Lee Auto Drum Powder Measure - Now Available

[golfhack]

Just ordered it from Titan Reloading ($35), now in stock. Could not resist, looked too interesting - two infinitely adjustable drums included (large/small) for charges ranging from 1-80 grains. Case activated measure, looks like I can directly install it on top of my existing powder-through expanding dies. I'm currently using a modified Lee adjustable charge bar, which works OK, but it has a bit more variation than I'd like with small pistol charges. Curious to see if this will work better.


There are videos from Lee Precision up on YouTube now too!

Has anyone else tried it yet?

[dragon813gt]

I've been waiting for this since they announced it. I checked for availability on Wednesday and it wasn't showing in stock yet. I doubt anyone has one since they are newly released. I ordered one along w/ one set of extra drums. I'm hoping it doesn't leak H110 like my PAD does. If it doesn't leak and throws consistent charges I will be extremely happy.

One of our members (Lee Reloading and Casting Equipment Group) on FB has posted a review and video. It looks very promising!

Just ordered one myself. I've been using an RCBS Uniflow case activated on my Classic turret it's a bit heavy but works. I think this new Auto Drum will be less stressful on the auto indexer.

[Bzcraig]

What the heck, it's just money, right?

[VHoward]

For $36, it's worth a try. I'd be interested in your opinion on the quality of the unit when you get it. Die casting quality especially. For $15, you can get extra drums so you can have one set for every charge you have. Lee seems to be cashing in on their Classic Cast line. They have an awesome product in their Classic Cast single stage press which I have one of. Every bit as good as the RCBS Rockchucker.

Received it today. Below is the picture from the box:




It ships with the small drum already installed. Two adjustment keys are included, one for each drum. Nothing really to put together - all I had to do was remove the Pro Auto Disk unit from my Lee Classic Cast Turret and screw in the Auto-Drum. Fit and finish is typical Lee - the die cast body is pretty rough and the open/close valve for the hopper was loose, even after I tightened the screw. Plastic parts look/feel cheap - but as long as it works I don't really care.

I had some TiteGroup on hand, so I used that for the initial testing. Very quickly ran into my first issue - the disconnector. Lee ships the unit with the disconnector already installed. Even though the measure is case-activated, you have to ALSO manually press the disconnector button EVERY time to actually dispense the powder. I guess this is a safety "feature" but it is easy to forget to press the button. I think this actually dramatically increases the risk for squibs. Thankfully, the manual includes instructions for removing the disconnector, which is pretty easy to do. Once removed, it works just on the case activation.

The powder hopper seemed to have quite a bit of static electricity (need some dryer sheets), but I went ahead and tested anyways. These are my measurements for 10 consecutive charges (I cycled the turret before each charge):

• 3.82 gr
• 3.80 gr
• 3.70 gr
• 3.70 gr
• 3.72 gr
• 3.76 gr
• 3.82 gr
• 3.80 gr
• 3.70 gr
• 3.84 gr

I suspect it will do better once once I clean it out and wipe it down with some dryer sheets, but it seems at least as consistent as using the Pro-Autodisk adjustable charge bar. And, I did not see any evidence of powder leakage (I get a small amount of leakage with the auto disk). Admittedly, Titegroup is probably not the toughest test for a powder measure.

The adjustable drum is a NICE feature to have - I can quickly change charge settings by simply turning the adjustment key. Lee also sells the drums separately so you can pre-set the drums and simply swap them out as needed. However, when installing the drum you have to be careful not to over-tighten it. Found out that if I tightened the clamp know too much, the drum would not consistently rotate back to the same position. Not a huge issue, but something to double-check and verify when installing a new drum.

I did find one thing I did not like. To change powders, it is easy to unscrew the hopper and pour the contents back in the container. However, it leaves a significant amount of powder in the measure body - see photo below:



With the auto-disk, all I have to do is cycle through a few times to empty the remaining powder. With the auto-drum this would take forever. I ended up just unscrewing the powder measure and pouring the contents back into the container. A bit inconvenient.

Overall, I like the auto-drum and will use it for loading 9mm and 300 Blackout (can use the small drum for both). The auto-disk will now be dedicated for 45 ACP. If you already have the Pro Auto-Disk and it is working well, then the auto-drum is probably not necessary. However, if you want more granular control over charge weights and want to be able to pre-set charge weights by purchasing additional drum sets, the auto-drum is worth taking a look. For $36, it seems like a pretty good deal.

[VHoward]

Thanks. That was pretty good for a quick evaluation. I bet if you ran an entire hopper of powder through it the first time without using those charges for actual loads, the charges would get more consistant. On the Lee PPM, Lee specifies to run an entire hopper of powder first, then it will measure consistantly. I did that with my PPM and it does work. A wipe down with a dryer sheet won't hurt.

My hope is that it will measure real fine powders without much leaking.

This Auto Drum PM looks to be of the same metering design as the Classic PM which is a substantial improvement of the old PPM. Based on the tests I did on the Lee Classic PM I'm confident it will dispense/meter consistent charges of both flake and extruded powders (like Unique and IMR 4895) if the sector/sun gear mechanism work as advertised.

