horizontal poi shift with distance change
I have seen some discussions, with inconclusive answers.
Vulcan 25, paired with a 4-12x Leupold scope borrowed from my powder burner.
Using 25Gr JSB, MZ 890fps, zeroed @ 25 yards.
With no wind, the poi@100yard will shift to the left about 3moa, fairly consistent.
Anyone has a solution? or should I just live with it.

If you ruled out spiraling ?
Sounds like horezontal or some call it canting error.
To check you could zero at 10 yards then shoot at 50 yards and 100 yards.
If at 50 yards you slightly to the left and at 100 u have about twice the error to the left, then.
You can try and add a paper shim in the back scope ring, on it’s left side.
See if that helps ….. I had a tread on it but it will be useless to see without the pichures.
Dang, PhotoFuckit ?…
If so they could be alignment issue with the barrel mounting system with the scope rail.
But most of which can be solve with burris signature zee rings.

Could be a bent barrel IMHO
Don’t know if you can turn the barrel.
If you can and the shifting changes direction accordingly then definetively you have a bent barrel.
