I am trying to get ready for my first match this fall can you guys give me some pointers .  I am probally going to run the 22 tac optics or tac optics class at my club. I currently have an Ar15 with a 22 conversion, buckmark or 9mm Xd and M3K shotgun. I am currently using bowling pins as practice targets for the rifle and pistol and some steel knock down targets for the shot gun.
Where do you get the timers with the beepers?
How often do you practice for 3 gun?
What are some good drills?
