Most Tula 7.62 ammo are Bi-metal and attracts to magnets
All most all the Mil-Surp ammo like the 7.62x54r spam cans are steel core
the 5.56 Green Tips are steel core.
I have thousands of rounds of Military surplus ammo from 8mm, 7.62, 30-06 and 5.56
So I decided to grind the bullets down to see whats up.
All the Ammo attracts to magnets.

From Left to Right
Walmart Tula 7.62x39 - Lead Core and Bi-Metal Jacket (Range Safe)
1975 Turkish MilSurp 8mm - Lead Core and Bi-Metal Jacket (Range Safe)
1978 Russian Spam Can - Steel Core and Bi-Metal Jacket (NOT Range Safe)
1975 Greek HXP MilSurp 30-06 - Lead Core and Bi-Metal Jacket (Range Safe)
1988 5.56 Green Tip - Steel Core and Bi-Metal Jacket (NOT Range Safe)
But since most ranges will check the Ammo with a magnet they will not allow any of the ammo
above.
so what does one do?
