I would have to say that is far from true. There are a few people here who chimed in and said "I did it once by accident and was fortunate enough to put the deer down quickly and recover it" but I'm sure if the truth would be known there are a lot more people out there who have lost deer with this **** than visa versa. As an example last year my father hit a beautiful buck in the neck after his arrow hit an unseen twig and we ended up recovering the deer over a mile away and a month later after it had been eaten by coyotes and gone to waste. Unfortuantely those things happen in real life although you will never see them in videos, so to say that the facts point to it being an effective shot I believe is stretching a bit.
