A Friend gave me some Surplus 7.62x54R Ammo to Shot. I usually use Wolf or Brown Bear Which works in my Chinese Type-53 Carbine flawlessly. However this Stuff was a real Pain as soon as the Carbine got Hot, they started Sticking in the Chamber, and I had to use my Rawhide Mallet to open the Bolt. They have a Dark Green Heavy Laquired Case, which is most likely the Problem, and have a Silver Tipe on the Bullet Stamped 66 at the Top and uxq at the Bottom. anyone know who made it?
