That's strange. I shot a deer 4 weeks ago with them and the performed perfectly. Blew completely through a buck's ribs and exited low then continued to pass through the lower portion of the hindquarter. Blew huge holes in and out. Even if they failed to open, the fixed blade would still kill the deer provided you make a good shot. That's why I like them, you get the best of both worlds; cut on contact fixed blade with a set of mechanical blades to boot.

Send em to me if you don't want em.
