I got a tub of brass from a friend and found a bag full of shot cases marked 44mag, measured them and they are .501
So I'm thinking of making some shot shells for the 500.
Weighed on case topped off with #8 shot and it weighs 140gn. Thinking a light charge of unique will get it done. Will check it on quick load.
Just wanted to see if anyone has done this yet and has some tips.
