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.

A Must Have!I purchased 2 of these, the first was pre-installed on the bar and the second was just the micrometer which I easily installed on my own small powder bar for my XL750. It is a fantastic way to make repeatable throws of powder once I figure out the values. Then, if I want to change the powder charge, I just turn to the value I need on the micrometer and I don't even have to bother checking it--it's the exact amount of powder I need. When I change from target loads to self-defense loads or competition loads, I just dial in the charge I want. If you have a loading regimen that requires you to change charge weights, then get this micrometer. If you have even a little mechanical ability, you can install it into the bar yourself, if not, just buy it pre-installed. Written by Sonny Ftr on Mon 2 Mar 2020 11:36:55 PM GMT
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!
