[QUOTE="Clark, post: 575809, member: 6600"] That was wry and succinct. ~ 10 years ago we cut a 243 chamber in this Chrome Moly bull barrel and cut the crown at 11 degrees. After a trip to the range, I left Sweet's 7.62 Copper solvent [Ammonia based] in the bore over night. In the morning, the muzzle had become etched. I gotta get a digital microscopic, you should see how bubbly the etching looks. I am now into KG-12 for Copper. [/QUOTE]
