At one time, I thought about trying to do something to ensure I could recover the same POI after removing the stock when cleaning my Omega (stainless with black composite stock). All I do now is make sure I replace the screws the same way by referencing them to the hands of a clock. It seems like every other cleaning, the screws end up a little different,but I don't really see it affecting accuracy too much. Isn't it safe to say for 100 yards and under, there probably is not going to be enough difference in the POI to effect deer hunting accuracy, beinga six inch circle? For whatever its worth, I happend to check my stock to barrel fit using a five dollar bill (beacuse I am a big spender) and I could only get the bill about halfway in before it got stuck.
