I'm kinda lazy when packing for a range trip, but when I take a rifle, it's either a Marlin Camp 9, Puma 357 with a 24" octagon barrel, or a Ruger 10/22 TD.
For me, it depends on which range I am going to. I shoot mostly indoors so if I bring a rifle it's almost always a 22, like my new M&P 15-22, Marlin 39A, or my Winchester 06.
I shoot on my own property, so I'll almost always throw a rifle in the truck even if I only plan to shoot handguns. What that rifle is remains undecided till I grab it, and depends mostly on how I feel that day.
