Quick question. Are people still using muskets? Or bolt action rifles? Or even semi or automatic weapons?

Bolt-action is the new trend. Muskets are still around. Automatic weapons are conceptually around, but I don't think anyone has begun producing them yet. I'd say they'll appear a bit further into the RP, as someone dedicates the time to properly develop and mass produce them.
