It was a downhill shot, through the spine and out behind the opposite shoulder on a mature (100 lb) blacktail doe last week. The arrow didn't pass through. Not a great angle, but I was confident, it was close range and I've had nothing but great luck with the Slick Trick magnums in the past.
These new Trick heads, the Razor Trick and the Grizz Trick have THICK, sharp blades. I would have never guessed this kind of failure. But, here it is. It dropped the doe, but I haven't had blades fall apart like this in a while.
I've made a few spine shots over the years, and never had the blades break up this bad. Especially on such a small animal. I even sent a 2" Vortex MiniMax mech head through the center of a vertebrae on the spine of a muley buck and was still able to sharpen and hunt with that same head again.
Looking at the frags, it looks like the metal is just too brittle - like cast metal. Not enough spring steel in them to bend without breaking. I guess it could just be this one unit, too. I like the concept of this COC head and they look tough enough to shoot through a shipping container, but I wonder if the original design isn't better than this new, funky, screw lock system they've got. Maybe the torque on the screw causes it to dynamite the blades. I dunno, seems a little hokey though.
Keep an eye out for other reviews you come across about these heads.
