My own well known opinion of Powerjunks is not to recommend them to ANY hunter.
Now, lets look at a couple of things here. After dressing out hundreds of whitetail over many years I feel I know the anatomy of a whitetail fairly well. Looking at those pics you posted Pete, the entry of that bullet was most definitely NOT "through" the shoulder. Behind the shoulder maybe catching a TINY bit of cartilage at a steep quartering towards MAYBE but for that bullet to enter the rib cage where it did, a deer would have had to dislocate it's shoulder back by several inches. Also, in that first pick, the entry wound with the coin beside it, that right there shows a bullet FAILURE in itself. To create a wound that large in the hide on entry meant violent expansion upon contact of the HIDE. That sir is the pure definition of failure. Had that bullet even touched the shoulder that deer would have been in another county with a severely blown out shoulder and probably dying from an infection or predators.
Did the deer die? Yep by pure luck because it was most certainly a bullet failure. One of thousands reported by hunters using powerjunks every year.
