Harrell’s Powder Measure Help Needed

[hpshooter]

Thanks that what I'll do.
I did notice a few times it would clog up and not drop all the powder. I raise the arm let it make a slight tap and then slowly lower it...
I'll go back out in the shop later and throw some more chargs..

Have the identical measure with regard to the metering adjustment. Some powders will bridge the end of the drop tube especially if you are fast with the downward travel of the lever. As stated above, a couple light bumps at the bottom of travel helps prevent powder from hanging at the top of the tube. My drop tubes have a long gradual taper on one end and a short steep taper on the other. Measure is less prone to bridging if the long gradual taper is at the measure end of the tube.

Not sure if any instructions ever came with them. Picked mine up at Harrell's shop and waited while it was assembled from a fresh run of parts. (at least 30 yrs. back) I just adjust to get the charge I want and write the numbers down.

I'm noticing the powder bridging up on the inside everg once in awhile. I'm not talking bout the tube unless it's at the very top where It screws in. After 3 or 4 throws one will drop with very lil powder, then the next will be more than a case full.
Is it in my powder throwing technique

Being consistant is very important, but I never tap the handle up or down.

Most likely. It's a learning curve on the method you use. Dumping too fast will cause this.

Lkwebb,
The best man I know on a powder measure like the Harrells and who helped me immensely when I was loading for a 6ppc is @BoydAllen if he doesn’t see this give him a pm He explains things well and has been doing it a long time. Him and I have spent hours on the phone discussing things like this he a treasure to have in your corner just my .02 worth

Consistency in operation of the measure is key, not necessarily whether you tap or don't tap. Like others have said, I tap because the extruded powders don't flow well and can bridge at the top of the drop tube.

This one has 6 clicks between each number

We refer to this as a 6 clicker, meaning there are 6 clicks to a grain of powder. That is what mine is. Some are 4 clicks. The 6 is more preferable for fine tuning the load.

Rather than a cheat sheet with “clicks and numbers = grains” I make a graph from thes numbers. So 52 + 3 clicks becomes 52.3 . Each powder lot gets a graph. I set the “ Major increment” on the X axis as the number and the “minor increment” as the number of clicks between numbers. The graphs are kept in my range box. Most powders are pretty linear volume to weight.

 

[Lkwebb]

Well I took the baffle out of my dropper and it made a big difference in consistency of not bridging up..
54 clicks averaged 29.24
55 clicks averaged 29.7
55 +3 averaged 30.1
