What would cause it to hit high and to the left even with the sight drifted all the way to the left.
The stock could be warped putting pressure on the barrel.
How’s the stock look with the action taken out?
We've tried it in two different stocks it still does the same not my rifle it's a friend's we also switched out barrels on it still the same I'm thinking something to do with the receiverQuote:

A very likely culprit, especially seen on garands for the obvious reason. If this is the case, the fix might be a simple as just "cleaning" up the crown to even up the termination points of the lands. Manson makes a no-lathe crowning tool - here is a link to them at brownellsQuote:

They also sell a "military crowning kit" same kit, 1 cutter, for milsurp style crowns, half the price.
thanks right now I can't get to it as the guy that's helping me with it is heading out on vacation but another thing is that it rocks in the stock with no action series installed where the forward lug is and both of mine do notQuote:

Look through it at a strong light and the bend can be seen directly opposite by the shadow it makes inside the bore. Once you see the shadow that's cast off, rotate back and forth to pare the affected area down.
I just went through the very same thing with a take off no4 barrel.
Next step is to do what BAR says so I can try to save it for something else and learn.....
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?Quote:

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.
I completely missed that part.Quote:

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.
A different method:
Straightening A Barrel - YouTube
I've done a few, but not that way.Quote:
