Thanks Unclenick. I'm fairly new to taper crimping revolver cartridges. My crimp setting may be a bit . . . assertive. (BTW, I'm seating and crimping in one operation).

I'm going to go "back to zero," so to speak, with the crimp adjustment and start over. OAL aside, I think I have it over-crimping.

I rather doubt it has anything to do with brass length for bullet length, or bullet shape (they are all flat tops). OAL is a function of the seater punch setting and the distance between it and the shell holder. Brass or bullet length should have no bearing on it.
