Christine.....nope, can't get off for the Waterman...sounds like a hoot, though.
Nomercy448....a lot of people shoot .22s, since the ammo is a LOT cheaper, and the training works well with rimfires. You are welcome to use centerfire...some folks shoot them both days, or shoot rimfire on Saturday, centerfire on Sunday. Mainly marksmanship training on Saturday, and a lot of AQTs on Sunday, history on both days, of course. If you haven't done an Appleseed, you REALLY need both days. You'll need 400-500 rounds for both days.
