I bought a used Star lube sizer. I do like it quite a little bit. I notice that I am having trouble getting enough grease in the fat grease groove of the Lyman 359 Cowboy RNFP moulded boolit. If I snug the reservoir plunger piston on down, I will get lube on the noses of the bullets, and still have erratic grease groove fill.
Any ideas? I've heard that double pumping the high pressure piston might help, but haven't tried it yet. As it is, I'll do 4 or 5 boolits, and then turn the reservoir plunger in maybe ¼ turn, until it feels snug, but I still get grease on the bullet noses if I do this.
Thanks in advance.
ETA I found the issue. Old dried up lube was forced out into the machined in ring around the die and had plugged one of the holes. Cleaned it up, and now it is working fine. Except now my problem is grease on bullet noses. I suspect that has something to do with the depth the push rod presses the bullets into the die, and perhaps a little bit too much pressure on the lube reservoir.
I'll experiment with it a bit once I've cast up some more boolits.
This is a neat tool.
