All I can foresee from the powder is a dirty barrel and hop-up.
All it really does is that, dirty and slick up the barrel and hop up. For the purpose, I dont' know really why graphite coating is applied to some 0.36g BBs, I'm thinking it's to build up and cover imperfections in the BB surface. As for what the heavier ones like Straight makes are made for, is high powered steel sillhouette shooting in Japan, without any hop up, just straight barrel.... according to legend anyways.
