[QUOTE="Bart B, post: 92930, member: 5302"] BountyHunter....If a chrono is important, then why did half a dozen of folks with some of the most accurate rifles on this planet shooting the same bullet, case and primer get the most uniform muzzle velocity and worst accuracy with AA2520 ball powder? (see my earlier post). And why did IMR4895 powder producing just average muzzle velocity spreads produce the best accuracy? A couple hundred people shot that ammo in all kinds of barrels with different bore, groove and chamber dimensions; it was the best they'd ever shot. [/QUOTE]
