Bullets don't climb.
Your trajectory curve is going to remain constant so long as your load remains constant. All you can do is vary the launch angle (line of bore).
Then this means you have TWO zero's on your scope? One close where the bullet shoots out relatively "flat" then again down range when the bullet comes back down?
The reason I ponder this is because I am dead on at 50 yards then high at 100. Maybey I am back to dead on on out at 150 175?
This has really peaked my interest and actually is inspiring me to spend more time on the range to tweak this in just right. All part of the fun.
