2 questions have ran through my head with this for years.

1. How accurate is one barrel line on staying the same ID? Say dye ultralit to dye ultralite?
2. Has there ever been a post with common barrels and there ID?

I have searched for this before. Never with any luck. I'd rather have a hand full of barrels with different IDs than a freak set. Not a fan of only a small portion of the barrel being swapped out. Idk. Mental thing.
