How would you explain the crawler proccing corrosive status then? Anyway I tried testing with lvl 20 Detron Crewman and lvl 20 TarMOA with the same Chroma and the results are

Detron crewman: 9 damage per pellet to shield and 6 damage per pellet to health

TarMOA: 7 damage per tick to shield and 8 damage per tick to health

Anything else I should try?
