Winchester 1917 way off

it rocks in the stock

That could be it too...really easily. Check the stock fitment first. Don't those have two pillars surrounding the action screws? Is one missing?

If the barrel's bent then just straighten it. It's a little harder than that but...easier than replacing it. More on that later if needed.

So many questions with the rifle presently out of hand.

You swapped out barrels and the problem persists? Is that correct? I would try a cut down GI stock. They are around and not expensive. I had a very nice M1917 with a 2 groove JA mint barrel. It shot great until it heated up at around 40 rounds. Barrel would then climb and bullets were right off the target. Barrel was likely not stressed relieved by the factory. I sold it off for a profit. Sometimes you just move on.

we also switched out barrels

I completely missed that part.

I missed that part too! Now that increases the number of possibilities. Could be the receiver is not trued up or the installer bent the barrels on installation, stock warped, etc., etc. etc... Without pics this thread is like pi**ing into the wind.

Mil-spec barrel evaluation usually involved a "target" consisting of a white background with a vertical black bar on it

A straight barrel will show even sized and shaped reflections of the black line on the lands,

Bent and / or worn barrels reflect distorted versions of the black line.

EMEI / EMER etc. paperwork for general small arms maintenance techniques should provide details.

I've done a few, but not that way.
