I killed my first deer with deadhead this year on Oct 31! I was shooting a 49# Firefly Messenger with cedar arrows and deadheads!
They fly great for me and hammered her at 8 yards. Shot grazed the spine and drove down through the lungs and out the lower chest. She ran about 60 yards with a great blood trail and was done.
I have no hesitations shooting deadheads and am considering them for my Canadian black bear hunt this spring.
I would love to find some more so I have some backups!
