[QUOTE="CMP70306, post: 2412864, member: 36999"] Good Evening Everyone, I recently got a bore scope and a new 6.5 PRC barrel, since I toasted my first PRC barrel in 1100 rounds I decided to take some before pictures so I could compare the wear later down the road. However when I went to take the pictures something seemed off with the lands and grooves. [ATTACH type="full" alt="7FCDE27F-293D-4642-AB3B-B8401AA92BC6.jpeg"]332843[/ATTACH][ATTACH type="full" alt="96D49720-81D7-4CE2-9010-43DAC4CD1AD6.jpeg"]332839[/ATTACH] It looked like there was a gap in the cut between the groove and the land on one side while on the other both cuts looked symmetrical so I backed out to take a picture of the whole lead area. [ATTACH type="full" alt="88828B9D-DB0B-4C68-9790-8E4298E856BC.jpeg"]332840[/ATTACH][ATTACH type="full" alt="58F26ACA-A465-4F5C-8C3C-03FAE6FD1AEB.jpeg"]332841[/ATTACH] Now this is the first new barrel I've bore scoped but something doesn't look right with this chamber. I would have expected it to be more uniform and I'm confused as to how the reamer can cut part of the grooves but leave a uncut area between there and the lands. Any ideas as to what is going on here? [/QUOTE]
