I went with SINGLE SHOT & SHOTGUN.
Here in IL it used to be pretty much shotgun only for firearms season. Now it is shotgun, ML and handgun all in one.
I like the single shot because it is really a "do 'em or lose 'em" deal, and puts a little more fair game in it. And by using H&R USHs if there is gonna be a slip up it is most likely going to be on me.
