I spent a couple of hours on a KD range trying to figure out a true reduced 300yard zero. Closest I got was about 33 yards. I also shot two targets to show trajectory. Zeroed up at 300 pretty solid then shot the targets at 5, 10, 25, 50, 100, 160, and 200 as a graphic representation of trajectory of M-855 ball fired from a carbine.

Was pretty neat and if one has not done such a actual test, he will be very surprised at the results. Not what one would envision. It also provides a good challenge to those who are anal about shot placement as there is not a real big vertical spread so basically center hold is just fine from a barrel to 300.

Can you post the target, sketch the POIs, or describe the rise/drop from the various zeros?
