[QUOTE="Sludge, post: 30325, member: 1928"] Im interested in long range hunting, however I may try my hand at a 1000yd match since we have a 1000yd range about 20 minutes away from where I live. I think it would be a good place to do some learning. I havent done much chrono work yet, just a few 5 or 10 round groups with different bullets and powders. My ES has been higher than I wanted to see it. However, in some cases I cant for the life of me figure out why it is so high. For a 5 round group I have had some 29s etc. Sometimes I get a lower one. Then, once in a while I get a 90fps spread on some ammo that I know was loaded very carefully. Primers? Bad lot of powder? I have weighed the bullets and brass into uniform groups. Neck and length turned the cases. I throw my charges with a RCBS electronic scale and dispencer then I do the final .1 grain or so by hand on a beam scale. I have been VERY careful with the powder measurements to make them as uniform as I can. I wish I had two chronographs to set up to compare measurements. The chrono im using is a Pact Championship Timer/Chrono. Any suggestions? [/QUOTE]
