Funny dang thing, my fore end from my Pro Hunter 25-06 bolted right up to my new 460 Katahdin barrel. How did that happen if they take a different fore end? Should I return both barrels to TC since they are obviously tapped incorrectly or what? Please advise. Now maybe that blued older Katahdin barrel required a different fore end or forearm if you willl. But those on the Pro Hunter take the same as any other Pro Hunter frame when attached to the one's I own.
