It's possible for a bow to be in tune, and still have flight problems with fixed blades. Fixed blade broadheads often do not fly like bullet points.... if that is what you're looking for, go to mechanicals.

I used to shoot muzzys and loved them, but I had a similar problem once I switched to carbons. Rather than making adjustments between practice and hunting, I switched to a mechanical.

TheGrim Reapers have some similarities with muzzys, like the trocar (bone crushing) tip, only the Reapers have razors in the tip as well for added penetration, and I can assure you, they fly IDENTICAL tobullet points.

Good luck!
