30 Moa Base 100 Yard Zero - 7 inches; since that was the old zero distance, the trajectory will now be 2. with a Vortex Viper PST II 5-25X50 FFP scope on it, with MOA. With most modern scopes having 80 or more MOA which should get most ammo out last 200, why are Just purchased a Ruger Precision and paired it with a Vortex AMG. If you plan to ever shoot farther a 20 Moa will be handy and will still allow for 100 yard zero with the pst. The two scopes I I’m getting set up for a mile and I’m not sure what to do about my zero. I'll be using a vortex Diamond Back 6-24x50 with 56 Moa of adjustment. Been there. I shoot to 1,000 with only consuming 30 minutes. I keep a 100 yard zero.
