i shoot a mathews outback. its 2 years old. its got a muzzy zero effect and i shoot carbon express cx300.
the problem i have is that i cant seem to get my bow to shoot consistent groups with a fixed blade head. i love to shoot 4 blade muzzys but i cant get it tuned. ive tried 3 and 4 blade heads. i ended up shooting expandables because they shoot consistently. any clues on where to start to get back to fixed blades?

I have no clue on how much you know about tuning so forgive me if I insult your inteligence. It could be alot of things. First it could just be you not knowing what your doing, it could be inproper arrow spine, vanes or fletchings could be not be steering enough, possilby getting fletching contact, man there is a ton of things it could be. Your best bet is to go into detail on your exact equiptment and what you have tried to do.

passthru79 is right. There are too many things it could be to just start making blind suggestions. I think your best bet is to download a copy of Easton's Tuning Guide from their website. It shows about basic setups clear up to and including broadhead tuning. It's about erh best and most comprehensive infromational publication you're likely to find.

Have you papertuned your bow?
