Greetings, I purchased a couple of packs of Rocket Aeroheads "Steelheads" 100 grain but not sure how to afix them to my arrorws (Carbon). I know to screw them on but also some rubber "O" type rings and washers came along with the package. The package mentions something about shooting an overdraw (???) and to shoot with the blades in the closed postion and make sure O-rings fit in the annular groove and around the balde notches before each shot. I haven't the vaguest idea what all this means. It also states to use two O-rings when shooting over 300 ft/sec. Can someone please make heads of tails of this. Thanks and if you have any graphics to who me that would be excellent.

Thanks.
