Thoughts On The Hornady Case Activated Powder Measure

[docbrown]

Looking for experiences with the Hornady case activated linkage for their powder measure. I have been using the Lee micrometer with the auto Disk PM, but I have an RCBS Uniflow and a Hornady Multi-Deluxe PM and need to add a couple of calibers to my turret press. Any thoughts, cautions, gotchas? The autodisk/pro is cheaper, but the RCBS and Hornady PM tend to be a little more accurate (and more expensive). Thoughts?

I use the Hornady case activated system on a Hornady L-N-L progressive, RCBS Pro 2000 progressive, and a Dillon BL550. I use a modified Redding 10-X powder measure and an RCBS Uniflow with the Hornady case activated system.

The only problem that I have experienced is I need to spray a little dry lubricant on the sliding parts of the drop system. It gets sticky at times and the return spring is not strong enough to always return the powder measure to the lower position.

A side note, I do not use the Hornady drop tubes to expand the case mouth of my cases. I expand the case mouth with a standard mouth expansion die. I started making my own drop tubes so that I did not need to adjust the powder drop system with each cartridges change. It did not work out as well as I hoped but I found it was easy and quick to adjust the powder drop system when making a cartridge change.

My homemade drop tubes do ot expand the case mouth.

The Hornady drop tubes work just fine though.

The Lee Auto Disk pro and Auto Drum work well for me except for fine ball powders like H110 and #9. For those, I will use an RCBS Uniflow without case activation.

I use to use Lee equipment including the auto disc measure and later the autodrum. While both measures were plenty usable I made the change to Hornady equipment a while back and like the Hornady powder measure way more. Much more solidly built and no leaks even with very fine powder.

I use the Hornady Case-Activated Measure on my LNL Progressive. It works, just fine. When adjusting to flare and drop, it takes some time to adjust so that it's flaring just enough and completely cycling, but it's never been a problem that a few minutes patience couldn't solve.

I don't know if I'd attempt long rifle powders through it, but it's fine for flake/ball/short pistol powder.

I have Lee, RCBS Uniflow, and Hornady powders measures and the Hornady, without a doubt, is the most accurate of the three measures, with pistol powders.

I don't have a Redding to compare against, I wish I could justify buying a 10x but I just can't right now. I don't use a free standing powder measure any more. I use my Auto Charge for that now.
My Lee Pro Auto Disc measure is no slouch either for accuracy but it's dedicated to my .357 mag press because one of the disc holes measure my BE-86 to where I want it.
I put an adjustable metering slide in it but it is old and spiteful so I had to take it back out and go with the original discs that came with it.

Hornady powder measures are really good, accurate, measures.
