44-40 Magnum Primer?

[Fairshake]

All kinds of different paper is used. I have heard newspaper, cigarette paper, tracing paper such as vellum that is used by draftsmen.

John, when Swiss powder leaves the Corning process, the moisture content is 8% ... onto the Polishing process.
When the powder leaves the Polishing process, the moisture content is 2 - 3% ... onto the Drying process (40C for 24 hours).  When it leaves the Dryers, the moisture of the finished sporting grade powder in the cans is 0.5%

John Boy,
Thank you for that info. I'm thinking the .02% (?) moisture content was referenced as being the amount left in the powder residue after being fired(?).
