On a couple of my factory Savages, ones I have swapped barrels on, and swapped back to original caliber, I have noticed that when using my forstner headspace guages, the barrels do not align to their original settings. What I have seen is sometimes a quarter turn difference. The sad thing is, they shot better new.

I wonder what would happen if I just screwed the barrels back on like they came? Nothing could change from the swaps to make them that far off could it?
