I have a used Savage Factory Large Shank SS 6BR Barrel from an F-Class Rifle for sale. The barrel is a very good shooter, only tried 107 SMKs. I am the 2nd owner. It has about 300 rounds through it. I only put 50 through it. It consistently shot 5 in the 1/3 MOA, and that confirms what the first owner told me he was getting using Varget. He bore scoped the barrel when new, and didn't like an area near the muzzle, so he had it cut to around 27.5” and target crowned instead of the Savage 11 degree. Very nice job on the crown. I have been shooting a 6BRX, so this one won't get much shooting time, so it's up for sale. The chamber on this gun is perfect for jamming. Some of the Savage F-Class 6br chambers had way too long a freebore. This one is perfect. $185 shipped to the lower 48.
