i lived in central fl for 15 years, and reloaded in the attached garage. never saw any rust on anything.
I spent a lot of hot sweaty night loading ammo.
left powder, primers, and loaded ammo in there year round
must been them "cool ocean brees"????
or magic?
luck?
I lived on east coast cen. FL 2 yrs
never loaded a single round.
all my gear was stored in Indy
