Is it ADL or BDL. If it’s BDL it’s got a hinged floorplate. and by chance if its been removed And then replaced upside down it will do just what your talking about. If it’s ADL it has a blind magazine and the spring just sits in the bottom but could have been reversed.
I have had the same problem many years back when I was playing almost exclusively with 700's.With the BDL it is simple to drop the floor plate and reverse the spring. With the ADL, you'll have to pull it out of the stock and fiddle with it. It's a solvable problem.
