[QUOTE="Unofficial Gun Addict (UGA), post: 1023479, member: 81139"] Yeah... I hear what you are saying and I do believe that concentricity matters... I just discovered that the Hornady concentricity gage, at least for me, didn't do what it was intended to do. As for Ed & Sd, that was a typo... Should have been es & sd... Extreme spread and standard deviation. I do think both matter and especially as distance you're shooting increases. If the extreme spread of our reloaded ammo widens, so will vertical groups.... And sd is just a another way I'd indicating that bullets are consistent or inconsistent with respect to velocity. Sorry for the typo. [/QUOTE]
