I tend to agree with "what do you have to lose?" It's like when Vicki Ciancirulo (sp?) shot that one moose. The arrow only went in so far, hit the opposite shoulder or leg bone and bounced out but was clearly a fatal heart shot. As soon as she shot and they saw the bull was just going to stand there the outfitter was saying "Shoot it again! Shoot it again!"

I think I'd do the same given the opportunity on any game.
