My PC is pretty old and decrepit and my tablet won't take SD chips so you'll have to see this..lol.
Here is a picture of a land in my moderately used Tikka 3006. Wipeout is getting all of the copper fouling out but there's a little bit of carbon here and there. My gunsmith says Sierra has a product that will get that stuff out but it probably isn't needed .....my bore looks pretty good.
