I thought I would mentioned my instance of BB-Hop up jam.

I have a VFC AK74 with a stock VFC hop-up unit PDI-W Hold hop rubber and I discovered I cannot use BioShot 0.30g BBs. They jam almost every shot. I have tries 5 other kinds of weights and brands including 0.30gs from BB Bastard. All others fed perfectly on all hop settings with mags loaded full.

Have no clue why, just doesn't like them.

I have a PDI-W Hold in another gun (an M4) that has a G&P Hop-up unit and the BioShot BBs feed flawlessly at all hop settings.

Could be the combination of the VFC unit with the PDI rubber. Who knows.
