Given that info (and similar info which I have read), I think I'm going to strip the poly, and finish the stock as nicely as I can without "customizing" it. This was actually my first centerfire, and I don't anticipate unloading it anytime soon. I will, however, stop short of drilling and tapping it.
And I never did worry too much about ammo availability. For as much as I shoot it, I can keep handloading reformed .30-06 brass 'til I'm blue in the face.
It is nice though, having a classic mil-surp with matching numbers. Good solid rifles.
