I've got a Barnett Doa shooting rage broadheads. I missed 2 deer with it this year. Wide open lanes , closet shot was 23 yards. Very little blood and white hair for both cases. Did some research and I guess the rage o rings are made to not have the slots lined up with the blades. I believe mine were lined up. That said I think my crossbow is shooting to fast causing the blades to open up before impact causing me to shot low. Anybody else have this problem or heard of it
