Slytac Training is a "Law Enforcement Officer driven company based out of Southwest Texas" that has some good information, and some amazing targets.
This drill is a drill to be done with friends. It is a twist on the game HORSE, like we used to play on the basketball court. The first shooter will choose a letter or number, or a series of letters/numbers, then try to hit all the shots they claimed to be able to make. Then the second shooter tries to accomplish the same task. Just like in the original game, if you fail and the other succeeds, you receive an H or a strike.
This game can be higher stress than you think, and a lot of fun to boot! Have a good time with some good folks!
