Any lever action will do it, henry or marlin take your pick. Most bolt actions should do it as well, even if they are clip fed, but a tube might be better.
Are you wanting to mix ammo or just be able to shoot different length shells when you want to? Any bolt action or auto can be loaded manually. I used to shoot shorts out of my model 60 all the time. It just won't cycle the action is all.
Yeah for shooting stuff in town I need to be able to mix and match shorts and LR shotshells and be able to rapid fire.
That's why a semi-auto is basically ruled out as well as anything clip fed.
I'd like a nice lever gun but some of them are damn expensive.
