    Scope adjustment question

    So I never really thought about this before till today. I have a Bushnell 3200 10x40 scope on my .308. The clicks on the turrets move the impact of the round 1/4" at 100 yards. What would one click move it at 200, 300, 400 yards and so on. May be a dumb question but I don't know the answer.

    The math would be 1/2" at 200 yards and 1" at 400 yards...not sure the calc for 300 yards...probably 3/4"...

    oh so the math, sorry I believe is every 100 yards is +1/4" ... from the base 100 yards...someone can correct me if I'm wrong, but I believe that's the calculation...

      That's correct. 1/4" per hundred yards.

        You really need to check it to see if its moving .25" at 100, .25 MOA, or some deviation therefrom. .25 MOA is not .25" at 100. 1 MOA is 1.047" at 100 yards. Doesn't seem like a lot of difference but it adds up the more dope you have dialed. Take a big piece of paper (maybe 35-40" or so tall) and put it up at 100 yards. Make a spot to shoot at toward the bottom of the paper. Shoot a group then dial up 30 MOA. Shoot a group again while still aiming at the same spot. Measure the distance between the 2 groups and see what the adjustments really come out to be.

        Typically the math is 1" at 100 is 2" at 200, 10" at 1000, etc.
