That brush wont shift it from the barrel--looks like a chamber brush...
I had that problem with a new Tikka barrel...
I shot & cleaned each shot for 5 or 6 rounds, then cleaned each 3 shots for 3-5 groups, then 5 shot groups until around the 30 or 40 round count.
The barrel started to pick up some decent copper at around the 10-15 round mark, & i couldnt shift the copper...
I got fed up with the soaking bore & cleaning because it wasnt shifting the copper (im talking 45 mins of cleaning ) & so went on to shoot another 3 shot group & cleaned immediately with heat in the barrel...that shifted a good bit of the copper, so i gave it another 5 rounds & a clean & scrub while hot & that was it...by 25 rounds it was well & truely gone & i havnt seen copper since.
Im not suggesting the heat in the barrel got rid of the copper, but im sure it helped.
So maybe try shifting the copper with some heat in the barrel...have the cleaning gear ready next to the rifle, send 5 shots down it, then immediately patch out carbon & soak & scrub while warm...patch out, then soak scrub & patch out again...
Then repeat with another 5 rnds...
Just a thought, but worth a try i rekon...

Did you load them to that length on purpose...?...i mean you said you chambered them...
Do you have the gear to, or have you measured the lands...?...and are you measuring the overall length of loaded rounds (to tip of bullet) or to the ogive...?...

Because I’ve been a bit foggy from concussion - I wanted to keep this lot very simple - as I was initially taught. I loaded long on purpose, test chambered and kept bumping the die 1/4 a turn until the bolt would close without effort - turns out that length was over 5mm longer than Sammi max length - but the rounds did fit in the magazine by 1mm. I’ve since checked a couple other reloads and the light neck tension and rough travel might have moved a couple...as the 300wm cases I’m using is pretty tight.
This round was obviously just touching the lands and the slight twist on retraction pulled the projectile. There was almost no force required to bump it out with a rod and id think it would have fired just fine...live and learn.
Guess I know max length now lol
