Aren't they all used. I'm going to pull the barrel and replace it on my Savage Mod 10 with a new match barrel. Old barrel is a 6.5 Creedmoor 24" 1-8 twist, threaded, fluted. This barrel shot an average group size over four 5 shot groups last week of 4" at 600 yards. I shoot competition so I need to get ever tighter groups and I don't want this factory barrel laying down on me next spring/summer during the season. Question: Would anyone put this "used" barrel on a hunting rifle? The barrel is shooting pretty good groups still and probably has several hundred rounds of life in it before it would give up.
