[QUOTE="Eaglet, post: 497711, member: 3756"] To answer your question with the information you're providing above, we will need to make some assumptions: Let's assume it's a .223 Remignton Let's assume it'll be shooting Bergers VLD 70.0 gr. bullets Let's assume you'll have close to 3000 f/sec muzzle velocity Let's assume you'll be shooting at sea level Let's assume your scope height is 1.8" Then After you optically center the scope in the vertical and horizontal direction, move the turrets downwards about 16.2 MOA to be pretty close to zero at 100 yards. That will leave approximately 46.2 MOA of upward adjustment for long range shooting. Yes you will have enough adjustment(36.6 MOA) for 1000 yards though the bullet would be subsonic. At sea level elevation your max range for supersonic velocities would be about 900 yards and you would need about 29.1 MOA The above calculations are mighty close if everything else is where it's suppose to be. :-) In any event are very close approximations.
