Having perhaps more enthusiasm than money,here is how I feed my 6" M53. .222" bullets are preferred,but sometimes hard to find in my area,in which case I'll use light weight (40 gr) .223's. I'm trying to work up the courage to try the .224" Hornady 36 grain Vmax but will back off on the powder charge while checking to make sure the bullet actually exits the barrel. I anneal .357 magnum cases by standing them in a tuna fish can with water half way up the neck, and play a propane torch on the upper half until cherry red, then tip them over into the water. Interestingly enough, I have better success with nickeled cases than unplated ones. Yeah, I know, counter intuitive. Even then I get about twenty percent failures in case forming, because I don't use forming dies, just a .256 sizer followed by the Jet sizer. I told you I had more enthusiasm than money. But hey, it works. I won't list powder charges, other than to say they come straight out of the older loading manuals.
