Friends, I have never seen anything like the barrel of this Gustaf 8x58RD Rolling Block.
The barrel is a veritable coal mine!
I have made over sixty passes of (insert bore cleaner name here), soak overnight, wire brush, wire brush with brass scouring media, Corbin bore shine, Rem bore cleaner. Name one.
I am careful to clean the bore with brake cleaner and such when I change solvents.
NOTHING. And, friends? I MEAN NOTHING MAKES A DENT IN THIS SUCKER!!!!
I've never seen anything quite like it.
Image below after about the 60th pass; soak overnight or more, scrub, patch, and do it again (kind of like shampoo instructions?)
I've even tried the Lewis Lead remover in hopes that it will scavenge carbon. No joy. None at all.
Thoughts? Ream and reline?
I'll eventually get the bore image in here but this web page is being recalcitrant.
Why does this page only give the the option of loading from a web cache when most times I can upload from my computer??????
I'm not even sure these links will work.
What a PITA.
Suffice it to say that I have NEVER seen this much carbon in a bore before.
