Home Forums Hunting & Shooting Hunter's Campfire Is My Russian-Made 7.62x39 Ammo Really Non-Corrosive?

Now I'm wondering if H03 means it was made in 2003. I know I was buying Russian 7.62x39 throughout the 1980s, 1990s, and early 2000s. Not exactly sure now when I bought these. I still have some from the 1980s somewhere, but they are in blue boxes, whereas these are natural cardboard color.
