Condensation fouling vs fouling fouling

[armymedic.2]

Great info and links popping up on this thread. I thank you all for the education

Since it was mentioned the powder will dry on its own i must ask, is any burning potential lost or changed by being wetted then dried?

Just got back here...Thank you, necchi, for this link. I am up to page 10, and this is a great source of information.

And thank you, colorado clyde for pushing us to question what we think we "know".

Folks like you two are what makes this such an excellent forum for learning. :hatsoff: :hatsoff:

If you read the Mad Monks stuff you'll find the moisture content of BP around .5% and his tests allowing BP to gather RH moisture it increased to 1.6% then he dried it back to 0.0%. That was just his experiment to show BP being hygroscopic. Off the top of my head I'm not sure he shot those test samples.

I was once given about 1/3 of a can of Goex 3F that had been in a garage here in Minn for about 30yrs. It was clumped so badly some of the chunks would not "pour" out of the can. I got it all out, broke up all the clumps with a rolling pin, put it back and used it.
That powder just wasn't right, it didn't have the same power as new 3F, it all went off without a hitch but it didn't "Bang!" like a normal load.
I guess I could have messed with the load and got what was normal for that PRB combo but there wasn't enough to mess with, so I just shot it all up on the range and called it practice.

I suspect the moisture content was still to high, affecting it's performance?

It was pretty dry when I worked it,, I think it had just cycled Hot/Cold-wet/dry for many-many years. I guess it was stuff left from their "grandpa" who had passed years before.
The stuff could have been from some of the "bad run's" Goex had years back
