I know many post have been done about how Muzzy's aren't flying right but I thought to post my problem for advice.

I went to shoot my broadheads for the first time this year since switching to a drop away. My arrows hit 6-8 inches high. I thought I made a mistake and was using a 125 gr field points and 100 gr heads. Turns out I was right. So I switched to 100 field points which hit the same as 125 gr. field points. I even put onn old Allen BH to see how they would fly. They shot higher than my muzzys and they are 125 gr.

Any advice is appreciated. I know next to noth about tuning BH and am pi$$ed that it isn't flying right.

If the left/right is perfect and they are simply flying high then it's a nock point/rest tuning issue. If you have access to level tuning, make sure your arrow is coming off the rest level or at worst case, nock high.

I'm not sure how Rob here does it, but I have had absolutely ZERO luck at getting Muzzy's to fly good at high speeds, say over 285.

download easton's tuning guide. Sounds like a nock point adjustment.
