Good morning, I had a similar problem with my M63. Somewhere on this forum someone mentioned Militec 1. I tried it, swabbing the chambers with a drop on a q-tip and heating the cylinder with my wifes hairdryer until I couldn't hold it in my bare hand. I did that 3 times. Of course I had taken the cylinder off the gun when I did this. The next time I went to the range I shot 9 cylinder fulls and the empties popped right out with out a problem. Might give it a try. A bottle only cost $8-9.
