I saw a warning for the use of Lilgun in Freedom Arms revolvers. Apparently, the powder was causing flame cutting. Has anyone had a problem like that come-up? How would it's use in rifles compare? I know it is favorite for the 22 Hornet and 221 Fireball users.
I wouldn't expect that to be relevant to rifles. Flame cutting comes from hot high pressure gas exiting the barrel-cylinder gap. It's essentially 65K PSI flowing into std atmospheric pressure all at once. In a rifle barrel, even with that same initial pressure, the gradient is vastly lower than at a revolver cylinder. By the time the bullet leaves the barrel uncorking what pressure is left, it's under 10K PSI if I remember right. Big difference.
(Best guess, of course.)
