Just because it rains doesn't mean the Gun powder will become wet. Look at all the battles where the was rain during the revolutionary war, and other wars, and soldiers didn't have problems with wet gun powder. The gun powder is in the gun, so unless you dropped the gun in water, it was most likely fine.
