Used the 150 Ballistic Tip on a good sized bull last year in my 7-08. Bullet angled from middle ribs through vitals and was under the offside scapula. That's something like 32+" of elk. Bull motored 50 yards and was dead when I got to him. He was an older bull in the 7-9 year old range.

I believe a Partition would have made it through the scapula, but may or may not have exited. Either way the result would have been the same. A dead elk.

I've only taken two elk with Ballistic Tips, but they've always performed as advertised. If I were confined the rest of my hunting career to using ballistic tips I wouldn't worry one bit.

And yes, the bull was taken in the heart of grizzly country, and no I have always and only had one log-in name (grin).
