[QUOTE="thequickad, post: 16104, member: 1228"] This is what I found on the Leupold web-site using their Answer guide: What is the Difference Between the M1 and M3 Riflescopes? The M1 has 1/4 MOA adjustments on both the windage and elevation with a total of 15 MOA per revolution. The M3 has 1 MOA adjustments for elevation with a total of 60 MOA per revolution, It goes from 100yards to a 1000yards with one complete turn of the dial (a military request). and 1/2 MOA for windage with a total of 30 MOA per revolution. The M3 is provided with BDC's (Bullet Drop Compensators) for the .308 (168 gr.-2600 ft./sec.), .223/5.56mm (55gr.-3200 ft./sec.), .300 Winchester Magnum (220gr.-2650 ft./sec.), and .30-06 Springfield (180gr.-2700 ft./sec.). Note: The Mark IV M3-10x40mm is gauged in yards except for the .300 Winchester Magnum, which is gauged in meters. The Vari-X III 3.5-10x40mm Long Range M3 is gauged in meters for the .308 and the .300 Winchester Magnum, and in yards for the .30-06 and the .223 Rem. [/QUOTE]
