Awright Guys:<P>It's been 20 years since I read the explanation. I need a short refresher course. We are advised to keep our reduced load brass separate from the rest of our brass. Somebody asked me why? If I remember right, I think it's because the brass may not fully conform to the chamber, and upon subsequent use in full power loads may create a condition akin to excess headspace. I dunno, so I come to the feet of the guru's. Any help ....oaklane
