Question about Forster Coax Press die setup

[p5200]

I'm not quite clear on how tight to tighten the screw that bears down against the dies silver lock ring? The directions say just enough to keep tension on the lock ring. Should I be able to twist the die and lock ring assembly back and forth in it's slot or not? Thanks!

The tension screw in question, is #28 in the manual.

It does not have to hold the die still, IMHO it is there to keep the die from working out/falling out. This screw does not determine the setback on your brass - you will notice that when the lever is fully depressed and the ram is fully up is the ring is indexing off the top of the slot for the die/ring, not the screw itself.

It only needs to be tensioned enough to stop the die from coming out too easily. I can rotate my dies in the 'slot' with the amount of tension I use.

Having a bit of 'float' in the die and shellholder is a good thing - it helps the case center properly as it goes into the die and can reduce runout. It's rarely the case that anything other than precision machined parts will meet and align perfectly if 'locked' into place

That set screw has a spring loaded ball in its tip. You don't want to tighten it so much that the body of the set screw protrudes above the bottom face of the slot, just the spring loaded ball should protrude. Otherwise, when you go to retract the cartridge from the die, a screw advanced too far would keep the die's lock ring from resting squarely on the bottom of the slot.

When properly adjusted, mine actually protrudes in front of the lock ring, which just keeps the lock ring and die from backing out of the slot. The body will contact the lock ring if it protrudes.
