H.O.R.S.E.
This drill is exactly what it sounds like: you and one or two friends are going to play HORSE. Start at 3 yards, move out as skill levels improve.
The first person in line will shoot a round in a random position on a sheet of paper, or the margins of a target. The second person will try to put their round through the first shooters hole. The third person will attempt the same, then the first person will attempt to put their round through their original shot. Rotate to the next person after each round.
10-10-10
Using a paper plate (or similarly sized target), shoot this drill from 10 yards from the low ready position.
On the start signal, fire 10 rounds into the target. Any shot after 10 seconds or any shot outside the target does not count. 8/10 is the minimum standard.
Always be safe and remember the 4 gun safety rules!
