Personally, with a steel framed revolver in good shape and in 38spl, I'm not sure you can get enough of a powder of that burn rate in a case that will cause a gun to blow up. Recoil and hit you between the eyes? Sure. Blow up? No. Now, if you were to put a fast burning powder, like say Bullseye or one like that, all bets are off!

I'm thinking that they use SR4756. The reason is ..... because I do! That's as good of logic as most have used here today!

Have fun, be safe.
