Small powder charges
I use to think that downloading a large magnum revolver cartridge was a good idea UNTIL I blew up my 500 S&W Performance Center magnum. Used the lightest recommended load of titegroup behind a 370 grain cast bullet. Exactly as specified on the Hogdgon web page. Destroyed the gun. Cylinder wall moved out and slammed into the frame. Recoil was so severe that it cut the heavy frame on my safety glasses neatly in two. It that recoiling gun had hit me anyway other than it actually did I would have had SERIOUS medical problems.
I always wondered if a gun can detonate with a light charge. Now I know! No light charges for me thanks!
