How much does incline affect zero on 100-yard range?

[TheHorta]

Moving the range on my property. I think I already know, but would like confirmation from those who really do know…

The new location has a 3-4% down-angle grade from shooting location to 50/100/150 yard targets — I’d estimate the 100-yard is roughly 10-feet +/- below the shooting table level.

I assume there is NO practical POI shift caused by the incline at these short distances? So, if I zero my rifles at 100y that will be identical to if I had done the same zero on a flat range?

Danke schön!

Don't try to mooch my grassy ass. Sounds like you are into some strange kink there buddy.

It will be small. very small. I don't know if it would be measureable...

Looking at old discussions it is 1/10 MOA for 15 degrees incline. So a very crude upper limit would be 1/10 of an MOA (and in reality probably 1/3 or more of that). Using my Kestrel/AB at 5 degrees incline gives me no change.

Don’t you have some fancy schmancy doodat that will figure this out for you? Something nobody else has perhaps

I have my Frank clone, but he’s broken. I think it has Tourette’s. It doesn’t stop swearing at people and all it talks about lately is Deersniper and bombing PayPal HQ.

Weird.
