hmmm. I had some Federal .30-06 brass which I thought was 2-3x fired, but after firing some of the last batch of reloads, I had case splitting down near the base. I pulled the bullets and ditched the brass. I had not had any .30-06 brass 'fail' after so few firings. They are 'stiff' loadings but not 'hot'. The nickel plated Remington brass is at 6 or 7 firings now and ok so far...
