Have a NIKON monarch 4-16x42 with bdc and have plotted spot on for my round printed it and put it on my mag and still wouldn't take a 600 yard shot on a deer. Must have looked like a tic tac in your 3-9. what ev though. I'm not here to judge, just giving my 2cents . Think it was more luck than anything. I've shoot out to 400 yards regularly with .300 wsm and .243wssm and it still amazes me how much of a factor cross wind can be. where u shooting from a tree stand, gree hand, or bench.
