RE: 3/4 inch groups ?
I haven't shot a set of arrows that were that bad yet. And that includes cheap carbons and bent aluminums. Heck I can take the nocks off arrows sometimes with severly underspined arrows. Of course I am talking about target points, not fixed heads. That's a different story.
I think someone was trying to sell thier arrows. Soccor ball sized groups out of a shooting machine seems a bit hard to believe, unless it was at some extreme yardarge or something.
