Can some one explain this to me and is it worth doing for a hunting round???
I don't want to get into the compition shooting or anything just get decent groups from my deer rifles

Right now I'm getting right around 1" to 1.25" groups from my 300 XCR... I really haven't tryed any different powders just IMR4350 and really havent shot more than 50 rounds threw this gun... I would like to see .75 or maybe .50 groups...
