[QUOTE="dbleyepatches, post: 350534, member: 22696"] I am currently in the process of building my first long range prairie dog rifle. I am going to attempt to reach out to the 1000 yard range with this monster. The rifle is a 22-250 ackley in a Savage BVSS. I purchased a Burris XTR 6 X 24 scope with 79 MOA of adjustment. Now for the question. When I put the rifle information into the various ballistic calculators I find that at 1000 yards the bullet drop should be about 27 MOA with a 300 yard zero (55 grain V-Max, 4000 fps, 0.255 BC). With 79 MOA of adjustment in the scope, I should not need a 20 MOA base at that range right? It looks to me like I should be able to divide the total MOA in half and that should roughly be my up adjustment. With that being said, I should be able to shoot well past 1000 yards with a flat base, I think. I just want to make sure that I am not missing something since this is my first attempt to use target turrets. I guess that I should add that I am going to use Burris Z rings so I hope to get the rifle to zero at 300 yards with no or very little internal adjustment. Thanks in advance. [/QUOTE]
