Sorry to rain on your parade folks but do you really think you magic bullet really opened up "to the size of a softball"? Look at the facts, Most bullets are .308 or smaller when they leave the barrel. Almost all have ridges left on them from the rifling of the barrel. Upon impact, at anything longer than OH MY GOD close will penetrate (deer) about 2-4 inches before expanding. Remember those ridges, well they are cutting little pieces of flesh bone ect from the animal and throwing them perpendicular to the would chanel (read blood shot). While expanding all the way to at most 2X the Dia, the bullet sheads some (demending on the design) of the lead and throws it from the wound chanel. (I am wrong here but I think most bullets are spinning around 100,000 RPM's). If you are leaving a softball hole then your bullet penetrated TOO FAR. It is causing the most colateral damage during this time and you wasted the bullet on meat instead of vitals. The best shots I have witnessed or made was a 222 to the chest right behind the leg. Entrance would bullet size. Exit wound rib far side less than 2X bullet size. Heart, lungs, and liver looked like red apple sauce. This bullet performed flawlessley. While Doing some calling one morning durring deer season (I really did not want to kill a deer) a Wide 8 walked up to the fence 200yds away and jumped in the field I was at. As I had a 223 with varmit bullets I figured I had 2 choices, one he got a pass (**** NO), two I had to take his head off right at the base of the skull. As he turned to look away from me the bullet struck the back of his neck 2 inches below his skull. There was a CRACK report that came back to be. The bullet exploded on impact and went all of 3 inches in but his spine was missing for 3 inches and he was dead. It all comes down to 1 what you have at the time, 2 what kind of shot you are offered, and 3 knowing what you need. Someone chasing bear in the woods needs to knock em down, Me in West Texas can walk across the field and follow a 300 yd blood trail and see the deer on the other side. I was just drawn for an Elk tag in CO and will be taking Partitions for my 300 RUM. The Swifts shoot better but they dont offer me the penetration I desire for my first elk. If I have a TX heart shot and thats as good as its going to get then I know the Bullet can do its job IF I put it in the right place. the swift would not reach the vitals. I actually prefer SMALL exit wounds overall.
