Must be gettin close. Almost double. And we're still got another weapon in three of these four calibers coming: .45-70, .50MG, 12.7 and BB.
Just for the hell of it, here's a list of FO3 weapons available for inclusion (ie: models already made and easy to include) with my prediction of likelyhood of inclusion (High chance, decent chance, poor chance)
