Being curious about what Lee means when they recommend pushing the handle a minimum of 25lbs, I ran a quick experiment this morning.
Using a Forster CoAx press with a Forster stubby handle, I set a 200kg (440lb) capacity load cell on the shell plate and zeroed it. I let the handle gently down onto the load cell; 28lbs, that's without applying any force to the arm, just gravity at work. Using a Lyman trigger gage attached to ball of the stubby, I pulled to 11lbs 10oz (the gage does not read above 12lbs), the load cell reports over 400lbs of force
So, I'm still not sure what the 25lb suggested force Lee recommends but, I'm pretty sure they are not referring to the ram force on the die .
If Lee means applying 25lbs to the press arm, that needs to qualified according to the mechanical advantage offered by the press itself. If approximately 12lbs of force on the stubby lever of a CoAx can generate a compressive force on the ram in excess of 400lbs, that will be very different with the standard length arm.
Anyway, we all have our techniques for using the Lee collet dies, not trying to change my mind, or anyone else's, just curious is all.
You are starting to worry me. 🙄😂😋
