Magnus broadheads are whistling?

[upatree]

I was shooting some new Magnus II 4 blades today and everyone made a whistle when shot. They are the vented ones so I would think that is where the whistle is coming from. I wanted to shoot these for the season and now I an starting to second guess them only because of the noise. Should I be worried?

Oh, they shot great!

Those are some great flying heads.  The whistle is not the vents, occasionally for whatever reason the bleeder slot can whistle.

Smear a little Chapstick into the bleeder slot right in front of the bleeder blade (after the bleeder is already installed) and it will stop.

Thanks for the advice.

what tune?    "Kill da Wabbit"??

upatree... good advice from Slowbow! I most often use a little Duco on the bleeder slot. Prevents any noise that could occur and keeps the bleeder honest.

Not difficult to remove the bleeder when you need to.
