Winchester 94 style guide rails on Mossberg 464

Question for you folks -- is there some sort of work that can be done on the guide rails in order to help feeding? I've always had good success with feeding, even after switching to Ackley Improved. However, from time to time, I get a cartridge that digs into the sharp edges of the guide rails, and sticks in there, rather than popping the rim up through the rails and into the chamber.

I can tell the pieces of brass that got stuck this way, there are obvious gouges in the rim. Can the guide rails have their edges broken slightly, or do they need to remain sharp for proper function? My brain thinks as long as I don't change any geometry, smoother edges/corners seems better. However, I'm a lever rifle new guy, so I thought I'd ask the pros before I go and screw something up royally.

None of the guide rails in my Winchesters are "sharp"... but neither are they rounded... smooth, yes... deburring would be helpful.

That's my thinking as well. I'll give the sharp corners/edges a run through with something fairly fine.
