Years ago I was also of the understanding that they were only needed for "BIG" game like moose and elk. Then I found out they work just fine on deer sized game and much smaller animals as well. It has been my go to big game bullet in several calibers for 20 years. I shoot others also, and I know there's a lot of other options that work as well. Some of my rifles prefer other bullets accuracy wise, but for just killing stuff, the Partitions just seem to work.
