My brother is coming up fromArkansas for a whitetail huntandasked me this question and I told him I'd try to find out.
He zeroed in a scope on a new single shot slug gun 12 gauge, dead on at 100 yards. The area he did this at was about a 10 degree incline. Where do you think the bullet will impact now on level ground? Close enough that he needs not worry about it?
A 10 deg. difference would be enough to be measureable. I suspect you'd need to get upwards of 25-30 deg. or so to start seeing a measureable difference in trajectory. The closer you get to vertical the closer you get to no drop.
shooting uphill - zeroing scope
