several decades ago, I used 110 grain HP in a 30/06 on coyotes. Couldn't see much difference between those and 125 Sierra SP. I've sent quite a few HPBT match bullets downrange from 30/06 & 308.
Last fall, I used Nosler 155 HPBT to kill 2 coyotes, a bobcat, and a deer. Overall performance was not optimal. Explosive expansion when it hit bone on the deer and zero expansion on the smaller animals.
I've used the Sierra GK HP in other calibers and it worked as well as any other cup and core bullet.
