[QUOTE="FearNoWind, post: 1165616, member: 50867"] One MOA is equal to 1.047 inches and most shooters simply round that down to one inch. The .047 factor amounts to an error of .47 inches at 1000 yards so it isn't really critical in making sight adjustments. An MOA scope adjustment is typically divided into 1/4 or 1/8 MOA per click segments - depending on the type and quality of the scope. 55 inches at 100 yards is, generally speaking, 58 MOA. So a 1/4 MOA scope turret adjustment requires four clicks to move 1 MOA (232 clicks for 58 MOA) while the 1/8 MOA turret requires eight clicks for 1 MOA (464 clicks for 58 MOA). My recommendations is don't be a "click counter". Just learn to read the turret markings. I can't explain why your calculator converts 24.6 MOA to 258 inches but I'd guess it has to do with the way the data was entered. If you don't have a 20 MOA rail on your rifle I'd suggest you get one, bed it properly and sight your rifle with a 200 yard zero with that installed. That will put your cross hairs much closer to the center of the scope when adjusting for long range. If you rely on the full extent of the scope's ability to adjust to it's full 58 MOA extent you'll be looking through the outer edges of the scopes lens which will put you into the region of less desirable resolution.
