RE: Wet powder, no buck!!
Big Boar.. that is a terrible sound and feeling. I do not remember the kind of rifle you were shooting. Perhaps you could tell us about your rifle, powder, and how you water resistant/proofed the rifle for your wet hunting conditions...
Not only would it be interesting but other might learn from your misfortune. Especially if this was one of the new powders on the market, or perhaps you were hunting with it for the third or fourth day in a row. Then your storage might be an issue.
Again, perhaps you will get another chance.
