Want to make it interesting, try the 22lr pistols out to 100 yards. Then push those rimfires for all they are worth in a rifle.
It is exciting when you can see the bullet impact in a reactive target (balloon?) with a rainbow trajectory at over 400 yards with a 22lr rifle.
That and you need to pack a sack lunch for the flight time. I prefer a KFC chicken bucket with sides. Take a friend and make it a competition and a lunch.
