[QUOTE="freddiej, post: 1710722, member: 26227"] Since I competed in 1,000 yard comps I see some things that I need to add to this discussion.. first, I reamed all the necks of your brass to be uniform and concentric. even Lapua brass has 0.001" to 0.004" variation from side to side and from one piece of brass to another. I used to do both, and found only that the brass wears out faster with full length sizing if you did not anneal the cases. next most all seating dies these days use the primary bore diameter to seat the slugs so they are never consistent COAL they are all ogive or lead uniform. next I use a wet/steel media polishing method and it cleans both inside and out, even the primer pockets get clean. I also keep my necks at maximum length just because I choose to. other than that. I used some of the things I saw up there for prep but not many. I was the odd man on the 1,000 yard team. [/QUOTE]
