[QUOTE="25WSM, post: 2001067, member: 38048"] I see this all the time with customs I make. If you have a perfect chamber length alot of off the shelf dies just can't quite get the shoulder bumped. I put them in the lathe and turn about . 010 off the bottom. It's the easiest way. You can also take some off the top of your shell holder. The reason your brass got longer on the headspace is simple. As you get close to bumping the shoulder the body is being sized inward up near the shoulder and it just has to go somewhere so the shoulder moves forward a bit. When you start seeing your headspace increase you are getting close to bumping. Seems to happen when your within . 005 from the bump. Your chamber diameter may be on the bigger size and causing the increased effort with pulling the handle. Won't hurt anything at all. I personally like my brass sized a little bit extra so it's slightly looser. Years ago the chief ballistics guy at Sierra proved that looser brass in the chamber was more accurate than fitted or neck sized brass. And we're only talking a few thou here. Shep [/QUOTE]
