The one state that is probably less likely to have gun control laws than Idaho is Texas. Today we went out to a public shooting range. It was packed. I saw tons of guns and big shiny belt buckles, just like you would expect. I got to shoot an M4 (.223 rounds), a .270 Winchester, and a 12 gauge shotgun (trap shooting). We had a great time, and my shoulder is a bit sore now.
I would say I did the best with the M4, it had a pistol grip and was almost easier to shoot standing up than it was to try to brace it on something at the bench. I put a bunch of rounds in the target at 50 yards. I did okay with the .270 at 100 yards, but the sights are off and it's kind of hard to compensate, especially when you only have about 8 rounds left to fire.
I've also never gone trap shooting, and that was pretty fun. Makes me want to get a shotgun. I hit about 6 or 7 targets out of 20. Not the best, but not bad for a beginner, either.
