I fired the first batch of .223 I made up over the weekend, and they worked great but the cases didn't seem to stretch at all. When I made them up, I needed to trim all of them and did so, getting them to about 1.250" +/- .004". I found that after running them through my AR, they were all ... 1.250" +/- .004". What gives?
Don't get me wrong - I'll be ecstatic if I don't need to trim & debur every time, but I expected at least some case growth.
The load BTW was 24.5gr of WC844 pulldown under a 55gr M193 projectile.
