What company makes "precision" die bushings?

[Dusty Stevens]

Kinda figured that, what confused me (easy to do!) is why not advertise the fact that they carry them.

They may be too new to advertise until they get under full production

SAC Neck Sizing Bushings

With universal outside dimensions of .500" diameter by .375" height, these bushings can be used in MOST resizing dies. For Example they will work in the following dies. RCBS Whidden Harrells Redding Hornady LE Wilson These will not work in our Modular Sizing Dies or Forster® dies...

This one right here! SAC is top notch! I went from about 4.5 thou runout to 1.5 with the bushing change ONLY! From the ni Redding.

they have been running print ads for the past few months for the micron bushings...

I've had better luck with Whidden bushings

 

[tac284]

There used to be a little company called CRT, I believe someone bought them out?

Whidden

 

[dgeesaman]

You might want to talk with Whidden and his products.

I had by far, the worst luck with Whidden bushings. The chamfered edge shaved brass and they all weren’t the size on the label. And since I was working with a full set of 6mm bushings I think I had a representative sample.

I verify the ID of each bushing regardless of manufacture or size stamped on the face, I’ve only come across one bushing that sized differently than marked and it just so happened that my set up liked it.

For the cost of those bushings you can get a lowly lee collet die and go to 1 thou without even trying!

Good for you but I've never been able to. It's like rolling dice, you never know with Lee what you'll get. I'm not going to purchase and return and purchase again hoping to get one, I've gotten several of the SAC and all are within .001 for runout, the 6 Grendel I think the problem is/was in the die now but for 1/2 of a thou I'm not getting a new die.

limited sizes

But if you don't advertise what you have then you are telling shoppers "I don't have any" and you sure won't sell any of the limited sizes that you do have.

That is the very first time I have ever heard of any problem with Whidden's bushings or any of his products. Did you call and talk too John about them ?

I did not. I got them on sale and added them to a die order, so when they did not meet my expectations I moved on. I have Benchrite, Redding TiN, and RCBS WS2 now. The Whidden are lower cost than most, are stocked in a full array of sizes, and probably serve the entry level well, especially if you inspect the as-sized brass instead of rely on bushing labels. (Bushing error is but one of several reasons to inspect brass after changes in sizing).

I think with bushings we all have our own expectations and few have the resources or tools to comprehensively inspect all critical characteristics. But given that this thread was about the highest quality bushings, I felt compelled to raise my experience. If anyone wants I still have my measurements. One of these days I might put the bushings I have on our CMM at work and validate their cylindricity, squareness, and size for additional data.

Well there you go.

 

[ChrisNZ]

Yep, I understand sizing is dynamic. That said I want bushings that are consistent. It feels like you get way too much variation from the "off the shelf" bushings. Making up numbers here, but I'm tired of sizing with a .267 and getting .268, then dropping down to a .266 and suddenly my brass is coming out .262.
..

Well, that might not be fully due to dimensional differences in the bushings. You are assuming there is a linear relationship between the dimensions of the bushing and the produced result. I would suspect that there is a threshold where when you exceed the yield point of springiness, you will get a greater than expected shift. Any metallurgists about?

If you’re sizing, you’re yielding. If you manage to feed your brass through a sizing operation without changing its dimensions in any way, you didn’t yield and the brass sprung back completely.

Well annealed brass should follow the bushing size with some consistency. The spring back should be similar for all bushing sizes that actually size the neck. But things don’t always follow theory.

But for fun I should do that experiment sometime with a couple pieces of brass and bushings of precisely measured ID.

I have used Wilson, Forster, Redding, and Widden bushings all with no problems. Mabey I am just lucky or less picky.
