Killzone Trophy Tip 100 Opening in flght

Have not been hunting in a month. Was going to shoot the three Klillzones I had to practice before going afield with and they all flew horrible and seemed to be opening in flght. I cleaned them out good and made sure they were competely closed no help. Shot a gator and a g3 montec and field point all flew well. Bow looks good. Anyone had this trouble?

How easily do they open by hand? Do they spin true?

Throw them away.

Mine seem very secure when closed. Anyone else had any trouble with these broadheads? I'm 2 for 2 with them and have been happy with the results. Hopefully this is not a problem I don't know about.

I've been more than pleased with mine. Have you shot them into a target before or taken them apart.

Never haven't had any problems whatsoever with them. Bowfool, are they the 2" cut or the Maxx version?

They are 2". They spin true. Yes I have shot them into a Block target. They snap together and seem secure. I tried them out of another bow same result. Never taken apart. Only shot them about a dozen times. Plan to call the company tomorrow.

With them screwed into the arrow can you hit the broadhead against something and the blades stay closed?

I don't know what it could be. They aren't opening in flight, I can pretty much tell you that. I know Cullbuck had issues with the Maxx version flying with his field points. The only thing I could figure that caused his issue was with the cut diameter being bigger, the blades were just high enough to react like a fixed blade out of his bow. Are they ones you've got the same weight as your field points?

This is my third kill with the killzones and I love them so far. I killed this buck last Sunday with the same head I killed a doe with early in bow season. I just put replacement blades on it and put it back in my quiver in the #1 spot. Just put new blades on it again today.
The shot on this buck was 30 yards. I did not get an exit but it really tore him up inside. He only went about 100 yards. Almost the same shot on a 205 lb. buck last year and same results. They do major damage.
