[QUOTE="orkan, post: 2117237, member: 25377"] I'll list a few things, then my answers to those things. There are unlimited things to list, and unlimited discussions to have about each... but I'll just shortcut to a specific few that tend to spur the most drastic improvement. The reduction of ES/SD is literally what this entire handloading discipline is about. As such, there are no easy answers. Annealing - (bench source or AMP) Neck turning - (Bryan Blakes new AutoDOD) Correct tumbling methods (not stainless) - (vibratory tumbler with rice) Proper FL case sizing - (custom FL sizing dies built from your own resize reamer) Extremely precise Optimum Charge Weight testing - (Prometheus GenII powder measure) Proper component selection - (run a powder that has as slow a burn characteristic as you can get away with, for a soft pressure curve) Extremely precise primer seating depth testing - (Primal Rights Competition Primer Seater) Extremely precise bullet seating depth testing - (custom micrometer bullet seaters) Properly timed ignition in your rifle - (Lone Peak Fuzion action, with minimal to zero cock on close, with no excessive sear, cocking piece, or firing pin drag) Done correctly, your SD should be below 3-5 fps... or inside what your chronograph will be able to resolve reliably. Single digit ES's are achievable if you spend enough money on equipment and enough time learning to use it. [/QUOTE]
