My rifle and data from shooter match up perfectly, except around 500yds. Ive tested this many times and the results are always similar. At about 450 my bullet starts hitting high, peaks at about .75-1.25moa above data around 500-525yds, then is spot on from 600+.
Ive gotten by with just using a dope chart built around average air density in my area, but id like to understand why this is happening. What am i missing guys?

Re: Dope inconsistancy
I'd like to know as well. I had a load a few years ago that did the same thing only in reverse. It was low instead of high. Then at 700 it was where it was suppose to be.
This is only one of two things that has ever stumped me in LR shooting. I was using a scope that has always proven to have accurate tracking from 100-1000 yards with every other load and on several rifles.
Long range shooting is a process that ends with a result. Once you start to focus on the result (where the shot goes, how big the group is, what your buck will score, what your match score is, what place you are in...) then you loose the capacity to focus on the process.
I never put the scope on another rifle but ive put different scopes on this same rifle and the "bump" is still there. I considered maybe a B.C., or a scope height problem but tweaking these things still doesnt make up the difference.
