Tryed 777 out to day. Clean I like clean but anywho 15 grains with a 120 grain Buff bullet was kicking! Shot way over my gong(big steel tank end cut off 3/8 thich and 3 foot a cross) no hang time with that load!! Is it to much for my steel frame gun? I checked her out no beating of anything I could see. So what do you all think?
