Hello all i'm trying to build up my rifle to shoot 1ooo to 1200 yards or so but need help choosing rings and bases for my scope, not sure what base 0 degree or 20 moa and if someone can recommend a good brand. Here are the rifle specs it is a Remington 700 lss 7mm RUM I found a load that seems pretty accurate it is 89 grs. Retumbo with a 180grn. berger bullet the scope I just got is the Vortex viper HS LR 4-16x44. What would be good rings and bases for this setup and do I need 20 moa bases to get to 1200 yards. Thanks for any help offered!
