Called Savage customer service to find out about proof marks on barrels. The answer I got was "well we don't do proof marks." I said "well what is the "x" mark on my barrel for?" Answer. "That's were someone worked on it along the way." "Well what do the other proof marks on barrels mean?" "We don't do proof marks but there are usually marks under the barrel nut on rifles." "Well what are they for....what do they mean?" "It's where someone worked on it along the way."

Gave up at this point.

Anyone know what various proof marks mean?
