I have some new factory .44 Magnum ammo that I'm guessing is over 20 years old. The brass has got some corrosion on it from improper storage. I'm debating on whether to shoot it, at the range, or not. My concern would be safety and damaging the gun, which is a blued Lew Horton 5" Ruger Redhawk. My other option, I'm thinking, would be to pull the bullets and reload them into new brass at some point.
