[QUOTE="dnb86, post: 2909689, member: 124384"] one mistake I made when I was green (not saying anyone in here is ) was bumping shoulders after the first firing and my measurements were off do to the fact that brass needs at least 3-4 firings before bumping shoulders ( in my opinion ) do to that fact that the brass is still stretching on it's own just from the firing. So my next lot of brass I fired off one round measured it and loaded that same brass 3 more times only neck Sizing and that brass grew 6 thousands more before it stopped growing. So if I were to measure the shoulders after the first firing and bumped 2 thou back I was bumping about 8-10 thousands off its true maximum growth and that was just in my chamber so some chambers will let brass grow longer than others as well [/QUOTE]
