Mosin question

[ArtyMan]

Hey guys,

Today I was cleaning my Mosin, and after a while I noticed the cleaning patches were coming out blue. Any ideas as to why? Im using standard Hoppes #9 and a soviet 91/30, and was firing czech slivertip.
The barell looks fine (very clean!) im just wondering as to why, it's never done this before.

Thanks

Maybe you're getting some old, hard copper residue out, that's taken a lot of solvent to disolve?

That would indicate you are removing copper fouling. Maybe you never had copper fouling before, something different about the bullets (copper wash), other??

Copper fouling ...

Just look on it as your Mosin barrel has been protected by a layer of copper.

I believe you have one of the few Mosins with the ultra rare copper plated barrel. Similar to chrome plating the barrel for protection against fouling and corrosion, the Russians experimenting with plating the inside of their barrels with copper. Only 10 were ever produced and you just destroyed one of them. Way to go.

wow i never knew that.

What if I add a ? Still believe me? I wouldn't.


To the original poster, it's nothing serious. Just some copper residue, my 91/30 never has patches coming out clean. Ever.

Just make sure you go and clean again in a day or two. The czech ammo is really corrosive.
Leave the bore wet overnight and you will have more blue copper come out.
