I find the most consistant brass to be civilian, non crimped, such as R-P, Win, S&B and best of all, Hornady. No Federal, even the current stuff. I have a batch of once fired LC07 that is very poor for reloading due to large primer pockets. If brass quality is in question, look for sealant on the primer, heat discoloration from anealing and so on to determine if it is once fired. If the primer goes in with little or no resistance, press it back out and toss the brass. Make sure brass is trimmed to length. Load small lots to get experience so that if a mistake is made, it won't be a costly mistake. you won't save much reloading 55 grainers but you can load "match" rounds and save quite a bit. Try Sierra 69 hpbtm with their accuracy load, 25.3 Varget I think but don't trust my word, look it up. Good luck, dlblem
