The right holes in the die are plugged and I have the punch set correctly. I tapped the bullet down into the die until the lube groove was visible through the holes. Then I lowered the punch to the bullet in the machine. Everything worked great for about 5,000 bullets or so and now it's not filling up the groove all the way.
The Air pressure setting is at 100psi and the heater base is at about the perfect level. Not too runny not to solid. I have no idea what the hell is wrong. Sometimes the first few bullets will be great and then it will start spitting them out with the groove only partially filled.
I know that the air pressure doesn't effect the lube filling the groove. What I'm wondering is how I would increase the pressure that forces lube into the groove? Can anyone give me some ideas on how to get this fixed?
I've tried turning up the heat and it gets too runny.
