My first pony, 1970A1T, with a PM-9 chaser

[Grouse]

I ran 200 rounds of tula steel cased through it. With 0 issues, I then ran one box of brassed cased remington umc and had a failure to eject. At this point though the gun was smoking hot. As the 200 rounds had been very fast. I will give it a pass, I had no other issues with the brass ammo after a brief cool down. I need to clean it and get some photos for you.
