[QUOTE="ChrisInKY, post: 1353829, member: 94377"] Both before and after (if I understand what you're asking). Just before full-sizing or bumping the shoulder back. And again, just before final neck-sizing. The results in ES/SD are telling, but there are deep rabbit holes here. Annealing de-stresses brass. Use your calipers to measure your brass at the range just after firing. Measure again the day after. Measure before annealing and again after the brass is cool enough to handle. Measure again a day later. I'm sure you'll find variations in the .00Xs. If you measure frequently, you'll find those measurements almost go back and forth from what common sense might dictate. The variations I mentioned previously might lead you to reconsider when you want to shoulder bump. Try repeating this process with brass that's quenched immediately after annealing. I believe you will find the case neck does not relax as much and your ES/SDs will trend up. Also, you can get different annealing results with brass that has been washed clean and brass that has carbon/graphite residues remaining. [/QUOTE]
