The MPBR is the maximum range at which the bullet rise and drop stays within the vital area of your target. Anyone who has been in the U.S. Army or Marine Corps is familiar with a battlesight zero or improved battlesight zero (BZ0 or IBZ0). The concept for an MPBR or battlesight zero is pretty much the same: zero the rifle so that you get a point of aim that is effective over the longest range.

When choosing ammunition for a particular game animal, the terminal performance of the round you choose is extremely important. Winchester has developed (and trademarked) their CXP (Controlled eXpansion Performance) scale which is used to rate ammunition performance on various types of game. Dangerous game animals, classified as CXP4, are generally thick skinned African game animals such as hippopotamus, rhinoceros, elephant and Cape buffalo, and can weigh anywhere from 1,000 pounds up to 13,000 pounds or more for large male elephants. As such, when hunting these species, you will need to choose your caliber wisely.
Only once in all my years of hunting and in going along with my dad as he hunted have I ever been in a situation where an animal that had been shot made a run for it. I am very thankful for this, as the situation is not one that any hunter wants to be in; not only does it feed into the image of our sport among non-hunters as superfluous and cruel, but no hunter worth the tag wants an animal suffering because of a botched shot. It’s also a terrible waste if the animal cannot be recovered.
