I just got a new bag of a 100 Rem .223 brass to do some lader test with. Last night I started measuring all the cases and was surprised with the OAL to be with in .003 of each other. With 90 of them being exactly the same, and only 2 were .002 under, and 2 cases were unuseable. That left 6 that were .001 biger then the average. I will be loading 69 grain SMK's with CCI primers and H335, Varget, BLC2, and RE7. Tonite Im throwing powder and hopefully the wind will calm down and I can do some testing.
