I’ve used many different broad heads over the last 28 years:
Bear Razorhead Zwicky Eskimo and Delta both 2 and 4 blade Wensel Woodsman/Woodsman Elite Wensel Razorcap (No longer made) 3 blade SS head similar in size to a Rothaar Snuffer Magnus 4 Blade Zephyr Sasquatch Grizzlystik Sliver Flame XL Grizlystik Maasai Single Bevel
All were screwed onto an arrow that weighed more than five hundred grains, mostly propelled by a 55-65# recurve bow. I used the Silver Flame XL out of my 70# Mathews this Spring, resulted in a dead bird after about three steps.
I had one deer I hit square in the shoulder with a Woodsman. Peeled that needle point straight back got about 6” penetration. Killed the buck but left very little blood. Shot in the evening…We found him a day later but someone else did first and cut his horns off. The last one I shot with a Woodsman thru the. “12 ring” stuck in the ground after going thru and he dropped in sight leaving a blood trail a blind man could follow.
