I figured this would be a better place to post this question rather than in the ammo section. But im new to the "Ak" scene and ive been looking at ammo and found a deal on 1200 brass cased rounds for $175 but it said that it was corrosive and im wondering what the negetives are to shooting this ammo? Im planning on getting this for range practice because my range dont allow steel cased ammo. Is there a long term problem with using corrosive ammo and is just being cleaned after i shoot it good enough? But im also planning on getting russian surplus ammo that is sealed in a tin for stock of ammo just to have it on hand for a rainy day that is steel cased. Thanks.
