Actually, on the one I don't want to crow about another officer was present. He was watching a different elk (about 1500 in that bunch) and thought I missed, which technically I did. I saw it drop like a ton of bricks through the scope. He thought I was lost when I started to walk out to it and was surprised to find an elk at the end of my wonderings. We only got two out of 1500. They bunch up horribly.
You don't have to believe if you don't want to.
Oh, I forgot to clarify. This is not about crowing. I brought up the distance to illustrate the effectiveness of the bullet at .308 velocities at that distance. Granted this is about 8,000 ft. ASL. But the cow at 540 was quartered to me and the bullet entered just in front of the shoulder and exited the opposite side, just in front of the last rib. Immediate incapacitation.
