Hello all.. im looking for a factory stock and center feed magazine for a Savage model 12 FV short action. Savage ran the serial number and told me it was a Cabelas special run gun. I need a .308 size center feed set up. I believe it is 4.400 center to center screw holes. It also has a little L shaped clip that fits in the back receiver hole to hold it in place. Im stetting this up for a .358 winchester . Please let me know whats out there or if there is another way to feed this. Thanks..
