Hi just wondering if any body crimps 223 rounds ,why I ask is because went to the SSAA range got set up opened a box of reloads, I had 1 round that was pushed back into the case, now didn't use that box ,when I got home use my RCBS bullet puller to check neck tension ,bit crude all felt tight ,so collected the bullets ,powder and reassembled them , ok where did I go wrong it never happen before.........
