I've been using the silvertips for years now, and I've only lost two deer that I remember. But I have killed numerous deer where I don't find blood or only a small amount of blood then the blood stops and it would take me a while to find the deer. But it does worry me when it come to a nice deer and the chance of not finding blood or any deer really. It would just really suck to know I just shot a really nice buck and can't find it, thats numerous nights of no sleep and questioning your self.
