And with it being 6 inches higher than my dialed in correction, now I can see why I have been missing them!
Yea, that would explain a miss. Are you actually still zero'd at 100 with the Berger load? How's your group size at both 100 and at 300?
My program says with a "dead nuts zero" at 100, you should hit about 13" low at 300 without moving the scope adjustments at all.......? I used your velocity and the G1 BC.
Problem with 100 yd zero's is : Are we really exactly dead on at 100.? With a 1.5 sight height, we can be within a 1/2" at 100 and not be truely zero'd until we get out to 150 yds.....something to think about.
Personally, I hate a 100 yd zero. I'll zero at somewhere between 200 and 300 and then let my load tell me the velocity based on shooting drops at 300 and beyond. I trust this more than the cheap chronographs, especially when I can repeat it another day under different conditions. The difference in drop between 300 and 400 yds is a really good indicator of what your real velocity is. Slight changes in BC's don't have much impact until we get further out.
