O.K..., who'd got one of these little beauties? I guess I've been remiss in looking at Lee equipment, cause' yesterday was the first I'd even heard of this measure. I have a couple of the Disc Measures and have always thought they were a good setup. But, from what I see, (u-tube videos) I want one of these new Auto Drums. Maybe two. Anyone want to buy a couple Pro disc measures? :D They appear to be in stock at a couple places. Think I'm gonna order one.

Read some reviews Horseman; from what every single review I've read is that the measure is extremely sensitive to static and initially the charges are true but after a short period the charges are erratic. Often the charges vary up to 15% as is being reported. I'm interested in the measure as well, but I'm going to wait and read some more reviews before buying. My hope is that the bugs get worked out and repeatable drops are standard.

Addendum; a couple of fellows over on castboolits website have written reviews.

Thanks Sparky, I'll go over and take a look on CB. I went ahead and ordered one yesterday, delivery shows in about a week so when I get it I'll do some tests and post my results here. I have a lot of different powders to test with so should be able to get a good cross section of results.

I await the results.

I had to have one and so far am very happy with it. Had to wipe it out a couple of times with dryer sheets to get rid of the static electricity. Have loaded about @4000 RDS of a few different calibers with 4-5 different powders and it works well!!

I've made some separate posts on my experience with the Auto Drum and a couple issues it had. After replacing the "wiper" it's been solid. Just reloaded some 223 with 55gr FMJ using 25gr. CFE 223 and it dropped on the nut. Weighed every drop and had ONE out of 20 that went 25.1...not a big example but I'd say that's pretty consistent. I was using a Dillon 450 so not a lot of "jostling" of the measure so I don't know if that would make a difference or not. I'm guessing not.

Man, this measure has me bamboozled.....I posted this on another forum I just started visiting but I started with it here so thought I would add to my experiences with it here. Lately I've been thinking of maybe switching out my Pro Disk measures for these 'cause I really like the "footprint" it has on my presses, the ability of larger,easier powder drops and the fact it doesn't leak any powder I've tried so far. That is, after I changed out the "wiper". Actually I pretty much like every thing about this measure....EXCEPT...
I have the Auto Drum set up on my Dillon 450 (this is the press I use for 223)
So yesterday evening I thought I would load up some more "test" rounds using CFE223 powder. CFE 223 is a fine grained powder and "should" work well with just about any measure. And on a previous post I noted that I had great results dropping this powder at 25 grains. (I since loaded 20 rds at 26gr but truthfully only checked a couple of them and they were also good) This time I was moving up to 27gr (27.4 is max for 223, and I'm shooting an AR 556/223) well things didn't go so well this time. Not a BIG swing but it was a consistent "swing". The measure just would not settle in. It would throw 26.9 one time and then the next would be 27.1 or .2, then back to 26.9 then 27.2. Over and over. Checked on two scales. I set up a Pro disk with a double disk kit, two .86 cavities and dropped consistent 27.0gr. So if this thing can't compete with a Pro with a double disk kit I'm sure not going to "exchange" my disk measures for the AD. Bright side. It didn't leak a bit. I'm not sure I'll even use it anymore, I just don't trust it.

Lee Auto-Drum powder measure

I have and consistently use two Lee Auto-Drum powder measures. I have exchanged my old Hornady, RCBS, and Lee Auto-Disk powder measures for the Auto-Drum. I have only put a few hundred rounds through them, 9mm and .45ACP. So far the results have been good. The powder measure seems to be well made and sturdy. While not perfect consistency it certainly is consistent enough for my needs.
One thing I'm going to do is remove all the plastic parts, tape or plug up the cavities and openings, attach it to an electrode, and powder coat it electrostatically. I'll use a directional heat gun to melt the powder so as not to damage the nylon elastomeric blade. I suppose I could remove it but I don't want to damage it. Coating with Powder and baking the pot metal should also help with static charge. Let me know if you have any thoughts on this remedy/process.
Oh, and BTW Horseman, I think the term you were looking for is "Flummoxed" not Bamboozled. :D

Ah, right out of The Big Bang Theory, one of my favorites.

I got one of these Auto-Drum measures for Christmas and have used it a couple of times. I've been using the Auto-Disk for years for my pistol calibers, and also one of the micro-charge bars for use in the Auto-Disk.

I have both a Lee Pro-1000 and a Loadmaster.

I like the Auto-Drum and it's ability to fine tune and preset the charge weight on a drum and just swap out drums for different powders/loads. It appears consistent enough for my pistol reloading.

There are a couple things I don't like about it though, although nothing big or too much of a problem, more kind of annoyances...

1. The hopper sits rather loose into the top of the aluminum. It wobbles a bit while I'm reloading and working the press.

2. The housing seems to wobble a bit when activated. I notice the thumb nut down where it attaches to the die allows for some play in the aluminum housing. This play also increases the powder hopper play I stated in #1.

3. After using and closing off the hopper there is still quite a bit of powder in the housing between the hopper and drum. This isn't as much of a problem if you remove the measure from the die and dump it out, but if emptying it by activating it with an empty case it takes about 10-15 times if using a 9mm-45cal.

As I said, these aren't big problems, but rather small nuisances that I have found.

So jekemi, did you powder coat, and how'd it turn out? Any pics?

It was the first thing I thought of when I got it out of the box, but supposedly pot-metal does not powder coat very well without a good sanding down (something about uneven arcing or ???). Let us know and thanks.

So any progress with this jekemi?
