It's often hard to tell on a revolver as there is usually a lot of extra length in the cylinder bore, and unless a problem is encountered, one usually loads and shoots all of them without pulling them out to notice any anomalies. I always crimp my .44M rounds for my Super Blackhawk, but I only use the TC die on plated bullets (i.e. Berry's or Ranier) as the Lee FC die causes problems for me unless there is a crimping cannelure present (as in the XTP or your hard cast lead bullets, for example). Either way, I don't anticipate any issues in a single shot rifle without crimping so it's a moot point.stumper wrote: ↑Tue Mar 19, 2019 8:02 am In all honesty, we were not planning on crimping. My buddy and I have been loading the 45 colt out of a heavy 7.5 inch barrel blackhawk for about a year now. We have never crimped a round (we are not shooting the hottest loads the round is capable of) and have never experience a bullet moving.
I have lee dies at the moment. I have the space for it on my loader but it is Will's setup so I am not sure why we do not have the crimp. I have actually shot 5 and measured the sixth round with a micrometer and not detected any bullet movement, not to say it could not happen. I have been wanting to spring for a RCBH setup but that will be further down the road.
