New CA Mesa in 6.5 PRC bore condition

[Dhbwa]

Ran about 10 patches thru the bore with Montana extreme copper killer and never got even near a clean patch. Ran outta time so I’ll start up again tomorrow.

Seemed strange...

Thoughts?

What is under your patch... a bronze or brass jag or brush? That will cause the patch to discolor.

Same brass jag that works flawless in other bores....
