I originally converted the Lapua brass with about a .0025"- .003" head space and had no soot beyond the neck. Out of 35 rounds I think it was 5 or 6 that didn't feel right when I went to resize and is quite possible there was no visible belt until it went through the die. I'm pretty sure I was using CCI 450 primers loaded 5 rounds of each charge with Lever @ 28.1, 28.4, 28.7, 29.0 and AR-Comp 25.0, 25.3, 25.6. I don't know what load swelled the cases because I didn't notice anything out of the ordinary until I went to resize them. Measurement at the base/head on those were .4395-.440" and may not be a problem if using a die other than Hornady.
