The constant is that after getting a good group, I removed my action from the stock. Can't change that. And let's say I cannot make it back to the range before opening day. If either of the following two scenarios occur, do you think I will be dealing with a change in POI?

1) My gun passes the dollar bill test. I remove it form the stock and see absolutely no signs of wear from the stock moving.

2) My gun FAILS the dollar bill test, and there are slight wear marks inside the stock. I install teflon shims per your example. Gun then passes the dollar bill test.
There is a possibility (IMO) that the POI may shift just because your removed the stock or either of the two scenario's. How much that shift might be ???? It will probably be less by just by looking and putting the gun back together than anything. Even if you find polished marks in the barrel channel and then sanded them out - you still might get a POI shift.

If you shim it there might be a good deal of shift. But, once you have it shimmed it should be a lot more consistent.

Shims... the shims are only a temporary fix to the problem once you have the time you will end up fixing the entire problem by sanding out the barrel channel. And with the Omega stock it will need to be done at some point.

Bright side... Once you have it fixed it will all be good... and it will shoot very well.

Okay, it passed the dollar bill test, and there were NO polish marks anywhere in the barrel channel, which I examined very carefully. Keep in mind though that this rifle has only seen about 100 rounds.

Regarding the dollar bill test, it did meet some resistance when inserting it. The ram rod sits VERY close to its corresponding channel, but you can see that there is an infinitesimal gap there, but nonetheless, a gap. That would be an easy fix with the Dremel tool. I noticed that the ramrod is not exactly centered in its channel either, which is why the gap on one side was so small. There were no catches throughout the bill's travel until meeting the first lug. So, given this, along with the fact that I had no polish marks, does the stock still need fixing?

I am thinking you might be good....

This statement converns me just a little bit... Remove the ram rod and try the test again. If the bill just barely gets in there.... think about this - if you put upward pressure on the forearm of the stock would it push on the barrel? If it does you might move POI - but your point is well taken - a bit of light sanding in the channel on the nose of the forearm of the stock would take that away.

The thing you want is when you are shooting and applying upward pressure on the forearm it should not touch the barrel.

Hope all works out well...

Sorry about the confusion. What I mean is that it is tough to get the dollar bill started because the gap is so small, AND you are trying to get the dollar bill to conform to a weird shape when initially inserting it. I've never shot the gun with the ram rod in place, and though I can't look at the gun now, I don't think the forearm of the stock would tough the barrel in a normal bench rest situation. I'll check it out again tonight when I get home.

Thanks for your help!
