RE: humidity effects on powder
Best thing to ever happen in Illinois was the check station!!! We did away with them a few years ago, and I garauntee the amount of deer illegally harvested has sky rocketed!!!! I wish we could in some way get them back!-----------------Not a silly thing at all!
Anyway back to humidity, I don't think humidity should affect your ML hunt whatsoever! The thing you should worry about is your barrel sweating, that's when you bring your gun inside from the cold outside, that's when moisture can penetrate your powder no matter what powder you are using! The only way to prevent it, is to somehow leave you ML outside, so that there is no drastic temp. change. I leave mine locked up in my buddys pole barn. Once I load it and go outside with it, it never comes back in, until the end of the season. Our seasons only run for a maximum of 4 days.
