That is strange. My 300 WSM killed my Antelope dead at 200 with a good exit wound. Entrance right behind shoulder.
The weakness with these should be weak jackets, poorly bonded to the core causing bullet framentation. I wonder what they look like on a 30 yard shot out of a gun shooting >3200fps??
I also kind of wonder if their weaker match jacket makes for good performance at like 800 yards out of something like a 308 with a 180 gr VLD...or if it just punches through...
