All revolvers will show flame cutting to on degree or another if they are fired much. Obviously guns chambered for smaller calibers, and firing milder loads will cut less. It's simply a matter of physics. Keep hitting the same place repeatedly with a flame, and you'll eventually leave a mark.

Flame cutting normally goes only so deep- generally a couple thousandths or less, then stops (I have read that the metal becomes hardened from the repeated heat, but can't verify that is the actual reason it stops). Most flame cutting is done within the first few hundred rounds on a new gun.

"Hot" loads in any given standard caliber don't seem to make any difference in the amount of flame cutting done after the intitial cutting. The .357 maximum is the one exception I am aware of. They do make a difference in the amount of wear.
