Anyone know anything about these?Just bought a dozen and cant get a Muzzy to fly right.Suggestions?

I use them and I think that they are fantastic shafts/arrows. Make sure that you spin each shaft with broadhead on to see which ones are and are not straight.

Your bow may needed tuned, put them on a spinner and see if your Muzzy broadheads are stright.
I shoot them out of 65Lbs Black Ice, axis 400 28 3/4 inch with a 85 gr. thunderhead and they shoot great, My broadheads group right with my field points, one pin good for 10 to 30 yards and I can shoot nock off out to 30 yards

Shouldnt have a problem with the arrows, as long as they are cut straight and square. Like mentioned before spin them and see if your broadheads are wobbleing. I dont care what arrow you have if its got a wobble to it, it wont shoot straight.

Thanks alot guys!
