I think key is smoothed feed ramps that don't gouge the cartridge case, bullet tip, and and also smoothed mag feed lips so that the cartridge can pop up, out of the mag as the bullet tip on the feed ramp tips the cartridge upwards towards the chamber. Newly manufactured mags, still have a sharp edge on the mag feed lips, that gouge into the cartridge case, and prevent it from tipping upwards.
that's been what i've found. YMMV.
