Muley, you seem have have difficulty understanding what you read; first on the Colorado elk regulations, and now here.

What i wrote was, ' Several times i have reloaded a dirty rifle, and continued the hunt for days and/or weeks. Most times this worked just fine. However, ever once in a great while, the rifle would of a sudden, rust.'

I agree with Carlos that Blackhorn powder is very good about not rusting rifle barrels. One can go years of hunts, and see no rust. However, when least expected, rust can/may happen. It happened to me and to others. People should 'know' about this, so they can treat their rifles accordingly.

Myself, i 'proved' over and again that Blackhorn powder will never rust a barrel. It was 'proven' to me so very many times, i took it as a 'known'. One test doesn't prove an idea correct. A jillion tests don't prove an idea correct.

One example of Blackhorn debris rusting a barrel, does prove it can and will rust a barrel.
