Let me start by saying this is my first time discussion on this forum. (Hope I'm in the right place) I recently got this rifle, and I'm hoping some if you can help with information on it. This barrel is a beast. The 4 holes on the end go in about ¾" not threaded. I've shown in the pictures, the markings on the barrel. I know Remington started out making, barrel blanks for other manufacturers. My guess is this is a target rifle? I haven't weighed the barrel but guess it's close to 10lbs. Any help would be appreciated, thanks
