Free: Contests & Raffles.
Some factory stuff is sealed, I think Federal's Fusion ammo and some of the Winchester premium ammo. I'll look when i get home.My shooting ammo is not sealed...the hunting stuff is sealed neck and primer. Many many moons ago I had a round go Pfffth instead of BOOM. Things were a bit wet inside when i got the rifle open and things picked out of it. Clumps of powder that didnt burn. I pulled the rest of the rounds that were in my belt carrier and my rifle and replaced with ones i could HEAR the powder shake in. Over half of the ones in the carrier and rifle were wet inside. This was after hunting deer and elk out of Forks in 3 weeks of straight downpour.
