A few years back I picked up a Winchester model 94 30 30. I can only put 3 rounds into the tube. Anyone had this exp or know anything about it..I have never taken it down to check as 3 is plenty but I wonder about it.
Pull the screw at the end of the tube, pull out the spring and follower and see what is in there. You may have a plugged tube for some reason like some people do for pump shotguns for migratory birds.
