Mine is a 6.5-06, barrel is a Douglas Premium 1:10 fitted up by old Din Collings in 1996 according to the stamp. It looks new (there is still bluing in the grooves at the muzzle).
I'd fired 40-50 rounds, didn't check where the fouling was, I just cleaned it out with Sweets. What really surprised me was I then fired a further 15 rounds and cleaned again, and a whole lot more copper (and other crap ??) came out. I would have expected very little fouling from just 15 rounds.
There was no copper on the blemish when I found it (it was after the second very thorough clean) and it was only visible in stong light, but I could "feel" it with a pulled bristle from a wire brush.
