I've been experimenting with a few packs of Muzzy 100 grain 4 Blade broadheads and have a few concerns about them:

1. When blades are installed and tip is tightened down there is still more room for it to be tightened, is this normal?

2. When the blades are not installed and tip is on they spin great but as soon as blades are installed and tip is tightened not all spin correctly.

Anyone with any suggestions?
