Are you using the same size target at these ranges? How big is it?
Yeah, it was weird. I could ping the 500 target like three times in a row (granted, it was swinging so I was hitting outer edges), but at 600 I got lost. On a box of 20 rounds I only found the target 3 times ( I thought I only hit twice but my spotter said that I did it a 3rd time. I didn't see it, though). Rifle was an Armalite AR-31 .308 with a Nightforce NXS 5.5-22x56 shooting Sako Super Hammerhead 150gr.
I made the turret changes (per the ballistic app) like I had for 300, 400 and 500, all with good success, but 600 was ellusive for some reason. I have no doubt I'm the weakest link in the "system", my 55-year-old eyes arent what they used to be. Although, in my defense, the wind was whipping pretty good that day...I remember wishing I had brought a jacket with me.
All the targets, I believe, were 4 MOA-size, AR500 steel. The range where I shoot ( Triple C in Cresson, TX) have multiple lanes which have targets ranging from 6-8 MOA down to 2 MOA size, and there?s a target every 100 yards on every lane.
Im going back on Monday to sight-in the Grendel and see how far I can take it out. Will post results afterward.
