I just ordered a Vortex Viper Gen ii 5x25x50 MOAR for my Tikka Tac A1. I am new to precision shooting but am planning on getting into PRS matches after much practice. I am looking for scope mount recommendations as I am a little confused on if I need a mount with built in moa height. I have heard you need 30 moa to get the best set up for targets over 800 yards but that anything with moa will make zeroing at 100 yards difficult. My range tops at 300 so lots of practice between 100-300 but my goal is to build accuracy out to 800 this year and 1000 next. Any recommendations?
