I use the simple store bought Easton Power bolts out to my effective range of 30 yards. I tend to bend aluminium arrows pretty quickly just pulling them out of the target.Mr. Miller agreed that in that range they are just fine but his overall view of them was NOT steller. He thought that their weights were inconsistant.
I am sure in the hands of a good shot which I am sorry to say I am not you could sore tighten up your groups with Awshucks/Miller Killers.

Mike.. What did you mean about disipator pad screws and tuning?? All I ever do is crank them down so tight I strip the holes in the pads. Sigh...
