I use a leica 1600 to range find, which it does very consistently. Ive pondered the idea of being off but the deviation in distance would have to be large (30-40yds) to account for the difference in drop.
Terrain is what i blamed this on for a good while. At my spot im shooting 500yds, im shooting over a small roll and then over a small bend in the creek. To maintain line of sight i always end up raising my bipod up to the point of instability. I always blamed the high hits on the way the rifle rolls during recoil and maybe the wind climbing the creek bank.
Until yesterday when i shot directly over row crop, with the wind to my back, with cold air and high pressure and still hit about 4" high. I cleaned this rifles barrel tuesday, and re zeroed weds with 15 shots to foul the bore.
I am shooting this bullet quite slow (2580 fps), would i need to tweak B.C.?
