45ACP RNFP in my model 625 because the rounded bullet nose decreases my reload times. Chambers on the gun are highly chamfered (think small funnels). I have about 3000 200 grain SWC bullets that I used to use in my 1911s. They do not work well in the 625 because the edges hang up on the chamber mouths. I've done some experimentation with heavy taper crimp at the sharp forward edge of the bullet, and it improves things somewhat - it only takes a bit of wriggling to get the moon-clipped rounds to drop in.

Thus my question - if I apply a heavy roll crimp over the front edge of the bullet, will that round things up enough to prevent the cartridges from hanging up on the chamber entrances? I'm not concerned with the loss of headspace capability at the front of the cartridge - these will be revolver-only. RCBS makes a .45ACP roll crimp die that's fairly inexpensive, so I will probably get one and try it, unless I get some information from you folks that it won't work.

I appreciate any comments.
