I've got a Remington '03A3 that isn't feeding worth a crap from the magazine. Each round gets caught on the shoulder before it enters the chamber itself. I have to load each round, singly. The bolt catches the round when going forward and strips it from the magazine. As I push the round forward, from the magazine, it looks like it is getting caught on the portion of the action where the receiver marries with the barrel. I know about the cut off switch, and that isn't the issue. I have replaced the follower and magazine spring, and that didn't change anything. My thought is that I need to polish the feed ramp. I'm no gunsmith, so I'm not sure if this is a potential solution. Thanks for the help.
