I am trying to use a copper round for this rifle because I purchased my lifetime CA hunting license before I left the state. I get a deer tag for rest of my life there and CA is banning lead bullets in an attempt to save the world. At the moment, this will be my rifle for eastern sierra muleys if I happen to get a tag there this year. Thanks for all the info, I will definitely work on a Berger load after I get the copper load dialed in.
