I have a Savage 12FV with a blind box magazine which is attached into the stock and does not stay with the action when the stock is removed. Would this be the staggerfeed or center feed? From the pictures I've seen it seems like it's a staggered feed however I've also heard the staggered feed magazines remain attached to the action and center feed remain attached in the stock. Mine seems to stagger however it stays attached to the stock. This is where the confusion is coming from for me. It's a rifle I purchased new about 2 months ago but it's hard to know how long it was on the shelf for first...
