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.

Customer Feedback
"I just installed my first micrometer kit yesterday and just got done testing it. Very nice! After entering sample weights for the 0, 1, 2, and 3 measurements I used your spreadsheet to get a setting for 18.7 gr of H110, dialed it and weighed 10 charges … perfect! I'll be buying another kit for a large powder bar to load .223/5.56! I use two different powders and load five different bullets for 300 AAC Blackout using a small charge bar. This is going to be a serious time saver!"

"The Micrometer Powder Bar Kit in combination with the Precision Powder Baffle, allowed me to finally get consistency in my Winchester 231 loads. My chrono velocities now come in at less than 20 feet per second standard deviation and 3.5 power factor standard deviation! No more worrying about making Chrono at my USPSA matches."
— Rob C. - Cody, WY

"I have fairly recently purchased your "improved " powder measure bars for the Dillon 550. I installed one and had you install one. I have just started using the large powder measure bar and all I can says is. "why did I wait so long to make the change." I used to hate changing calibers or bullet weights because it would take me so long to reset the powder throw weight. After I calibrated the bar with the provided chart, it's a piece of cake. Thank you for a great product."

MAKE YOUR LIFE SIMPLE!!!I have the micrometer powder measuring tool installed on both my pistol and rifle bars. It takes ALL of the guess work out of measuring powder. Once I have established a load, I save the reading on the micrometer on my phone in notes with the powder type along with what caliber I'm loading. Just set the dial back to that setting andI am usually within 1/10 of a grain.
It just makes life simple.

Dillon Powder Thrower Good. Uniquetek Micrometer GREAT!Lee—
I have to say, the consistency of the powder throws with micrometer / 40 tpi screw and powder baffle is remarkable. EVERYTHING— that is, ALL of the calibration check loads ( 5x the 5 settings for 5 full rotations of micrometer dial,) from smallest possible charge up to 7.1gr of AA#5— was within .05gr. Returning to any given charge setting resulted in the exact same amount of powder being dropped within one test charge. Charge weights were nearly 100% linear from 3.3 to 7.1. I’m very pleased with this setup. Big thanks.

A Must if you load multiple calibers or Bullet weightI have the micrometer on my 3 Dillon powder measurers and it is a time saver moving between different powder recipes. I'm using Hogdon CFE Pistol which is very fine powder and I use the numbers on the micrometer to go back and forth between load distribution. I still re-weigh but its spot on each and every time ( you have to use the same powder). My only regret is I paid shipping 3x when I should have gotten them all at once. If your smart enough to reloading you can get just the kit and put it together yourself. Written by Tom P on Tue 4 Jul 2017 4:30:47 PM GMT
