Results from sorting 600 bullets 0.308 caliber 210 gr. Berger. My understanding is that to shoot at 1K you want to sort them with-in 0.002". From goodgrouper's experience seems like 0.002" at 2K will give a large vertical spread. I have also read that you want to sort them with-in 0.003" from Bearing Surface manufacturers, I could be wrong, but they don't say what distance they're good for. I'm limiting my shooting on paper to 1200 yards . 539 pieces which is 89.83% fall within 0.002" and 412 pieces, 68.67% fall within 0.001". All comments are welcome. Would it be good enough to sort within 0.001 for 1200 yards?
