As mentionned, the catch is the rebarrelling situation. Lloyd Nielsen used to make an adapter which screwed into the receiver, and was itself threaded for installation of any barrel. There have been issues with primary extraction. Not a problem with service ball rounds, but there can be difficulties with handloads. The last season the Cadets used the Sportcos at Connaught, you could hear hammering from the line, as tent pegs, mallets, etc. were used to open the bolts.
The action looks very much like a Remington, but it uses a 3 lug bolt head, which is pinned to the bolt body, like a Savage.
Cat is right on with the pricing. And sometimes they don't move very fast at those prices. The sights alone are worth $150.
