http://www.thehighroad.org/showthread.php?t=743312 The powder WW 231 5.4 gr. Is what it was suppose to be.The reloads were all brand new Starline so I am pretty sure the cartridges should weigh very close to each other. The weights were fine. And then I noticed one of the primers is brass, others silver. I had loaded 270s a few days before. Would a large rifle prime cause my catastrophic failure?
