The MPBR distance depends upon how flat your cartridge shoots and how large your quarry is.
You can also find that most of the comprehensive handloading manuals (the Sierra manual is particularly outstanding in this regard) include MPBR information, and the correct zero range to achieve it, in their ballistics table--for every bullet and every muzzle velocity level.
The maximum point-blank range (MPBR) is the farthest distance at which the bullet stays within the vital zone, and the MPBR zero is the range at which you zero the gun to achieve the MPBR for size of the animal you're hunting.
