[QUOTE="406pat, post: 647102, member: 13575"] I would say signs are pointing to the chamber being out of round. My only hesitation would be the aforementioned Hornady brass woes. I know of a guy (on this site actually) that manufactures a semi-auto .338 Lapua and they had issues with Hornady factory loads. If memory serves, they were getting case head separation. For my money that means the brass has the potential to be the issue so trying proven brass and casting the chamber would still be my recommendation before you make a move. The micrometer got me thinking, if you have or know someone that has an inside mic that's small enough, that would be a good test and may tell you what you need to know. If you set the mic to depth just inside the chamber it should keep constant contact when you rotate it. It would be tough to keep the mic in line with the bore without some sort of fixture and any wobble may give a false reading, so I'd still want to do some more investigation before I declared the chamber messed up, but it might help narrow the variables down. Just a thought. [/QUOTE]
