Toby10: Sorry, I didn't realize you were asking for an explanation of MPBR. I thought you were just asking for opinions about the practice.
NdIndy: Good explanation/drawing.
Good points, Leon. The other problem is that all coyotes aren't created equal and there are a lot of five inch coyotes as well. Again, the theory is good but the practice sometimes doesn't hold water. It is definirely more forgiving on big game but I still don't max out the midrange trajectory for all of the same reasons.
