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.

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

It's great!I'm an NRA Action Pistol shooter. We shoot under strict time limits out to 50 yards. Our X-ring is 4". I can't afford inaccurate ammunition! I shoot bad enough as it is so anything that I can do to help is good. I use a Dillon 750 and have started checking my charge bar by verifying the dial setting on the micrometer. This is followed up with weighing some powder drops. I'm not good enough to shoot bad ammunition and this helps me ensure that I am getting the best that I can get. It's well worth the cost. If you're serious about accuracy and want a little short cut, get it. Written by Alex Ragulsky on Wed 24 Aug 2022 4:13:33 PM GMT
Must have productFor anyone who reloads multiple calipers or even powders the micrometer is a must have. I have a list of powders, grains, bullet type, saved on my phone, so I just save what calibrations I need. Dialing in loads on the Dillon has never been easier or more accurate than when using the micrometer. Won’t run my press without it Written by Lucio V on Sun 20 Feb 2022 2:31:31 PM GMT
Super New UpgradeII have been using Dillon products since 1986. I have changed the bolt head adjustment for another that had a large dial on it. It was okay, but not a sensitive as I liked. I've used micrometers since I was 17 and started to learn machining from my future father-in-law, miss that man a lot!
The sensitivity of this new device really improves the powder porer tremendously.
Not the easiest to install, but not the hardest either. Took me a few minutes to get it set, and now I can't wait until my budget allows me to buy 3 more for the other 3 caliabers that I load for pistol competitions.
Adding this to my Dillon 1100 takes it a set above all the other attempts at improving the sensitivity of the powder measuring bar.
Like I said, I'll soon be buying 3 more.
