I shoot a Rem 700 long range 300 WM with a 24" 1x10" Proof barrel, H1000, Nosler Accubond LR 190 grain bullets. I tried a ladder test at 400 yds (max our range has) but the mirage was bad enough I couldn't see the holes, and there was enough shooting going on besides me, I just couldn't go down after every shot, so I just got done with a 300 yard test. Here is a picture of the test. I started at 75.4 with .2 grain increments up to 77.2 I know everyone says to look for the vertical shots placements as well as the speed closeness as they should be together. What does everyone think?
