Had a big whitetail that I couldn't get closer than 535 yards from his crossing point on a slew. After about 30 hours of sub zero sitting, and seeing him three times but no shot due to his constant movement, a stroke of luck got me a shot. A hot doe pulled him in to about 200 yards and that was it. Not the long range shot I had anticipated but my best WT so far. Another one for the 6.5-284.
