    copper fouling and sbn treatment

    anyone have experience here ?
    i am on my third sbn bbl, my second 10 twist lilja.
    my current 308 win(95 palma reamer) has shown
    zero copper in over 50 rounds in three outings.
    today was close to 35 rounds of lapua 185 fmj/bt.
    entirely new to me, anyone else ??

    I have a Cut barrel

    on my latest rifle and it hasn't attracted any copper at all, in about 600 rounds without any treatment at all. It will shoot all day without cleaning as well (6BR). I decided to go with the Tony Boyer "Break In " regime, shoot it with a knownn load and if it's accurate, Keep shooting it .
