    Lee Auto Drum... first impressions

    Got my Auto Drum & set it up for .454 Casull using H110 powder on my Lee Classic Turret.

    Cliff's: Simple, easy, seems reliable enough but I'll be watching it closely & weighing often. I'm satisfied with it so far. It has it's quirks.

    As with most Lee accessories the cheese factor is heavy. Lots of plastic & wiggly bits. The hopper just sets down into the cast body. The on/off is slick and positive though. I made a label for "Off" and "On" since the body is not marked.

    Removing the disconnector took all of about two minutes, and half of that was getting a screwdriver.

    Yes, you need a riser if useing with the Auto Prime on a Classic Turret.

    Setup & adjustment was dead easy. When you lose the adjusting tool it appears that a regular hex key will work.

    After throwing a dozen or so loads of 25-ish gr of H110, weighing every charge, I started getting variations of .5gr or so. Disassembled & found the cast body to be loaded with powder.

    Turned out the powder was actually fused into a coating on the body. Best I can figure there was a coating of some sort (I would guess a preservative?) in there and it reacted with the powder. Cleaning the stuff it came out in sheets & chunks.

    Reassembly was fairly simple, though the little arm that actuates the drum rotator can fall out of place & you won't be throwing any powder. And don't over torque the little plastic nut that secures the drum.

    After loading a few dozen rounds with 23-29 gr of H110 I've been finding mostly within +.2gr and an occasional +.3. This measure looks as though consistancy is key. You need to do everything the same every time.

    The mechanical movements are visible during operation. You can see the actuator move & the drum rotate so malfunctions won't be hard to spot. I'll be watching things closely and weighing every charge.

    Overall I'm happy enough with this measure. For any sort of volume I'm gonna be using my Auto Disc though if possible.

      Got my Autodrum and been loading 45acp with W231 and no problems at all...I like it...I'm an old guy that has not used measures..only dip and trickle into my beam scale for lots of years...thought the autodrum looked ok and was cheap so got one...and like it a lot..I won't use it for rifle loading but think it's fine on my Lee Turret for handgun loading.

      Mine was clean and has stayed pretty clean...it's got quirks as stated...the little lever that "sets the load" is there to prevent double charges on a progressive and it serve the function to "cock the measure" on a single stage or turret press...so you can get a squib if you don't use it every drop with the single stage or turret. I disabled mine as it's on a turret so it will now drop without having to remember to cock it...also when you are done and go to dump the powder back into the bottle...got to remember to shut the hopper off (I also made labels)...and the body of the measure holds a lot of powder so be careful when you handle it (it's easy to miss and spill a bunch of powder...don't ask how I know)...and as said..don't overtighten the nut and plate that hold the drums in place.

      Mine has proven very clean to use (no "lee leakage), reall accurate, cheap and works fine for what I've used it for...instructions are typical Lee...sort of all there but you got to dig for them....
      God and the Constitution give me my rights and actions...any other input is just blabbering.

        I got the auto drum for my Loadmaster despite that it comes with the Pro disk powder measure. To add to the OP post, here are my impressions:
        - Hopper did not set tight to the cast body. I added a piece to painter's tape to fix that.
        - The on/off action was a bit sticky so I loosen the screw 1/8" of turn
        - I wiped a drier sheet into the hopper and the inside of the cast body and drum to reduce static.
        - When the drum get cycled, it never fully returned to fully open; probably about 80% open. I noticed that the mechanism has a lot of slop. In order to fix that I loosen a bit the retainer knob until there is no bind. Granted I had to watch for any powder leaks.
        - On the load master it uses a chain to reset the drum. So far it works but I found out it did not deactivate when cold (40-50F) I could trow double charge. Perhaps got worn out? I doesn't matter to me since I am always looking at the case before set a bullet.

        I have use it with Win WSF, Accurate #7 with no issues. I spotted a few grains on top of the press, but it was most likely I spilled a bit trying to return some powder back to the hopper.
        As far as accuracy, 50% of the time is right on; 20-30% are +-.1grain and 10-15% +0.2 grain
