Thread: Keyholing and stiff bolt lift

If you have any of the Greek ammo left I would pull the projectiles, dump the powder, ad reload with a mild AR2206H load. If they shoot well it was degraded powder. If the cases are hard to extract you probably have a mildly corrosion in the chamber - don't panic a gunsmith could polish that out OK. If they still keyhole its the projectiles or the barrel.

My bet is the powder has degraded. I have a friend who's WWII 303 ammo was going off like a 300 Win Mag. We pulled the bullets, and when lit outside it virtually exploded. Cordite definitely degrades over time and moves closer to detonation than a controlled burn, who knows what propellant is in the Greek 7.62 military ammo. There's a reason why armies surplus their old ammo......
