[QUOTE="varmintH8R, post: 921063, member: 39801"] +1. I had an LRH member send me a once fired 338LM case to drill and tap for use on my Hornady OAL gauge. My OCD wouldn't let me sacrifice a shiny new piece of Lapua brass.... The case had expanded in his chamber (just forward of the case head) and no amount of sizing with a Redding body die was going to make it chamber smoothly. I could measure it with a micrometer and clearly tell the difference. I jammed it to fire it, but that didn't allow it to be sized to fit in the future (if you think about it, you really wouldn't expect it to). Had my neighbor turn the bottom of the case down a few thou on a lathe, and it now slides right in. I certainly wouldn't recommend that solution for cases you intend to fire :D Never an issue with new brass that has only been fired in my rifle. I'm on 6 loads and regular sizing leads to an easy fit. As MontanaRifleman said, mixing brass between rifles is bad juju. Brandon [/QUOTE]
