I have shot through the shoulder blade with a 160 glue-on Interceptor and this past fall on the St.Jude's hunt at the Paradise I shot a bunkicker buck in the neck and dropped it in it's tracks with a 190 grain. A few years back complete penetration on Caribou , hit ribs coming and going . Several African plains game as well . I usually aim for the elbow bone when broadside as I never hit exactly where I'm aiming . Really I aim for the off side shoulder and rarely hit bone , except ribs which don't usually matter on a whitetail . My favorite heads for many years . my opinion , Fred
