I have read that the Herters ammo for 7.62x39 is just repackaged russian ammo (wolf, tulammo, et. al.). That referred to the steel case ammo - I thought. I am on the lookout for inexpensive expanding self-defense ammo to buy in bulk for 7.62x39, 5.56x45 and 7.62x51 I was in Cabelas today and noticed they had some Herters brass soft point ammo for 7.62x39, the brass case has a headstamp of "herters" so I bought a single 20 rd box, thinking this might be an exception. I get home and I am doing some research on this ammo, and I see a vid where a guy is testing 154 gr. SP projectiles that come in the steel case Herters ammo (I could see the Tulammo headstamp on it) and he found that the jacket on the projectile was thick steel, probably copper plated. So I found a magnet, and sure enough, this stuff is steel jacket. I should have known better.
