Hey Poodle,
I'm not sure if we are talking about the same thing, but I got a big supply of Russian 30 caliber bullets about two years ago from Weidener's. They are 123 grain, full metal jacket, spitzer nose, and a flat lead exposed base. The jackets sure look like copper, but they are attracted to a magnet. They are intended for the 7.62X39 ammunition and work real well in my SKS and AK-47 rifles. I have a Ruger Mini-30 and a Colt AR-15 in 7.62X39, but I use regular .308 bullets in them.
Best wishes,
Dave Wile
