And given that drum and barrel (when referring to containers) are usually synonyms in English, it's not unreasonable to imagine a non-english speaker confusing the two, remembering that 'barrel' is a term related to guns, and saying '100 round barrel'.
>A barrel is not a unit of measure for rounds. Learn something about what you want to discuss if you want to have any valid point, being clueless and talking is not a good idea.
Actually my whole point is that people should not care about, and not be allowed to own those things...
That said, I've been in the army myself back in the day, I just don't care for guns to keep reading about them 20 years afterwards, or to go read about the different variations on the market.
Nor is english my first language, I read that the shooter used a 100 round barrel, I guessed they mean an attached mechanism (round), or some magazine or something. I know that revolvers have barrels, and those bizarro mob guns in the 20s (tommy guns?).
Still, apparently there's a 20-bullet barrel, how about it?
They were joking, and you're being needlessly hostile. Plus you're wrong on multiple counts. Most of the counter examples are historic, but still.
Yes, barrel is not a unit of rounds, but there are situations where it would be appropriate. Superimposed loading is where multiple rounds are loaded in the same barrel and are fired sequentially. This is a very old idea, but for a modern take on it look up (the now defunct) Metal Storm. Terrifying stuff.
There have been guns with many more barrels than 7 or 8. Volley guns have been made with anywhere from just a few to nearly a hundred barrels. They weren't always big platform mounted monstrosities either. A famous example would be the nock gun: a 7 barrel, shoulder-fired flintlock.
