Best Powder Measure??

For rifle loads I've been using the RCBS Uniflow for more than 35 years.

It may not be the best, but it works well for me!

For handgun ammo my favorite is the Lee Deluxe Auto Disk.

I'm fairly sure that I own at least 5 of them. Again, they work for me.
 
I load pistol and revolver only. My Lee AutoDisk works perfectly for me. I check every tenth (or so) drop on my scale, and they are always correct. Years ago, I had an RCBS and it was a bit inconsistent on low-volume target loads.
 
I've used Lyman55, RCBS, Lee auto disk, and Lee auto drum for different applications. All are accurate and repeatable.

The major reason for any powder measure's accuracy and repeatability is the use of a powder baffle!
 
For light target loads I just dump powder from the long "Tube" and check the first settings and the every 15th or so after that.

For maximum loads I weigh each load on the old 505 balance beam, just to be on the safe side.
If new to the game I might go with the elec. scales but it's too late in the game for that now.
 
I have 2 Belding and Mulls that I have used for 40 years that work great. I also use a 550 Dillion a RCBS Uniflow and a Lyman that work good. The Belding and Mulls are the go to for my rifle reloading.
 
Never used a Harrell, but I'd sure like to see one in action. I have a Redding Match 3BR and another Redding Competition 10-X. I keep one set up for pistol/small rifle and the other one for larger rifle. I'm very happy with them. Built solid and very accurate. I know they will both outlast me. The only powder I've found that won't meter consistently from them is the little Trail Boss cheerios. Very accurate with ball and flake powder.

Lots of measures I've never used, so this is just one mans limited experience. So many choices...
 
I had 7 Lyman 55s for many years..2 now and a Belding and Mull. Had about every measure you can name...including Harrels. The 55s were better than both of the Harrels. All the measures were good with some powders...the Lymans were good with most. The Dillons are especially good with Ball powders...but most are. It's just that the Dillon is attached to a very good (progressive) press. Yeah I still have RCBS and Reddings even a Herter's that I use every now and then. I ought to sell all the Pacific Hollywood's and others I haven't used in years. But, they all work. Some better than others
 
You said best with no qualifications...
then the Prometheus is the best...period.
That was true with the original, and presumably even truer with the present one. I have an original, and it is simply weighing charges with close to the speed of a simple mechanical powder measure.

Either one will cure you of complaining about the price of a Harrells.
 
For all of my HG loads, I use the LEE Adjustable Charge Bar on my LEE Turret Press. This thing is very precise. Just make sure that you let the turret cycle each step back to powder fill. The spinning motion levels the powder and lets the adjustable charge bar do its thing. I consistently get better than +-0.1gr, and more like +-0.05gr more often than not. I always double check with my RCBS #505 balance beam every 10-20rd.

For rifle rounds, I use the LEE Dippers to get close, and then use my Redding Trickle on my RCBS #505 to zero in on exact charges. Slower, but what better way to enjoy reloading, IMO. ;)
 
I’ll disagree based on my experience with all the measures I’ve used and the two Lyman 55’s that I continue to use, neither with a baffle.

I've tried measures with and without baffles. My results have always been inconclusive. Firmly settling a full measure before loading any charges seems to be at least as important as any other factor. I throw about twenty charges before fine tuning the adjustment. As the reservoir becomes somewhat depleted, I usually adjust the setting again whether I'm using a baffle or not.
 
Some years back, I had a Lee 1000 Progressive that used a disc system powder measure - don't know what it was called. It was surprisingly accurate and consistent and probably inexpensive.
 
I'm using an Ohaus that was a spare given to me by the friend that started me in handloading 15 years ago, use it for pistol only Also have a Redding that I only use for rifle loading, bought it used at a gun show about 12 years ago. both are very consistent and have served me well
 
The differences in powder measures could be the OPERATOR. Consistent powder drops require consistent utilization of the powder measure. Varying the "procedure" can result in a very inaccurate powder drop.

My RCBS will consistently drop powders such as 231 or Accurate 5 & 7 with less than a half a grain differential. But, when you get to the rifle stick powders any volume measure will have differences.

A guy can spend a lot of money. But few actually test their setup. I've tested the Lee Perfect and it is excellent with the powders it likes. I've also tested the Lee Deluxe and it likes more powders.
I've been using the Lee Deluxe for the last year and am quite happy with it.
 
Not sure of any best or worst, but saw a write up for this one and found it nice, small footprint and it got a good review. I am back in the dark ages using powder scoops, but I think when get back to reloading in a few months, may check a few more reviews on this one. Anybody have one yet??
