I've had a star sizer for a couple months now, and it has been quite frustrating. One day it will crank out bullets, and the next it will become the fastest mess. I've tried two lubes, and 3 bullets on it. The first lube I don't know what it is. I assume it is Magma lube, and the next is Canaruba Red. For the most part, the .452" die works ok with the one bullet I've ran through it. Today I was trying the .314" die, same as last time, same bullet, no changes, and it will not fill a lube groove. Neither die is clogged, and I don't think it is die specific as both have done it. The .314" die does seem more temperamental though. I'll post a picture below of the best I could do today. That is with the pressure turned all the way to 95 PSI, and heat is higher than I like. With the temp that high I get some lube in the crimp groove, and nose, as well as some often falls out when the bullet drops. With the temp set the same place it was Monday, I get half the groove filled. I've tried adjusting the punch up and down with no change. For all the time I've put into trying to troubleshoot this thing, I could have just slowly been sizing on the old Lyman 450 the whole time.
I only have one idea, and that is air. I've tried the bleeder screw, and I've tried running lube out the die without a bullet. I sometimes get pops like there is air in the lube. I have been using a hollow stick of lube, is that causing the air I am getting, or is there another problem? I am fully stroking the handle, and have tried holding it at the bottom to let the lube go longer.
