I have this rifle SN G 956XXX, currently in .243 Cal. This is the full size receiver and not the short action. IN THEORY, this rifle can be converted to most other calibers by changing the barrel, complete bolt, magazine box, follower& spring and bolt stop when necessary. Of course-it does not make sense due to cost but I got the gun cheap and have a 7mm Mag barrel... my only concern is the receiver rails - did Winchester save money by having the magazine box lips regulate the feeding for each caliber without depending on the receiver rails? What mag box, bolt stop and follower number CODE should I be looking for? Yes, I have too much time on my hands but I am interested. Trading the .243 parts for 7 mm mag parts? Maybe... Mel
