I've shot mechanicals now for about 25 years, never had a failure "almost all were with a 2 blade Gator". That was until this sept..
Last spring I thought I'd try a pack of spitfire maxx heads by NAP for bears up in Alberta. THe spitfire is one of the original mechanical heads and is well spoken for. I shot a buck last fall with one and it went about 50 yards, but I shot it in the heart so any head would have done that.
Well this fall I was after a buck that I had been watching a couple years and he really blew up this year. I sat every day of the archery season and on the 11th day I finally had a chance at him. The shot was about where I wanted it up front but a little bit high. I found my arrow broke about 3/4 of the way so I knew he had a big nasty 1 3/4" 3 blade in him and couldn't go far.
The next morning we found quite a bit of blood that led to a bed about 150 yards away..an empty bed. Not good.
I looked for him for a couple days listening for magpies and coyotes. And on the 6th day to my total surprise instead of finding a carcass I jumped him and he took a couple bounds cleared a fence and was gone. The deer didn't even look like he had been shot, I was bummed but happy he was alive and healthy. I hunted him hard but he had turned into a prairie deer and was very hard to pattern.
On the 3rd day of rifle season my brother shot him. This is what was found in his off side neck. ;:;banghead
At the shot impact two blades busted off on his scapula and then it angled forward and somehow lodged in on the other side of his neck without killing him. Had the blades not busted or I'd been using a fixed blade with that shot I'm pretty positive I'd have the largest buck of my archery carrier. Instead I get to see it on his wall, tough pill to swallow. But in the end it was I that took the shot and really can't blame the equipment...well kind of..
For you guys that like montec heads, you'd really like the heads by VPA. VPA's are fully MACHINED, from a solid block of tool grade steel. Montecs are cast. Pot metal, poured into a form. Look close and you can see the casting mark.
