Re: why do shots drop more when shooting at a small incline at extreme range?
Augustus, i am confused. You are a more experinced shooter, and i assume more skilled shooter, than I, and your knowledge is more valuable than my findings that may never affect my shooting. That said, I am just relaying info. It is there, you are missing two key points.
First is that am talking about the difference between uphill and downhill. You may have understood that, but make sure to use the negative sign in the calculations.
Second point is EXTREME distances. The 375 cheytac is amazing and makes extreme much less extreme compared to varmint cartrige.
So I implore you to try two things: Calculate your 375 at 3000 yards at both uphill and downhill angles of 6degrees, and also try my 223 load with g7 bc of .208 at 2890 fps.
I know how ridiculous 2000 with a 223 sounds, I am just using it as an example to show that at extreme distances things vary between uphill\downhill shots.
(Ballistic FTE predicts 70" difference between 6 and -6degrees for rm 375 rbtat @3400fps at a range of 3000 yards. I thought that was interesting.)
