As with most things related to firearms you must take into consideration the caliber and muzzle velocity and bullet weight when selecting your scope mounting hardware Generally speaking a M.O.A of 0 is used for ranges up to 600 yards and a M.O.A. of 20 is used for shots of 600 to a 1,000 + yards. If you want a scientific explanation Google it. I set up my Savage model 93 .17 HMR and a Nikon Prostaff II 4-12 X 40 with mounting hardware with a M.O.A. of 0. I can get groups of less than 1" at 100 yds. and At 72 years old I ain't that good of a shot anymore.
phantom phixer- I thought you were a young buck and didn't know any better but your an old buck and by all rights should know. Look up MOA, then look up Moment of Angle. I think you may find a difference. Never to old to learn.
