In order to be prepared for ANY critter you might encounter at ANY possible range? Why, the Nosler Partition Jacket!

Reason: The front end is a soft, relatively frangible separate bulletthat will expand on light tissue, and at almost any range (impact velocity). The rear partis a tough "solid", so that even if the front core is completely gone, there is the back part which retainssufficient sectional density to continue penetrating far enough to destroy the vital organs.

There MAY be another bullet design out there that will do as well in both expansion and penetration. But I have not yet used one, if they actually exist!
