i've found a lot of 7mm and 300 wm brass and some of them seem to have been resized into 338wm. the resized 7mm brass looks allmost black. I wasn't left with any notes on this process, but i may have over looked some scatterd paperwork.
would annealing be necessary? how much would case life be compromised? lubing of the neck ball necessary? fireforming necessary? ???
