I am new to the ELR shooting.... I do know how to shoot and understand MOA basics. I bought a 300PRC precision rifle and just purchased a 4.5-30X56 34mm MRAD ELR scope that is 30MIL. The 300PRC already has a 20MOA rail on it so I'm asking what MOA mount can I buy that will not in a sense bottom out? I'm thinking maybe a 40MOA but I don't want to spend the money unless I'm sure. You know? Can someone please help me out? Thanks!
