If anyone cares, you can make your own custom Maximum Point Blank Range based on what game you are shooting. Just vary the radius on the JBM calculator, and check the box to zero and MPBR.

I think for Coyotes, a radius of 4 inches is about right. You don't want to be more than 2 inches high. For an elk, who cares if you are 4 inches high.
