[QUOTE="KYpatriot, post: 1027121, member: 48028"] this looks like a good methodical process to me but I'm sure I could nitpick a couple things for you to consider. I think having brass from the same lot, weight sorted, can help with consistency. This may not be noticeable in your final product depending on the inherent precision if the rifle, your skill, and the distance you shoot. I think you should get some good calipers and a comparator to attach to them and actually measure your fired brass, and then your sized brass, so that you know for sure you are only bumping the shoulder .001-.002. You'd have to be pretty good to do this by hand, and you have no way to QC the brass after sizing without getting the rifle out. You risk oversizing, which would be particularly detrimental to the 7 mag brass life. The only thing you can repeatably do by hand down to the thousandths of an inch is feel depressions or ridges with your fingertips- this isn't that kind of " measurement". Some people have had good luck with Hornady one shot, others have got stuck cases from time to time. I have loaded thousands of rounds with imperial size wax and have never had a stuck case, and have never heard of anyone sticking a case with it. Whatever lube you use, after the round is complete I wipe them off with a t shirt wetted with rubbing alcohol so they are clean if all lube. This is so the brass can grip the chamber walls as it is supposed to, greatly reduces bolt thrust. I think the two step cleaning in media is unnecessary. In fact it may be detrimental. I reduced my ES by NOT getting the inside of the case neck squeaky clean. Just before loading with powder I also dip the necks in the imperial neck graphite media. The graphite helped produce a more consistent release. I think bright brass is more " grabby" for lack of a better term. What kind of failures do you get on the 7 mag brass? 6-7 reloads isn't bad in my opinion. I think your process is probably pretty good, but since you already have calipers I would for sure double check your accuracy of the shoulder bump since that is a critical step. [/QUOTE]
