Hello guys. I have a model 53 that I have tried firing ppu ammo from. When I first got the gun I tried to fire some and the first shot works and it's hit or miss. I pulled the gun all the way apart. Degreased and cleaned all the parts. I oiled the moving parts with rem oil drops. I took the gun out today. I loaded 2 ppu cartridges in the cylinder and first one fired second one not so much. All single action. Is it possible the ppu primers are that hard. I have dies and Remington brass I've been saving to load some ammo. Should I buy some bullets and powder and try that? Thanks
