I used these both in summer bow shoots an hunting whitetail in northern Indiana. They have killed doe out to 85yards and hold together on impact. I shoot at Mathews vxr28 @83lbs so I wanted a heavy arrow for my western black bear an elk hunts. The stand up to whitetail bucks hope to test them on bears this spring. Only issue I had was knocks were extremely tight to install. Ended up having to shave down the knock a bit.
