This is my first post so I’m praying I’m doing this right. I just got a bergara 300prc and a few years ago my preacher gave me 500 rounds of 220gr match king bthp’s to make subs for my 300 black out. I didn’t like em so I put the bullets back and now I think I can use em however I can’t get any powder local except I did find a lb of ramshot mag but I was unable to find anything any data on it does anyone know a good load using 220 grain matchking and ramshot? Or is there a reason it’s not been tested idk about thanks!
