I recently purchase a Blaser barrel in 375H&H from Euro Optic. I had planned on giving it a quick clean and head to the range, but after 30 patches of hoppes #9 I gave up. This is my third Blaser barrel, the first two being 6.5x55 and 300 Wby, only a few swipes of solvent was required to get clean patches. Am I missing something or was this a used barrel? They offered me $200 off but if this barrel was used I don’t know if that’s worth it. I haven’t seen a barrel this dirty since my first mosin.
