Bmg17A1 knows his chows for sure. I knew the privi didnt work but the old ww2 stuf bbn i have works well. Thought it was a lack of pressure thing, thanks for your imput.
Hmm, interesting!!! The gun and AL radiator is marked "N". However the gun was in Finnish service and I noticed that the "N" mark on the receiver almost looks like its had 3 lines marked through it like it been marked out. That would make some sense, I will have to research more on that.The neck swelling may be the difference between Balle D ammo and Balle N ammo. Is your barrel marked with an N? Mine is not and Balle D ammo from WWII will not chamber.
