Hey guys was wondering about Lake City LR .308 brass. Its pull down never fired and primed stuff. Are the primers in these good to go/good to use or do they need to be deprimed and re primed? I was told to use a 30ish cal bore brush in a drill to clean the tar out. Thus keeping solvents off the primer. From what I have read they are either military #43 primers or Federal GMM primers depending on when they were produced. Cant find anything telling me exactly what year they changed. Any help is appreciated.
