Snuffer,
I shoot some pretty stout stuff outa mine also. Try some 300 gr stuff with a good charge of lilgun ,H110 or Win296. That'll take some more hide off! HAHAHA Try some lead stuff, 200gr or 250gr with Unique , clays , 231 or some of the other Pistol powders and you'll find this to be a very pleasureable gun to shoot. Velocities under 1000 fps are fun and less expensive to shoot. Ennjoy it!!
