[QUOTE="Bart B, post: 655976, member: 5302"] That's better than what Sierra's gets with their flat based bullets shot from rail guns' match grade barrels in their indoor test range, as far as I know. What caliber and style were these bullets? Flat based bullets well balanced when spun fast will shoot more accurate than boattailed ones that ain't so perfectly balanced. There may have been a slight difference in bullet diameters between the flat based ones compared to the boattail ones which caused the difference in accuracy for that barrel. Sierra had problems with this some years ago when the jacket material they were getting did not coin, cup, draw and shape to consistant jacket dimensions; they had to change suppliers. [/QUOTE]
