Been involved with a few short barrelled AR's - 556 exclusively, Velocity loss is incredible - no, I did not chrono the loads, dead on at 25, 12 inches low at 100, 6 inches low at 50.
Not something I was interested in, personally.
You claim that the bullet dropped 6” in 25 yards (between the 25 yard zero mark and 50 yard target). Never mind that a person could literally throw a baseball that distance with a flatter trajectory. You then claim that the bullet dropped another 6” while traveling twice as far (50 yards) even though the bullet is continuing to slow down and should be dropping at a faster rate.
Not saying that you’re lying at all but it defies any experience that I’ve had and defies physics. I think something was wrong with your setup.
