This morning I replaced the factory turret with the custom. The range starts at 200 yds. which is my zero and goes to 600 yds. with one revolution and goes to 900 yds with a second revolution. This is calculated to my trajectory and would be different with a different drop chart. I am planning on testing it out this weekend at my hunting camp.
Oh before I forget. I bought two Butler Creek flip open lens covers and the two sizes that fit are #14 for the eye and #43 for the objective. This is for the 6-24x50mm PST. I do not know about the other size scopes. There is a 3/32" space between the Butler Creek and the barrel.
