Ok, this might be a dumb question but here it goes. With flame cutting, I have heard the use of slower burning powders cause it, and some say faster burning powders cause it. So which is it? I don't shoot alot of rounds, (each gun maybe 500 rounds a year). Is there anyway that flame cutting can be avoided in my .357's and .44 Magnum? Both of these guns are over thirty five years old, and my .357 has it a bit worse, but I don't put full house loads in it all the time. (can't say what the previous owner used). The cylinder gaps are both within specs.
