Has anyone used .257 Bear Claw bullets/ammo?

Digging through my ammo stash, I found several boxes of 25/06 115 Bear Claw ammo. IIRC, the Bear Claw has some awesome initial expansion and then claims to hold that as it pushes on through.

Nope haven't had any of them! Athough the 25 06 is on my want list!
Been kinda looking at them lately any info you'd like to share would be appreciated.

I'm not even sure how long I've had this ammo but likely pre-2000. The Nosler Partition of similar age is still consistent and useable and I assume that the Bear Claw bulleted ammo will be also.
I just haven't ever used any Bear Claw bullets so only have advertisement info to go on.
