I have had the same issue. I was informed by members here that it could be related to the magazine box hieght in relation to the bolt. The fix was placing a small piece of wood on the bottom of the magazine and hitting it with a hammer. This pushed the magazine up just enough so the bolt will pick up the rounds. This is all done with the action out of the stock. If you hit it to hard and it goes to far up just try to hit lightly from the top without bending the lips until the bolt closes. Hope this helps.
