Occasionally I will get a Lake City 5.56 case, after full length sizing & trimming, where the head will not go all the way into the gauge. Left pic shows it sticking up and right pic shows "normal".
All of the brass has been trimmed to 1.749 - 1.750. Is it a minor shoulder problem with not quite enough setback ? Why is it only 1 in 20 or 25 come out this way ?
I did take about 20 of the ones that stick out, loaded them and shot them out of my AR with no problems. Any help would be appreciated.
