I just bought a 700 P in 338 Lapua and plan to shoot it out to 1000 or a little farther. I have a Leupy LR scope with 125 MOA of adjustment. Should I go with the 20, 25, or 40 MOA mount? I would like to be able to shoot close range with it also. Also, I am setting up my 700PSS in 308 for medium range. I will keep it under 750 yards, so I am thinking the 20 MOA base for it. It will have a scope with ~65 MOA of adjustment. Will this setup work?
