I was recently gifted a borescope (I know, one of those things I should never look through). Anyway, stuck it down my R700 with a factory barrel (308 Winchester). Has about 2800 rounds down the tube. You can definitely see some barrel wear. I think everything looks normal though.
To my untrained eye, looks like I've lost some rifling. Is there any way to tell from the pictures how much?
