[QUOTE="6fatrat, post: 1332067, member: 76336"] For my 1000yd prone rifles I use brass [Lapua] from the same lot, weight sort, neck turn, anneal then fireform. I anneal after each firing. I use a bushing die sizing my necks for .001 to .002 tension, I also moly all my long range bullets. Get a good electronic scale and use the Hodgon extreme powders. Test different lots and manufacture of primers. Extreme spreads should be under 10. I would start at .010 jump then move into the rifling from there. Steve Bair [/QUOTE]
