But if you research the Muzzy, well there some good info there too...
Muzzy has always worked fine for me for anything in North America. It's just when you get to the extremes on big game animals when you really want to know what is proven.
Below is a little research I did on a Muzzy 145 grain. It speaks for itself. The muzzy was shot out of a 70# Parker Bow, 32 inch draw. It was shot at a piece of cast iron, the head below that was shot the same way, it was a 135 grain head (I'll keep it nameless):
The last piece of cast iron I shotjust wouldn't die, had to shoot it three times. Maybe where you live the deer are steel plated, but mine aren't. I may be one of the few that doesn't take too much stock in what a blade does through steel.
