Fits All Powder Bar Sizes
Also fits SL 900 Powder Bar and Shot Bars! *

Much more than just a dial or knob … the Micrometer Powder Bar Kit™ replaces the original 1/4-28 adjustment bolt with a true precision micrometer with 40 threads per inch. You will be able to return instantly to any powder weight setting with a speed and an accuracy never before possible. Of course, you still must weigh and confirm all powder weight setting changes.

† Powder bar not included.


FREE Calibration Curve Spread Sheet

Calibration Curve
(Click on chart to view larger)
We provide a FREE Excel spread sheet you can use to generate "calibration curves" for each of your gunpowders. With a "calibration curve," you can predict the micrometer setting to give you any desired charge weight for that gunpowder.*
* You still must weigh and confirm all powder weight setting changes even when using a calibration curve that you have generated yourself.
Q: Will this spreadsheet work with rotary drum powder measures (e.g. Redding, RCBS, Hornady, Harrell's, Lee) that have micrometer adjusters?
A: Absolutely! But, as always, you'll need to generate a new curve using your powder measure and gunpowder of choice.

Powder bar MicrometerThis is a must have for your Dillon Machine!
I am constantly changing from loading 9mm Major to 9mm Minor.
Effortless to get spot on with this device.
In addition i load multiple calibers and find myself using the 1 powder thrower with the micrometer on it instead of using my other throwers. It is so much easier to adjust.
Highly recommend picking one of these up!

This Thing is Dead On.This powder bar is awesome! I followed all instructions and this thing is dead on. Thanks for making such great products. I should have done this along time ago. Written by Gerard M. on Mon 24 Jun 2019 9:00:26 PM GMT
Holy cow batman! This device is awesome!I have a Dillon 550B which I installed the Powder Micrometer on. After installing it, I decided to use the calibration spreadsheet. I spent 10 minutes dispensing W231 powder at different settings and entering the data into the spreadsheet. And then I was ready to try it. I wanted 5.9 gr W231, entered that into my spreadsheet, found out that I needed to set the micrometer to .92. I did that and I dispensed 3 charges to verify that it was correct -- it was exactly 5.9 gr! This thing is amazing! Prior to this amazing widget, it would take me 15 minutes trying to turn that stupid little bolt on the Dillon powder dispenser to get the powder charge I want. Now it takes me 30 seconds -- 25 seconds to find a flashlight and 5 seconds to set the micrometer!

I highly recommend this!
