This damn thread needs to be shut down.
I was watching some deer in a hay field today at about 440 yards (according to Nikon) and a really nice buck muley appeared out of the creek bottom.
There was just no way to get closer and there was a cross wind blowing from the north that must have started up in Montana and gained speed the whole way here.

I passed on the shot. Not that it was beyond my ability but because I plotted to be in the brush above that creek early the next day and maybe ambush that sucker at under 100 if he came back again to feed.

I thought about this thread when I was making my plan. LOL
