Passed on a fork horned moose at 1000yds, moving across a swamp couldn't get the range until later just before dark, but was beyond my scope adjustment and practice anyway, not this fall though.
Passed on a 9'+ brown bear at 750yds, feeding on a moose kill, I had my daughter with me, my drop chart and practice was only worked on religously to 700yds, beyond that I had inconsistancy with the scope at the outer edge of the adjustment. I could have held over, I knew the extra drop, and as I recall there was a little wind at 9 o'clock that bothered me also. It stacked up too much against me.
This was a very big bear too, probably bigger than the 9'3" squared one Brian and my brother shot up there the year before. If everything would have been right, I would have killed him from there, things were far from right though, for one thing my brother was not with me and I would NOT have went after him alone down there.
I shot my moose at 50' behind the ear this year, second to last day of season, I actually passed on him a couple days earlyer thinking he had too many points, turned out one side was leagel.
Complicated laws up here you realy have to look close and be sure. I passed on about a 55 incher the season before because I couldn't teel how wide he was at the time, had to be 50" or more.
