Home Forums Hunting & Shooting AR and Tactical Rifles AR Challenge--Part 2?

the timer on my iphone is 4 second delay, and I cannot hear that frequency any longer. I hit start counted 1 1000, 2 1000, 3 1000, 4 1000 and shot the target. I ran out of time so did not shoot the 25 yard deal. I did find that my aimpoint was not zeroed and was shooting to the left. Blue can I count the one hit on the edge of the 50 yard plate? If so 11.67 for 100, 18.03 for 50, 7.98 for 7 yards. Again this is a combination of counting and a timer, its as accurate as I could get without buying a timer, and I spent that money on a new BHW barrel to replace the Noomoreveske.
