I recently got a Dillon RL 1050 press and used it for making lots of 9mm ammo without any problems. Today, I installed a new toolhead and started to set it up for .357 magnum. During the caliber change, I cleaned everything and greased all the components that the manual recommended. I also cleaned out the primer dust from the primer system.
So far, I installed only the .357 sizing die and the swaging station backer / mouth expander die. I lowered the swaging rod all the way down as I don't need to swage .357 cases. I can cycle the press without any problem as long as there is no brass in either the sizing or swage stations. The problem becomes apparent when I run a piece of brass through either of the first two dies.
When I tested the sizing die with a piece of brass, I heard two loud snapping or "boing!" sounds in quick succession when I returned the handle to the upright position. The same pair of sounds are heard if the brass is only in the swaging station. It sounds like a spring is trying to return a metallic component to its neutral position, but something is briefly preventing this component from returning during the upstroke.
I suspect the sounds are coming from the primer punch as it retracts and then immediately after that from the rocker arm, but I'm not sure.
This happens only if there is brass in one of the first two die stations. If no brass is in the shell plate, no strange sounds are heard.
Any ideas what is going on with this machine?
