IMHO outstanding broadhead that I killed MANY deer with back in my vertical bow days. Unfortunately, I never had luck shooting them out of my crossbow, but have since made some changes that may make it possible for me, but in 125gr.
I have used Muzzy broadheads for a very long time.Never liked their 3 blade offerings for flight,but I use their 90 grain 4 blade with a 1" cut religiously. Have taken a pile of Deer with them in my Vertical bow days, so I brought them over to the Horizontal realm, with no complaints.
Out of my Silver Vent,and Aculeus they fly like lasers out to 60 yards and beyond. Exactly like my 100 grain field point.
