We have tested these so far in several barrels including standard, 6.03, 6.02 and 6.01 and we so far haven't encountered a single jam. The BB quality is excellent. They feel like any normal BB. There is no oil, dust or chalk-like texture to them. They cannot be chewed up or crushed in pliers either.
