I use bonded 165 in mine. I’ve shot everything from coyote’s which is obviously pretty devastating, Bears, deer, elk, and a moose and they have performed well on all of them. Moose was high shoulder shot, bullet held almost all weight and rested against the opposing skin I’ve had bad luck with some of the fast shooting lighter grain Softpoint bullets blow up on contact. Shot a bear with Winchester whitetail 150s and I think pretty much flattened out on contact leaving the exit size hole upon entry. The bullet shattered and barely even made it into the vitals with a small piece of it luckily severing the artery on his heart otherwise I would’ve had a very angry wounded bear on my hands
