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.
— Kit includes: Micrometer head, Loctite® and installation instructions.†
† Powder bar not included in kit.
FREE Calibration Curve Spread Sheet | |||

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 Q: micrometer adjusters? A: Absolutely! But, as always, you'll need to generate a new curve using your powder measure and gunpowder of choice. |

It is Free to use.
