So I loaded up a bunch of .223. Did a full length resize with small base dies, trimmed the cases to 1.750", added powder, primers, bullets, all the usual stuff. I went out and shot a bunch of it a couple weeks ago and just discovered that the fired brass now measures 1.740"-1.745". This was fired from a DPMS 16" pencil barrel with no FTF or FTE issues, everything ran flawlessly. I thought the brass would stretch a little when fired???
