Highroad Team, I have encountered an interesting problem. A colleague of mine gifted me a large box of .223 and 5.56 brass. I de-primed, wet tumbled, and removed the primer crimp. I set up the T7 with a Redding FL .223 die. I calibrated a Redding Instant Indicator set up right next to the FL die, so I could take immediate measurements. I selected a few cases to set the FL die to size at .001-.002 above SAAMI minimum. I locked the die in, and I got ready to FL size few hundred. Prior to sizing I measured the cases with the Instant Indicator and found them all to be .007 above SAAMI minimum, so I knew that was the length of the chamber on his AR. So good, so far. This is where it gets weird. I could not get consistent results. After FL sizing each piece of brass, I would run the brass into the Instant Indicator to get a measurement—real time QC. I stopped after about a dozen cases, because my brass was measuring .001-.005 over SAAMI minimum. I have an excellent die that is mated securely to an excellent press. What is going on here? Why am I observing this much variance? Thanks for your help!
