It's possible that the follower in the die is missing or it is an undersized stem mistakenly installed in the sizer die.
Don't crank the reservoir plunger down too hard, just enough to get the lube to flow into the bullet grooves when the bullet gets down into the die. The die stem follower should prevent the lube from flowing between bullets as it is up in front of the lube holes when a bullet is ejected and the ram handle is raised.
It's not in front of me so I'm surmising here.
If it is an older Lyman (45), it should be pretty good quality. The RCBS and the Lyman are essentially the same machine and the dies and top punches are interchangable.
