Why only two re-loadings? Lost brass in the bushes? Or do the cases start to fail? I have only just in the last six months started reloading 223, but my 243 cases have been lasting for quite a few loads, one set of 20 has been reloaded at least five times.
Spleify: Also, if you reload 5.56 brass, the case volumes are a little less than 223, or so I have read. I use two different loads for 223 vs 5.56 cases I have. I should note that on the "223 vs 5.56" thread.
It was just a number. I have .223 brass that I have loaded 5-6 times so far. Go take a look at that thread again.
