It's just in alpha stage. Keep trying, and be patient. The consensus that I've heard (although I don't know how true this is. You'll have to ask a Dev) is that the central database server, which holds your character data, is often overloaded, due to the huge amount of people that play this mod. I doubt it is in anyway a client-side problem, as I often have connectivity issues, along with most of the other players. As said before, keep trying to get into servers, and once you're in one, play your heart out.

I agree with making 12 gauge ammo universal, completely. If it's not going to be universal, then, as others have suggested, make the firearms different calibers. There is a such a thing as a 10 gauge and 20 gauge shotguns. I, totally, understand the need for a balance of rarity among the shotguns, however, I cannot curb my frustration when the pure fact is that 12 gauge ammo is 12 gauge ammo. The same goes for .45ACP. Change the revolver to chamber .44 magnum, or some other, common, revolver caliber. If it were .45ACP, I'd be able to put it into my M1911.
