"Bedding" Dillon 650 toolheads?

[David2011]

Here's a tip from the Dillon manual. I may not have it verbatim but it's close enough. With your dies adjusted, loosen the locking nuts on the dies and cases run through them until you have all positions filled. With the stage in the raised position snug all of the lock nuts. That lets the dies float to their best centered position within the tolerances of the threads of the toolhead and dies. This can really help if you've been catching the mouths of cases on the sizing die and helps bullet runout as well..

When the little one gets older babysit with a mountian dew and snickers bar. He will run at full speed for 45 mins to n hour then curl up and sleep for 4 or so. LOL. Seriously enjoy and savor every moment you can with them. My youngest is now 22. I dont know where the time has went.

I believe David Tubb recommends putting set screws in the head of the Dillon 550 to take the play out of the turret for loading ammo for long range rifle shooting.

I 'bumped' the underside of my tool head[s] with a center punch to slightly upset the aluminum. Needs 'rebumping' every few years. Although may not be necessary, but it cured my anguish.

I suppose you could install ball detent set screws to accomplish the same thing (from below), as the Walstr suggests. Being spring loaded the mod would be quite long lasting.

If you want a better OAL first start with a milled toolhead from
Whidden Gun Works whiddengunworks.com then install helicoils in the toolhead so it can be screwed down or
Whidden will do this for you.
