Where can I find cheap, non-magnetic 7.62x39 ammunition? - where can i get cheap metal core wheels

My local area has a stick up your ass and do not let me shoot balls, which attracts a magnet. (Fear of a bullet hitting a rock and a fire). This includes the steel core, steel or bi-metal jacket bullets. .

I look forward to at least one drawer 1000 Round 7.62x39 buy for my SKS. Ive been to look cheaper than the Wolf ammo, but a "Bi" Metal Jacket.

So if you do not know from CHEAP-magnetic ammo out there? Thank you in advance for any help.

ALSO ---- do not worry about the case. Steel can be coated does nothing.
