So I've been lurking the site for a bit, and as far as I've found, there's no list of the commonly used acronyms. For most of the board, that's probably not a problem, and for a good portion of the acronyms, they aren't hard to figure out, but some are just beyond me.

And I'd rather not start a new thread every time I want to know what an acronym means, or even keep asking every time I see an unfamiliar combination of capital letters, so I'm suggesting that a list of acronyms and their meanings be compiled into a comprehensive list and either pinned somewhere (IE: General Nerf) or attached to an existing thread or document (IE: the new player's guide, or the new member's guide, respectively)

Just a thought. Not trying to tell anyone how to do their job.

Also, what the hell is an RSCB?

All right, I've searched left and right, and I can't find answers elsewhere, so here goes:

I've got an Over-Under Double Shot that won't eject the shells. Any solutions out there? Is this a common issue?
