I just got done playing around at the range with my Blackhawk and 45 ACP cylinder. The things shoots great, but I really have to thumb the cartridges in hard to get them to chamber properly.
I am already using the thinnest brass I can find (R-P), and my taper crimp is around .471, slightly below the spec. Bullet is a 452460 sized .452, fits the throat great.
Any ideas on how to polish these chambers up slightly to get the rounds chambering a bit easier?
