I own a coyote model Winchester in 22-250.  I am having problems with rounds popping out of the magazine prematurely causing the gun to bind up.  When I have 3 or more rounds loaded in the mag and I either fire the gun or just eject a loaded round the next round up in the mag will either pop out when I am pulling the bolt back or when I am pushing the bolt forward.  It actually pops out, so far out in fact that the cartridge is not positioned to be loaded into the chamber.  I have let the warranty lapse on this gun (I have been putting up with this problem for a little while, and finally want to get it taken care of).  Does anyone have any idea what the problem with the magazine could be, and how it might be fixed?  I would GREATLY appreciate any help you guys could offer on this.

Had simalar malfuntion with a Rem 700 in .222, it was a real head scratcher. When I replaced the
follower, the problem seemed to go away.

is the mag spring inserted correctly? and the  follower? maybe something is bent somewhere........
