[QUOTE=".300 Dakota, post: 2326391, member: 106514"] Medical charts are easy to read... with several years of education and training... I doubt using a bore scope would be as difficult. Lol! I have never used one either, but have always wanted one. Basically, and guys who know can chime in, you are looking for anything that deviates from perfectly smooth and concentric. You can see chatter and roughness in the chamber from the travel speed of the lathe being too fast, the cutter being dull, where chips were allowed to pile up in the way, or overheating from lack of coolant, or some combination. In the barrel, you might see scratches or burrs on the lands or the grooves being inconsistent, etc. I just know this from looking at photos on the Internet, of which there are many out there. However, just because you see something, doesn't necessarily mean the barrel won't be accurate. Savage factory barrels have been an anomaly pointed out time and again about looking like crap on the inside, but may outshoot many custom tubes. What a rough-cut barrel WILL assuredly do is foul easily and require more work to clean, and need cleaning more often! (This I've read, too.) [/QUOTE]
