I, personally, would not change the feed ramp profile in any way, shape or form. I do polish the feed ramps(frame and barrel) on my shooters, and it definitely helps the feeding process. I start with a 320-400 grit paper/cloth on a wood dowel moving fore to aft to get the machine marks(frequently bad horizontal gouges from a dull tool) lessened/gone. Then I use a felt bob on my dremel at low speed with jewelers rouge(red) for the final polishing. I do not change the ramp profile at all, only clean up the rough machine work. If the feed ramp is really rough, it may be slowing the cartridge feeding process down enough that the main spring can not over come it. I would FIRST try a new mainspring, and then go from there if you need to.
