[QUOTE="rcoody, post: 1190266, member: 91090"] I have been able to get my es down to 10 and sd of 4 in my ar turbo 40 improved It is an accumulation of a lot of things. I use lapua brass with br4 primers custom dies in a co-ax press clean my brass with an ultrasonic I anneal every 3 firings and I weigh charges to 0.02 grains I believe neck tension and accurate powder charges have had the greatest effect on my SD's [/QUOTE]
