Been using Muzzys for the last 4 years or so. They generally work well on game but I don’t usually get a whole lot of a blood, but I always have an awful time getting them tuned to fly similar to practice tips. So today I bought a pack of Rage heads, which I used before the Muzzys with mixed results. Shooting a Bowtech Sniper at 65#, total arrow weight comes to about 365gr. Not a super powerful setup but gets the job done. When I was using Rage before they had the O rings, these new ones have the plastic shock collar. Has anyone had experience with these and what are your thoughts? According to Rage the shock collar has better blade retention and takes less energy to open on impact. Not quite sure how that works.
