Bushing ?

[chuckw2]

Wilson or Redding...Which do you use? Is there any difference?

Chuck,
I like the Titanium Nitride coated ones Redding makes. The only thing better is carbide but they are very pricy and not available in all sizes.

Chuck, the Wilson bushings have a .0005,half thou.) taper on them, so you can flip 'em around for a bit more or less tension.

I use the Redding standard steel bushings. I have a few of the TiN coated ones, but I like the steel ones better. -Al

Redding instructions advise inserting bushings with the size marking down; Wilson does not say. Should the Wilson bushings be inserted up or down to accomodate that additional .0005 tightness??

Down for a little more squeeze with the Wilson.

I've always used the steel Wilson bushing with no drawbacks as far as I can tell. The reason Redding suggests the bushing be inserted in upside down is that they think it possible to introduce runout when the stamp on the bushing contacts the bottom of the decap pin holder. Ive never tested the theory.

This is my problem with Wilson bushings.....You need the Hubble telescope to read the numbers....

Chuck ...I have the same problem....so I just write on the side of em with a magic marker....and also use colored ..,,red-yellow-green-black-etc. ) to mark the ends so I can easily tell at a glance what they are .....this gettin old aint for sissys.......OBTW ...measure the Redding bushings...they arent always what they are marked....I like em but got to check em....the nikel metal tungsten hyper glyride or whatever they call it this yr...is sliker and causes less wear and scuffing of the case necks...Roger

My Redding Ti-coated bushings have a very slight bevel on the "printed" end and a sharp edge on the other end. The instructions clearly say to insert them into the die with printed end down because of this bevel. When inserted upside-down, the neck will be .0005-.0010 smaller with my 6mm and .224 bushings.

My calipers are not precise enough to make absolute measurements, but my three 6mm bushings are definitely larger just inside the bevel than at the other end -- probably something less than a full thousandth. I can feel the difference when sizing a neck if the bushing is upside-down.

As far as run-out, nothing I've tried will equal a Lee Collet die for low run-out. Guess it's because the neck is squeezed against a mandrel that is being held straight by the flash hole, but run-out with turned necks is just about negligible. But my Reddings sets are very good especially with the bushing loose enough to float a bit, maybe a 16th of a turn or so. Keeping the bushing and the inside of the die clean is also very important to good run-out.
