I ran them through my broadhead tests a while back. Basicly I found them to be a pretty good head. Sharp and reliable. The body tends to squeeze in a bit when shot into plywood and the steel drum, but the head remained intact. For deer I think they would work great. Moose on the other hand would be a problem. I don't recomend any mechanical on game larger than deer, and Moose are really pushing the limits!
