[QUOTE="Bart B, post: 498169, member: 5302"] Just who are the best LR shooters? I ask because there's 3 or 4 disciplines who have excellent LR shooters. And there's not a bid of difference in their hardware's accuracy. Meanwhile, back to meplatting and trimming, I don't think the Juenke tool would be as good as one that spun them upwards of 100,000 rpm or higher. The Juenke tool did a good job of measuring jacket and case wall thickness, but not the mass of core plus jacket spinning about its center of form. This is what the bullet does going down the barrel. Any offset between center of form and center of mass is what causes the bullet to exit the muzzle at an angle to the bore axis. Surely there's a motor that would spin 'em that fast....somewhere. Even an air dirven one would work. Such as those used to spin rate gryos at ultra high speed. [/QUOTE]
