All we did here is lay our mil dot reticles over the two verticle targets. Then fired a round at zero, dialed up 1 mil on the elevation turret and fired another holding the reticle in the SAME spot... and so on.. coming up whole mils until we hit 4 mils. Stopped there since we ran out of target AND mil dot reticles have 4 dots in any direction.
This drill was simply to confirm the elevation turret was correct at one hundred yards.
