Setup & Shooting Instructions

This drill is executed with a carbine at 50 yards. The standard drill uses four steel targets which, when I run the drill on my steel, is smaller than a IPSC C-zone. However, it’s probably easier to do it on C-zone since that is what you’ll find on most gun ranges.
Place two steel about 40 yards apart on the ends of the range and angle them toward the shooter. Place the other two in the center about 7 yards apart.
The Loadout
Two (2) 5-round mags
One (1) 10-round mag
Aiming at the far left target, fire five rounds to bolt lock, reload and engage the far right target with five rounds to bolt lock. Reload and finish with both center targets with five and five, respectively.
There are a few reasons for using this number of rounds and the pacing of the reloads.
This drill must also be shot clean to obtain your overall fastest time. So when I run this in a class, students know the next guy could turn on the gas and win if they themselves go too slow. The students are their own worst enemies. So this puts even more pressure on the participants.

On my small steel, I am generally humping 14 seconds for completion. On C-zone targets it should be somewhat easier, so 15 seconds is definitely a good number. Text by Chris CostaText by Chris Costa