I'm thinking it will be an unbeatable PM for the 550B and the LM progressive presses as it has a chain link reset with each cycling of the ram.

Hi guys, there is a thread for this measure in Our Town also, I'll post what I posted there.

Hello all,
Got in a little T&E on the new measure.
All in all, I like it.
Clean it well, a little "oily" in the guts.
LOTS static - drier sheet fixed that.
The little collar that you turn to attach to the die is smaller than the one Lee sells for the Pro auto disk.
For me, the "disconnector" has to go (on a Dillon 550), easy to remove, I may play with the chain activator in the future.
The powder shutoff is a nice touch, but it leaves about 70g 231 in the measure (Pro auto disk leaves maybe 10g).
Tried it with 231 and WC820 (very fine pull down powder), no leakage anywhere I could see.
See results below.

Conclusion ? I think like most of Lee's products it's about 95% engineered - screw collar too small, 70g left when removing the reservoir.
Don't get me wrong - I love Lee products, I use their dies exclusively, have lots of their stuff, you just need to be willing to tinker with some of it.

I like it, I may leave the Pro on the 45 acp tool head and use this for most everything else.

Not bad !
These are after 3 cycles to "settle" everything.
I tried to cycle the press as if I was loading - ie the same "bounce" every time.

I have had the same experience with my Lee PPM. If the auto drum works well with ball and flake powders (which it looks like it does) I'm going to pick one up soon

I received mine on Thursday but haven't had a chance to try it yet. Right now I'm getting caught up on my .223 supply but unfortunately mine was missing the rifle drum. I have an email in to Titan and am waiting for my reply. I may have to set up for some wadcutters for my .38 just to try it out. I cleaned it thoroughly and sprayed all interior surfaces down with graphite lube so should work nice. The design seems well thought out and well made. Right now the most difficult metering powder I use is 700-X so maybe I'll just try throwing some charges to test how it works with it.

[dragon813gt]

I tried mine out this morning. I am not pleased at all w/ it's poor performance and leaking. I typed up a review in Open Office but when I tried to copy and paste it here the formatting was screwed up. When I get home from hunting I will post it.

[1bluehorse]

Mine showed up today. After a through cleaning and then running a hopper full of powder through it I did tests of ten powder drops using BLC2, Herco, and IMR 4198. It's as consistent with these powders as any other measure I own. (actually much better with Herco than others I've used) my other measures are a Lyman 55, a couple Uniflows, Lee PPM, and Lee Auto discs. Zero leaking. BLC2 is a pretty small grain powder and no issues at all. I think it's a good buy especially if you're looking for a case activated measure that will throw powder charges large enough for Magnum rifle cases. I got mine for running pistol rounds on a progressive press.

[VHoward]

OK. So tracking said it would be here Monday. I got it today on Saturday. I set it up on my single stage for testing it out. Really dislike that double charge prevention feature, but it can be disabled. I also don't think much of the quality of the plastic parts. I wonder what the life span of this measure will be? The main body is cast aluminum. The outside is finished OK. The parts that matter are finished well. The performance is very good. This measure proved to be very accurate and consistent.

Powder was Accurate Arms #9
Target charge was 12 grains
Results of 10 charges thrown
12.0
12.0
12.1
12.0
12.0
11.9
12.0
12.0
12.1
12.0

I then measured 10 charges all together and it came out 120.1 grains.

I then went ahead and cycled this measure until there was half a hopper of powder left to see how much leakage there would be. AA #9 leaks the most for me and there was a very small amount of leakage with this measure. The leakage was 1/4 that of what I get with the Dillon measure.

I am pleased with the measure over all. Now to see how long it will last. The plastic parts just feel brittle to me.

I did all this without dis-assembling it to clean with anything or treating it with graphite. Straight out of the box onto the press and tested.

[mwells72774]

I wonder if someone could 3D price the weak parts with a higher quality polymer

[r1kk1]

The leakage was 1/4 that of what I get with the Dillon measure.

I never had one leak with #9, or 110/296.

I remember a Vectan powder that was as fine as 7f. That 1 lb caused me grief.

Take care

Initial testing with HS-6 not as good as expected.

Powder drop accuracy was on par with the autodisk, but it actually leaked more powder than the autodisk. Looks to be migrating through the labyrinth groove the drum rotates in. Tried tightening that until it started impacting the return rotation of the drum - still leaked.

Everything is cleaned and wiped down to reduce static. Tried dusting a bit with mica as well.

I'll have to play with it a bit more when I get time.

[flashhole]

I've been a huge fan of dippers for lots of years but the Auto Drum write-ups have been pretty favorable. Just ordered mine today from RS reloading along with the rifle charging die kit (both long and short dies). They have the two-die kit on sale for $11.99.

I plan to use it for 221 Fireball, 223 Rem, 40 S&W and 45-70. My expectation is it will work well with the powders I use.

Has anyone purchased more than one and outfitted multiple presses? They're sufficiently inexpensive to have one for each dedicated setup. If it works out well I will likely pick up a second unit and have one for small drums and one for large drums.

[35remington]

Does this measure not have a shutoff valve included to separate reservoir from drum like the Perfect measure does?
