Created by former Special Forces veteran Mike Pannone of CTT Solutions, the 15 in 10 Drill tests a shooter's ability to draw effectively and deliver multiple shots accurately at varied distances. It has become one of my regular practice drills because I like how it makes the shooter focus on effective use of essential skills.
Other than the usual, you'll want a spare magazine/speedloader and pouch if your gun holds fewer than 15 rounds.
Shot on an IPSC target with A and C zones. It's five rounds at 20 yards, five at 10 yards and five at five yards. Begin from the holster with hands in front of the body or hanging at the sides. On the start signal, draw and and fire five shots as fast as you can hit. Repeat for each yard line, adding the times together.
As the name implies, the the goal to deliver all 15 rounds to the A zone inside a combined time of 10 seconds- although one C zone hit is permitted at each yardage. As the distance to the target decreases, the shooter must speed up in order to make the 10-second time limit.Hint: If you do not get the 20-yard shots in five seconds or less, making the 10-second time limit is tough.
I suggest starting un-concealed and then work into drawing from concealment as your skill level improves.
