[QUOTE="Pdvdh, post: 1190299, member: 4191"] Yes, I remember that you prefer to weigh powder charges down to 0.02 gr. I've read your posts on other Threads about weighing powder charges. I'm not critical of that practice. Look at all the time I've spent on 3,500 casings. It's a hobby. I'm glad you shared your approach, and perhaps weighing powder to +/- 0.02 grain would be the additional effort that would drop my ES from 45 down to less than 10. Still not going to do that. I can live with ES 45 in this AR15. It's a plinker. Here's my perspective. I don't weight powder charges down to less than +/- 0.1 grain for any of my other rifle cartridges, and I rarely experience ES exceeding 100 fps as I have in my AR15, even with the worst load combination tested. And I don't have great difficulty getting ES down to less than 45 fps with a reasonable amount of load development effort. I've got more time, components, and rounds fired into this effort to reduce ES/SD with my AR15 than I typically expend on any bolt action rifle, and I'm still at ES=45 over 10 rounds fired. The only reason I've put this much time and effort into it was because I was curious. Anyhow, ES = 45 took me a lot of effort, but it's good enough for my intended use of this rifle. [/QUOTE]
