Thread: 303 loads

My suggestion is to stick with moderate loads and discard the brass after three reloads. Haven't loaded any for a few years but I notched the rim with a triangular file before each reload so I could keep count.

While yes run low to moderate loads I dont agree on the early discard of the brass. I have used some brass for over a seasons target shooting so they are on 12+ reloads with no failures in some brass, eg Privy, and S&B and Winchester. 1943 brass isnt so good but then it is 70 odd years old. The brass will show a white line along the bottom 10mm or so circumference as it starts to fail, at that point yes I'd consider scrapping the batch I was using.
