Some weapons i think have a place in Rimworld Vanilla that are 'missing'.

[Snowcaller]

Just a couple of weapons i think would fit in somewhere.

Double barreled shotgun. Before you get the pump action gauge it'd be logical to me to have a double barreled gun available.
Lever action carbine. Again before bolt action rifles having a faster firing less accurate lower damage gun.
Any thoughts?
have both guns available with gunsmithing and the pump and bolt action as offshoot researches.
