[QUOTE="jrock, post: 1745155, member: 78569"] I've shot chambers that show rings on the brass and have ejected just fine. I've shot ones that were a bright reamer finish and extracted fine. I think the Hinnat book suggest nothing finer than a quick buff with 320 grit in the chamber to rough it up from the bright reamer finish. Varmint Als website has some good FEA models showing the differences between rough and polished but I'm sure you are all aware of those references. Like I said, on the Remington I sent back, I didn't see anything wrong with the brass or chamber. I might have tried some feeler gauges wedged between the bolt and action cam surfaces with no benefit. That barrel also shoot the same velocity over the chrono even if I went up 3 or 4 grains of powder and maxed out 300 fps slower. Something was really wrong. [/QUOTE]
