So I bought a new gun, titled. And need some help explaining moa. This is my first long range rifle so I never gave much thought to moa and what it actually means. I'm looking for a 1 piece picatinny scope base. I really like the look of the higher one, 20 moa description says opposed to the shorter mount that is 1 moa. Can anyone help me with what exactly this means? I hear that if you are shooting longer distance to go with the 1 moa mount, but if your sighting in your scope why would that matter? ......confused, thank you in advance for sharing you knowledge.
