I have a Remington 783 in .223 Rem. At first it was a PITA because the magazine wasn't properly holding the rounds in. So sometimes when you were cycling the action, a round would pop out when it wasn't supposed to and you'd have things like traffic jams of 2 rds in the action opening.
Eventually washing the magazine with detergent in order to make sure it had no grease or oils in there. And I can't remember, but I think I may have ever so slightly increased the bend inward towards each other of the two lips at the top of the magazine, and I haven't had a feeding issue since. It was always a very accurate shooter though.
