Through the course of running some 100k reloads through my .357 Blackhawk I found all the chambers are not the same length. I ran across this recently when loading some Missouri Bullet Co 158 gr LSWC bullets. I found that in order to properly put the crimp behind the front driving band the OAL came out at 1.602 instead of a max 1.590. This did not concern me, but the fact the cylinder became hard to rotate did.
It was discovered the cylinder became hard to turn as the longer rounds were forced forward as they came into line to fire. Funny thing two of the cylinders worked fine. I reduced the OAL to 1.590 and everthing was fine EXCEPT I was crimping into the front driving band and not behind it.
This is not a Ruger problem as it works fine with 1.590. Its just a problem I have with the Missouri bullets.
I could extend the other four cylinders to make them all identical
Or I could use a different bullet. I'm doing a lot of thinking right now.
Is this different chamber length or crimping into the front driving band going to affect accuracy?
WHAT DO YOU GUYS THINK?
