Thanks for the excellent info. The gun I am looking at is a Missouri built rifle with a 1:66 twist .50 caliber. The stock is beautiful tiger striped maple and appears to be sound with no cracks discernible in the barrel channel or in the lock area. It does have a peculiar brown barrel finish. Not a chocolate brown but a grey/brown. The bore looks very clean. I put my endo scope down it and could find no rust or pitting. The asking price is $200.00, and from what I have read this appears to be a great deal. I'm gonna go for it.
