I was at a gun show yesterday and a vendor had a early 99c that was chambered in 308 win. The 308 win was scribed over and above it stamped .358 win. He told me it was rechambered to .358 win. I looked and it was a savage factory barrel. I asked how it shot and he said pretty good, now my question The twist along with diameter of a 308 barrel is this even possible? I am not the sharpest tool in the shed and I keep getting duller everyday haha Thanks
