Altitude Correction For Steep Shooting Angles
Hi guys. The kids and I went out scouting last night and found a couple of bulls out feeding in a grassy slide at 900 yards. I got to thinking about the conditions and planning the shot (if it was elk rifle season) and began to think about the shooting angle along with the change in altitude that the bullet would experience crossing the canyon. My Kestrel showed 2,050 feet at our shooting position, my phone using "shooter" measured the downhill shooting angle at 13 degrees. Tonight I looked on Google earth for the altitude at the elk's position and it was 1,050 feet.
So, the question: how do you calculate the correct altitude for and shot like this where the altitude will change 1000ft or much more between shooter and target? If using absolute pressure you won't know what the pressure is at the target either. My guess would be that one would take the shooter's altitude and target's altitude (if known) and split the difference? In the case of the elk we were watching, would the shot altitude be 1,550ft?
A question on the "Shooter" program:
In the example of this elk scenario I put my info into shooter including my altitude and 13 degree look angle. Is "shooter" smart enough to use that 13 degree look angle input and altitude at shooter's position input to figure out the altitude or pressure at the target? If so does it come up with a more accurate "average" altitude that goes into the solution? Thanks!
