So I have a 722 in 300 Savage, but want to build something lighter. I was thinking of doing it faux-ti style. If I found a takeoff Mtn rifle contour 308 or 30-06 barrel, is there enough meat in the shank to set it back and rechamber to 300 savage? If this wouldn't pan out, and I need to do a full rebarrel, I would rather do a KS contour, I think. Thoughts? Advice? Thanks.
