Guys, have any of you played around with reduced loads in 300 RUM if so what powder / bullet combo are you using. I have about two hundred 220gr MK’s I want to shoot up just for plinking. I don’t have any experience with reduced loads. Will a small fast burning powder charge of even work in such a big case with a heavy bullet. Need some suggestions as far as powder goes? Should I try lighter bullets instead of the 220’s? Or, scrap the whole idea and leave the reduced loads for smaller rifle rounds?
