[QUOTE="tailbon3, post: 1133176, member: 19810"] So, I bought a 500 pack of once-fired 5.56 once fired military brass thinking I could easily resize it to 223 Rem. So far around 1/3 of the cases won't resize back to 223 dimensions. I am using a Lyman full-length sizing die and a Lee Breech-lock single stage press. I use this press to resize 300 wsm cases and 308 cases just fine. But the dang 5.56 cases are much tougher to resize. As I said, about 1/3 of them just won't size down to 223 dimensions. I press on the handle until I worry my press is going to rip off my bench or maybe bend the handle. I have tried running the unsizeable cases into the resizing die twice to see if that helps but it doesn't. They are about .002 or maybe .003 too long, measured in a Lyman headspace gauge. I can close the bolt but it's sticky. My thoughts are: Maybe my Lyman resizing die is too aggressive on body taper.?. Maybe mil brass is just unreliable like this? Anyone else had an issue with either mil-surp brass or lyman sizing dies? Should I recycle the whole lot of brass? Or keep the cases that do resize? [/QUOTE]
