[QUOTE="Winchester 69, post: 218394, member: 8037"] The inside chamfer of the cases influences the alignment during seating of the bullet with the case mouth. This alignment in turn influences the straightness of the finished load. Since you apparently no longer have any of the earlier batch of bullets, we can't compare diameters. What I am suggesting is that a larger diameter would influence alignment. Examine the inside chamfer of your brass. The most desirable configuration is for minimal outside deburr, and a long, low-angle inside chamfer. Experiment with allowing for more inside chamfer. If you're not using a low-angle tool, usually identified as "VLD", it may be worth pursuing if another cause for the excessive run-out isn't identified. The tools will have a 20 to 30 degree angle. .
