Just got a new rifle that has a 20moa picatinny rail already installed. Does this mean that if I have a scope with a max elevation of 65moa I will actually get 85moa at the muzzle? If I have my rifle zero'ed at 100 yards, if I am aiming for a target that requires 20moa for my specific load is my scope then going to be at a zero adjustment point(like coming from the factory) then I have the actuall 65moa of elevation still left out of the scope. I am new to using moa's and have never used a base with a angle built it. If I am creating a DOPE card do I have to account for the rail? If so how does it work? If I am shooting at a target lets say 250 yards away and I have it dialed in with 2 and 1/4 moa's on my scope, does that mean my muzzle is actually at 22 1/4 Moa's? Either I am really just over thinking things or I am really confused. I am in the process of deciding a scope and my goal is to do really long range shooting 1500yrds+. I am looking into the Vortex Viper PST
6-24x50 which has 65 or 67(one of the two) moa's of max elevation adjustment, which will get me out to about 1600 give or take. Unless you factor in the 20moa rail which will actually give me 80+ moa's which will get me out to a mile+. Any advise/help would be great!!!
