I have a rem 700 in 308, varmint barrel 26 inches, 20moa base Nikon Buckmaster 4.5-14 x 40 on top 2 inches above the bore center.
I know my scope is high, but I had the same problem with a Nikon 3-9 x 40 that sat very low. I am shooting either 147 grain pmc bronze (bc .401)or 168 grain SMK BTHP (.477 bc). No measurement of muzzle velocity, I use the factory data plus 40fps. I shoot dead on at 100 yards when the target is on the same plane as I am, submoa groups with the best being one ragged hole less than .6 inches in diameter.
Then I go to shoot at 170. At this distance I get up on the hill a bit and the target is 170yds away but 28 feet in elevation below me. This is only a 3.16 degree downward slope. However the bullets hit 2+ inches high at this distance (either cartridge) and I have to aim low to get on target. Cant figure out why. Could it be possible that the bullet is still on it's way up at 100 yards?
