I have used their 357 - 158 XTP HP @ 1500 fps to shoot a whitetail buck. One bullet passed completely through the ribs and the other came to rest in the neck after penetrating 18"+ quartering away. They shot 6-shot groups into almost one ragged hole.
I have used their 10mm - 200 XTP load in my Kimber 1911, although they shot accurately they were either way too hot for my pistol or they had soft primers. My Kimber has full case support and I didn't see any bulging at the case head, but the primers flowed so much that not only did they completely fill in the the gap between the primer and the top of the primer pocket, but the firing pin mark was almost flattened back out. Weird deal, I'll shoot the rest of them in my Ruger Buckeye with the 10mm cylinder.
