Bipod POI shift

[Weldor]

Anyone experience poi shift from bipod to resting on bags? I was out shooting the other day, friend has a rem 700 20" 308. When he was using the bipod good groups under moa at 100. When he shot of the bags his groups were still tight but shifted high and left about a moa. Took it off the bags and folded the bipod down, zero returned to normal?

Sure. When the barrel isn’t properly and sufficiently free-floated.

Zero definitely depends on the position.

When shooting off the bipod, does the shooter press hard into the bipod? That is a technique that can control recoil.

But, groups can open up when switching to bags. The control is lost and the recoil then exploits weaknesses.
