Been shooting them since they have came out. Up till this past year I have not lost one animal with them. That includes deer, hogs, coyotes, bear and a near world record Catalina Ram. I have taken over 40 deer with them and all possible shots to test their prowess on all angles.
None of the deer told me that one angle was better or worse than another!!!!
Great penetration, always expanded, and after a touch up on the blades with a moon stone, they were good to go again!!! I'm cheap like that. I prefer to resharpen them and reuse and have yet to see different. I shot a doe with one this past season and I feel that I went over the near lung and took out the far one and lodged in the far shoulder socket. No exit wound. Found her several days later later in a neighbors pond, dead.
Only animal not taken home same day after the shot.
