[QUOTE="Pdvdh, post: 839707, member: 4191"] I think the problem was clearly ID'd as an excessively large diameter chamber - relative to the body/resizing die being used. The problem has been idenitified, and solution(s) provided, for [B]jsthntn247[/B]. I open up a resizing die once using valve grinding compound spinning on a dowel connected to a battery operated drill, but the die ended up being non-concentric. The steel in these resizing dies is surprisingly hardened up during the manufacturing process. It took a lot of dowel turning time the way I went about it. [B]Bullet bumper[/B] has devised and implemented methode to accomplish the job correctly. I knew my method was susceptible to runout, and that's exactly what I ended up with. I still use the resizing die, but it bugs me every now and then that booggered up my die. It was an RCBS sizing die for a .280 RCBS Improved - 30 degree shoulder. Based on that experience, and no experience casting chambers with molten lead, I'd probably lean toward the [B]Mikecr[/B] solution of a custom die for the rifle, if it was a rifle I loaded and shot a lot. 247 just needs to decide how he wants to resolve the problem of limited casing life.
