Ive never looked too much into bullet performance or post kill condition. I just started looking into it with these hanloaded hornady 117 gr btsp @ 3242. I've killed numerous white tail and some fallow deer out to 300 yards. All never took a step. I've always noticed the little pin hole entrance and have never gotten an exit. If I hadn't gotten lucky and made perfect shots I always wonder about the deer running off. Is this my bullet selection? I just shot a fallow @ 232yds and recovered this bullet. The core was with the jacket but separate. Has this bullet failed?
