All the technicail specs for the A/C/C is avilable on line at Eastons webb page,
http://www.eastonarchery.com/ you can down load there specs or have them send you a catalog. The A/C/C tend to have very high standards and are very uniform. I believe wieght tolerance run about .05 +/- a dozen or so. I just started shooting these myself and really like them, much more consistant groupings then with the GoldTips I was using. Hope this helps.
