180 Partitions outshoot Gamekings, Pro Hunters and Ballistic Tips in my .300 WM. Think it may have something to do with the base obturating and sealing the bore.

Pretty much seems like a consensus that the 165HPBT kills a lot, big stuff too. I have often though of giving it a go but that BC, which prolly wouldn't matter in a million years, keeps me away.
