Thanks guys for all the input. I've probably shot a little over a hundred rounds through this gun. I've changed bases from a leupold two piece to a one piece, I had it floated, and bedded. I think my biggest problem has been that I've let too many people give me too much input. Remington tells me that there's no way I'll get all of the copper out of a barrel. Do you guys agree with that, or do you think it should come completely clean?
