We shoot a modified version of the AQT (Army Qualification Target) at 25 meters and each stage has 10 rounds fired with varying mag swaps, target shifts, transitions, etc.
Stage 1 (100 yd scale): Standing, 1 mag with 10 rounds, 1 target, 2 min
Stage 2 (200 yd scale): Transition Standing to Sitting, 2 mags with 2/8 rounds, 2 targets, 55 sec
Stage 3 (300 yd scale): Transition Standing to Prone, 2 mags with 2/8 rounds, 3 targets, 65 sec
Stage 4 (400 yd scale): Prone, 1 mag with 10 rounds, 4 targets, 5 min
Stage 3 is considered rapid fire prone, while Stage 4 is considered slow fire prone with additional time provided due to an additional target and all of the targets being scaled for 400 yd (actual target size on paper is 1"x1", so at 25 yds, that's 4 MOA) instead of 300 yd.
You can bring any rifle you want. Bolts and tubes are a little more challenging in Stages 2 and 3, but there have been shooters who qualified expert (210+ out of 250) on the AQT with a bolt. Centerfires are also welcome, though the majority of shooters bring .22s because you'll go through 400+ rounds in the weekend - many will bring both and shoot their .22 on Sat then switch to their centerfire on Sun. Like Brian said, even if you bring a bolt and have trouble keeping up on the shorter stages, you'll still learn a lot about marksmanship and your American Heritage - just understand going in that you'll we working that bolt pretty darn quickly and may not always get all your rounds off.
Spots on the line are going quickly, so if you're planning on coming, don't wait until the last minute to sign up, or you may be too late!
