If I was 30 yard away from an elk, and I knew I had to recover the animal, and I had my PSE Mahove with 120gr broadheads on one side and a 243 with 100gr barnes on the other side of me. I would definatly grab the 243.

I hear all the time about killing different ways, but I think people are complicating things and over thinking it. Your trying to cut off the blood supply with oxygen to the brain by turning it elsewhere, like on the ground. The easiest way to do this is one take out the brain itself. This is high risk. Two, by taking out the main pump, or the main collector of the crucial oxygen. A broadhead can't count on high velocity trama, so has to count on cutting surface area. But the problem is the more surface area, (bigger broadhead), less penetration. So you got to find a match to your game and right balance. Gun does the same thing but much easier. Probably 10X easier. Again, however picking out the right velocity with the right mass to achieve a finite penetration. What are you trying to achieve? Your trying to cut off oxygen, in the blood from reaching the brain. But now, your chances are much better and you task so much easier. You can cause much more trama to other vital organs causing much more loss of blood to the brain.
