I recently bought (from Samco) a M1916 Spanish Mauser (converted to 7.62 Nato) and took it out to fire it for the first time today. I fired the first round, tried to eject the round and I couldn't. After several attempts, I ended up taking a cleaning round down the barrel, tapping on it lightly to loosed it up so I could work the bolt enough to remove the spent shell. If figured it might be the ammo (which was Chinese Surplus 7.62). I tried different ammo but that same results. The only way it worked was by using match-grade .308 ammo (which is really expensive). Does any one have any suggestions? I really like the gun but don't like the hassle. Appreciate the input!
