Drill #2...
100 yard rifle drill (My take on the Defoor Performance Rifle Test series... Done with full kit.)
-100 yards, lying on your back, feet towards target, 2 shots
-75 yards, kneel down, fire 2 shots
-50 yards, lie prone, fire 2 shots
-25 yards, fire at targets while continuing to move

I'm using 8"x10" steel plates (x2) as my targets, goal is one shot (or more) per plate to move on, so speed and accuracy is key!

Run to each yardage marker between shots, to add to the difficulty work in planned "malfunctions" and mag changes... You can also bump up to full kit to add an extra challenge to the drill.
