I've been a loyal customer of rage mechanical broadheads for 7-8 years. They have been extremely efficient and I hadn't lost a single deer. Every deer I shot was a complete pass-thru. Last year they changed the design from an O ring keeper to a nylon ferrel. Ive shot 3 arrow into 2 deer this week and none penetrated more than 6". Their new design sucks. The ferrels take too much force to break open and rob energy. Unless, and until, they do something different I'm done with them. Anybody else have this problem?
