I have bought another sps varmint. This is a new rifle. The problem is when chambering a round it feels like it gets in a bind. There are scratches on the bullet (scuffs) and the brass is scratced bad. I have inspected but cannot find any burrs. What else could I look att, could it be the box mag (ADL). The spring follower is real easy to push down in the front. Could this putting round in a bind in the magazine? Any advice would be appreciated. Thanks
