Great info Clark.
Have you ever tested the 357 Blackhawk or known the theoretical strength?
Jason
My Blackhawk is a 45 Colt and I would not run that at the threshold of stickly cases, but after reading your question I looked at a 357 Blackhawk at the gunshow this morning. That is about as beefy as it gets.
The 45 Colt Blackhawk is 0.060" between chambers and the 357 Blackhawk looked more like 0.165" between chambers.
That 357 is much stronger than needed for me to feel confident working up to sticky cases, if I had one.
