Slightly off topic, but related to Pettifogger's comment about the 357 Max. (blame him):
I have a Pietta Remington NMA with a .45 Colt (not LC) conversion cylinder and, believe it of not, I am getting gas cutting on the cylinder pin from shooting cowboy loads. Soft steel? I don't know, but it is now a science experiment to see how much it will progress.
