sorry folks, just finished sniper book on hathcock. not looking for specfics, just generalities. i did quick computations and came up with a trajectory of about 68 feet! seems impossible. sorry for the chapping!
Without knowing what you used as your zero range, I am going to say that you are way off.... 40 MOA is a pretty small amount to be honest....
And trust me, we aren't anywhere close to giving you specifics. We are simply asking for the generalities needed to make a basic estimation. You can't even take a little guess without knowing what bullet you are using, the muzzle velocity, and the zero range of the rifle.
