Ingwe: that big bugger that I posted the picture of a couple of months ago took a second shot to anchor, and it was at about 10-12 feet. Like you said, there was no problem putting the bullet exactly where I wanted it with the scope at 1.5x. But he wasn't running, either. If he still had enough steam to get up and run, my question is which would have been faster: the scope or the irons.
It really is a flat shooting rifle/cartridge combo, isn't it!
