30 Carbine a truly viable PDW with new Hornady ammo

I'm guessing sp and hollow point bullets feed good?

I have shot a lot of the WW 110 HPS. They feed 100% from USGI 15 rounders, and almost 100% with USGI 30s (with new springs). 110 R-P JSPs feed 100% for me in both USGI 15s and USGI 30s. I do polish the feed ramp with a craytex dremel point, though.

Fun and easy to polish the feed ramps. Just polish. Do not remove any material. Also polish both sides of the extractor and the bottom of the bolt rim.

Also fun and easy to lube the insides of the mag bodies with Break Free or similar. Updating to the late mag catch helps hold in the 30 rd mags.

The soft point ammo bullet tip is quite soft compared to the FMJ bullet tip. A slick surface helps the feeding. Shooting lots of SP may leave ramp tracks.

Would polishing or lubing the meplats help?
