Thread: Cleaning Heavy Copper

Hi all, Ive got myself a new 300wsm that's running 180gr accubonds at 2920. i haven't put a lot of rounds through it yet so still learning its behavior but what i do know is that it is fouling terribbly, as in after a few rounds i can visually see the copper in the barrel. last range day i put 16 rounds through it and after an hour of cleaning i can still see the copper on the lands, and my patches are still visually blue in four strips.

A bit more info for people to answer me with,
Im not a newbie, i have been shooting f class for a long time so i have spent a lot of time cleaning barrels and have never had one of my comp guns come up like this, all my cleaning methods have worked after 10 to 15 min max to give me clean patches.
i use for a quick clean and finish off with bore-tech eliminator and have ally jags for true readings, Ive only ever needed to do push through patches to get the job done.

the questions i really have is what are the current techniques and products recommend for copper? used to be nylon brushes and eliminator. have other accubond shooters noticed the high copper fouling?
i did a basic break in with shoot and clean. i have less than 40 rds through it so far.

Cheers, for any help and keen to get the chat going.
