Hey there! I'm dropping a Savage off at my Smith's today actually. A new stainless Criterion barrel is replacing an ER Shaw barrel (standard shank) that is 24" long and chambered in .300 Win Mag. It has a couple "long streaks" where the bluing has worn off. I haven't fired a single shot through it, but the previous owner said it shot very well (forum member). Not sure if this would be what you're looking for, but I can take/send pics if you want.
I have a old model 110 7mm RM barrel that is from a 1970s gun it is not shot out. It is blue I would have go dig it up and scope it if you are interested. $50
