Hi, Aaron. Get to an Appleseed!
You'll get coaching and some history lessons and they'll help YOU zero YOUR rifle. They brought me all the way up to mediocre, and that's an accomplishment close to the Moon landings in degree of difficulty.
Looks like there's one about 3 hours away from Stillwater, in Centerton, AR on Dec 15-16
Typically folks shoot .22LR semi-autos, but you can shoot what ya got, and your CZ Trainer would be fine. I qualified with a CZ-455. Just practice working the bolt in the time it takes to inhale and exhale, you don't have to go any faster than that. You need at least 2 magazines, and practice changing them seated and prone. They gave me lots of advice for running a bolt action in this thread: http://appleseedinfo.org/smf/index.php?topic=26206.0
