Jeff,
I also thought of that. I could probably push to 400-450 yards, provided the wind was dead calm. I think I will limit myself to about 350yds for elk (and hopefully get a big bull at a much closer range).
For a bear hunt coming up in a week, I'll probably limit myself to 350yds as well (not too crazy about crawling into srub oak after a wounded bear!).
For a deer hunt, in mid-October, provided the wind was right, and I had plenty of time for a second or even third shot, I might stretch it to 450 yds.
Again, not shooting long range, unless I need to.
