The Swiss never used corrosive ammo in these. All bets are off in an old used rifle though.<G>

Spent ten minutes cleanng the barrel, it doesn't go away.

Just wondering if they ever used corrosive ammo or this rifle was just not well taken care of.

The "Green" more than likely is Swiss rifle grease. I think that it is called Automattenfett, or something similar. That stuff is everywhere, and it likes to gather in the chamber. Just clean the barrel when you are done shooting and you'll be fine. I have yet to see a bad barrel on a K31.

This is probably what you see....

It is normal. This is what my 1934 K31 looked like when I cleaned it last.

The GP11 isn't corrosive? weird.

It's my understanding that it's all match grade ammo too.... I guess that's what you make for a country full of target shooters.
