Was pretty impressed at how well I could see hits and misses a few weekends ago at just under 3000 yards with an old henny 4x16
Last summer, a cold front blew through and dropped a little rain. We were camping and shooting ELR, so our targets were up and we were ready to roll before sunrise. It was the best light + air I've ever had for ELR. The target at 2650 yards had knee-high grass in front of it. Even through our cheapo Celestion spotting scope, I could see the grass clearly. Shooting through a Vortex Razor Gen 2, calling the wind was simple. The target was painted white and we could see the stain of the impacts clearly. It's normally not that easy.
