I want to stock up on AK ammo for the summer. I have my first Ak, an O-PAP. It seems everyone shoots steel case ammo as it is cheap and Aks seem to eat anything. Then I will hear someone say "I wouldnt use that crap in my gun". For an AK, what could happen if you use cheaper steel case ammo? What else is there besides steel case available for AKs that isnt expensive? Is there any AK ammo that everyone should avoid? Thanks for any replies!
