I am a Wipeout lover and check my bores with a Lyman borescope which I really like for about $200.
It's been my experience that Wipeout sometimes stays ahead of carbon fouling and sometimes it doesn't..... but it almost always does a stellar job on copper. The other funny thing you will learn with a borescope is that sometimes even the roughest looking barrels don't always collect a bunch of copper. Some tight fitting patches with kroil oil and a little bit of flitz metal polish seem to doll things up pretty nicely for me when things start looking ugly...... but I understand there are some newer carbon Cutters that are pretty wonderful too. I have never seen somebody who bought a Lyman borescope regret it for the money!
