I've got an older 130 prefix 300 WM that is my main meat gun, it shoots consistent 3/8" groups at 100 yds with 165 gr NBTs. I have several kills in the 300, 400, and 500 yd range. Since I started shooting it I've always had a Leupold VX-II 2-7x33 on it, but I just got a nice Swaro 4-12 Z3 in a deal, and thinking about upgrading the scope. I know it's a consistent shooter with the 165 NBTs, but was thinking about shooting some 208 A-MAXs, since they would be a better LR choice. Thoughts??
