Watching several videos on U-tube about bullet coating. Mostly HBN. It seems as if these guys begin the coating but with little to no follow-up. Some will describe a huge plan to experiment further but not much is heard from them after that initial start. My question is " Well does it work good enough that they don't want to say any more about it or did they find a fly in the ointment that they can't over come with more testing ? All opinions welcome.
