I have found this thread to very interesting as well... I have a few bows that are all in the 50# range. These bows with 10gpp 15%foc will zip thru a broadside deer or the size of hogs that I normally shoot (100lb or less).
I have been seeing a couple huge barr (castrated) hogs that are hanging out together. I picked up a Big Jim TC 78# with those barr hogs in mind.
As luck would have it my family and I got T-boned by an 18 wheeler that ran a red light. We are all banged up but we will be fine (Lord willing). My shooting as come to a halt as a result of our accident, which really stinks because I pretty much had those barrs number.
I have barred many hogs over the years and they will get huge. I am still a little concerned if I will be under bowed for some of the huge ones.
Hopefully I'll get going again before it starts to get hot and we'll see what a 78# bow will do to the big ones
Be safe and shoot straight!!!
