If it "ain't" broke, don't fix it is an old adage that get's a lot of play, but it really applies here. You do not need "copper solids" as you say, to kill a deer. Your .308 stoked with 165 gr Nosler BT, Rem. Core-Lok, etc will handle, with authority ANY "tick toter" that this continent has to offer..
