POA How much is too much

[Sierra Hunter]

Been working on my shooting, ten shots groups, true 0 and all the things that come with the off season. Where I get to shoot, my target is often 4-8 ft in elevation above from my rifle due to the field undulations. From those more experienced and savvy, I’m curious if this affects my 0 in the grand scheme of things ?

I don't think even 8ft at 100yds will affect things but I also don't know what the practical limit is... my guess is if your not having to adjust your normal flat shooting position then your fine.

I have zeroed rifles in the woods in slightly uneven terrain that made no difference later on at the gun club. If your zeroing your scope just make sure the true horizontal distance is exactly the same as you want to zero at.

Can you expand on that last part, would those two things ever be different?
I’d think in a perfect world my point of aim or intended zero is on the same horizontal plane. BUT if conditions don’t allow, does that make a material difference at further distances if I was forced to zero my rifle at a target 4-8ft above my rifle.

If your using a modern laser rangefinder that calculates angle for you then it will never be an issue.

Again, I dont know what the practical angle limit is but if your target is not on the same horizontal plane as the rifle then the straight line distance (hypotenuse) to the target will be different (longer) than the true horizontal (adjacent) distance. Measure your zero distance with the true horizontal distance.


A=100yds, O = 8ft tall = H is 100.04yds actual distance.... not going to make a practical difference shooting a mere 8ft uphill at 100yds zero distance.
