Yeah, I've had the brown residue left over from boretech. Its brilliant for removing copper fouling. As the makers say, its not rust.
I flush the barrel with meths after now, just to flush all the crap out. Now longer see the residue.

Welcome to Sako club.
I use Autosol very sparingly and then only to remove the carbon ring I get just fwd of the chamber when I use W760 powder. That black mark you get on the patch for ever and ever when cleaning with Autosol is parent metal from your bore. I would generally use JB's first b4 Autosol.
I got some KG12 from Aus many several years ago b4 it was available in NZ. I was not that impressed with it. Sure all the tests say it is better than Boretech but it is shite to use - runs off your patches like mad, plus leaves no visible evidence that it is doing its job. When using it I had to get the borescope out and check all of the time. Then one of the plastic bottles sprung a wee leak at its base and drained itself into the bottom of the gun cupboard. Fark all gone. I reverted to Boretech Eleminator and Cu solvent, and use them along side bore foam. Neutralise any of them before going to a different type using either meths or CRC Brakleen and never store the guns with solvent in them despite what the manufacturers say.

I got same problem same rifle (a Howa heavy barrel in .308) only 2 or 3 spots inside the action , brand new gun, i freak out but i'm calm now removed those spots with my finger , after this experience i dry the bore and the action before storage and i get thru with a patch of WD40 waiting for a bottle of Eezox .
First i tough is a kind of reaction with Hoppe's (my cleaning routine involve brake cleaner followed by Hoppe's and at the end Bore tech Eliminator) but now i got the "official" answer, thank you @Nasty Factory Trigger .
Regards
I use a rod guide so I don't drip it into the action. I'm too clumsy to use the oil port on the guide, just pop an oiled patch on the pointy jag. I only use a pull through in the hills and then just protective oil not powder or copper solvent.
The worst problem with boretech is its watery and patches jam in the barrel. by the way you need special jags and brushes without copper to get the patches to come clean.
I dry patch the boretech out then use a preserving oil and dry patch that out too. The thin film of oil saves the bore rusting and I can shoot straight through it.
Thanks all for your feedback... i chose the Eliminator as the store person raved about it - seems I chose well - as I later discovered - rightly or wrongly - that Ammonia-based solvents can't be used in stainless steel due to etching...??
