So I shot my first batch of corrosive ammo about a week ago out of my K98 and cleaned with hot water and bore cleaner when I got home. I came back today to check how the bore looked and ran a patch down it. It had very small traces of rust on the edges of the patch. I ran more bore cleaner down it and re oiled and am wondering if there is anything else I need to do. I’m paranoid about ruining the gun now.
