This is a great head & you will be very happy with it on deer size game. I honestly think mechanicals are great for deer & smaller. The thing to remember with a lot of mechanical heads is that the ferrel is a little weaker due to more of it being taken away to allow the blades to sit in the body & also they require a more kennetic energy to penetrate good. The snyper tends to use less kenetic energy than most since it' s tip starts cutting right away & the blades are open when they enter the hide. This head also leaves a nice entrance hole since the blades actually are at full or near full cutting diameter when they go through the hide.
I also found this head to fly really good & never had a problem with the ones I have tested.
