    I picked up one of these today, It is a brand new product. I want to try some precision rifle reloading. The reviews for auto powder dispensers are all over the map anyway, so I figured I would try out this new unit.

    Did some testing tonight and figured I would post the results and see what others thought of the repeatability and accuracy, and post my thoughts on the unit as it is a new product.

    General Impressions of the unit.

    It is very easy to use. The calibration process is very simple and easy to do with the provided Calibrated weights, which tuck into storage locations on the main unit. The interface on the panel is very straight forward, there is a powder calibration function that trickles out powder at different rates and it calibrates itself to that specific powder. It dispenses powder pretty fast. I didn't use the cover at all in the testing. There is an App that you can use to control the unit from your phone using a bluetooth connection, I didn't have a chance to try it yet, but you can save setups on your phone and recall them as needed or adjust charge weights, start dispensing, etc. The touch screen is quite responsive and easy to use.

    Gripes: The leveling feet need to be about 1/4" larger in diameter so you can easily spin them from the sides to level the unit. They are flush with the body so being a bit larger would make it easier, but not too bad once you get the gist of it. The start button (play button) is hard to push, but not too bad once you get used to it.

    I used some IMR 4831 stick for the testing, I will do some other types of powder when I get a chance. I did 20 samples at 47 Grains, 85.5 Grains, 125 Grains and 10 samples at 200 grains.

    I used Lyman and a Hornady powder scales to verify each throw, which are posted below. The Lyman was right on target with the Frankford, but the Hornady was consistently lower. The Hornady always kind of sucked, which was why I bought the Lyman. I used the Lyman as the "scale of record" to verify.

    Starting with the second set, I re-weighed the samples in the Frankford Intellidropper as it seemed that the charges were consistently under the stop weight. There was no re calibration done after the first run of 47 grain samples. I just plugged in the new charge number and hit the go button.

    It seems to me that the Dispenser is quite consistent in charge throws. It seems to be consistently just under the set weight, but the standard deviation is quite low. You could likely adjust the charge to get exactly the weight you need by doing this and having a calibration offset. The range of variation is consistently about 1/2 grain at all set points.

    Draining the powder was fairly easy, there is a drain on the right rear. It was a little fiddly, but easy enough to manage. I used a can of duster air to blow out the unit after draining, and made a little bit of a mess, but next time it will be neater.

    I have no basis to judge the performance of the unit, the question for people who have used auto dispensers - how does this unit compare to your experiences with other units?

    It really has 0.5gr variation? Is that a typo, and it should be 0.05gr?

    1/2 grain is HUGE, I get less than 0.2 gr out of my volumetric powder measure on my Dillon 550.

    A new product and intro priced. I ended up with the Lyman gen 6 the same way . It was introductory priced
    It’s a very simple unit and a tad slow but I’m not looking for ultra fast , blue tooth , memory or apps. So it suited my needs.
    Digital scales are fickle , play with it.

    A couple of things. the variation from when the unit stopped dispensing was about +/- 0.05 grains and that was using stick powder. I've never gotten <0.2g out of my dillon 650 powder measure with stick powder, have you run a bunch of consecutive throws and recorded the weights from the Dillon measure? I was using two other scales to confirm the final weights for comparison. The variation of the Lyman scale weights was +/- 0.25 grains, and showed that the actual weight seems to be about 0.5 grains lower than the target set weight. I plan on repeating one of these tests but adding 0.5 grains to the target to compensate and see if the actual charge weights are on target. Based on the range of different set points tested and the consistency of the offset regardless of charge weight target, I think it will work. It would be interesting to see if anyone has data from other similar units to compare (using a seperate scale to confirm charge weight).

    The unit hits the same number every time within 0.1 grains, within its specification. I will be testing some flake and ball at some point to see if/what the difference is.

    Great review. IMHO, stick powders are toughest to get a consistent throw. You'll likely see more consistency from ball and short sticks. Dunno about flake.

    OK, that makes more sense.

    Yes, but with ball and flake. I don’t have any data on stick.

    I have a vague memory of getting quite good metering with Reloder 15, but I don’t remember the numbers.

    This seems like the calibration isn’t working. If it were my tool I’d want the manufacturer to fix/replace it with one that calibrates properly.

    See if your pharmacy will weigh your check weights.
    I had a check weight that was off. Then I noticed the little handle screwed off and you could had lead/steel shot to it to adjust it.

    Thanks for posting.

    A dispenser is the next reloading tool I think I am going to get, but I haven't done any research yet. Weighing each charge by hand is definitely the longest step for me in the reloading process right now.

    It's nice that you have a few other tools to compare it to.

    Now they need a auto case feeder/fill for these things!

    Could you tell me the footprint size of this unit?

    I am getting a scale with better resolution (0.015gn) to get better data. When I have time I will also post data from different types of powder.

    It is a 0.001g (0.015 gn, resolution, display is 0.02 gn typically) scale. They are mainly for precious metals, or chemistry labs. I have a 0.001 scale but only reads in grams (not grains), you can do the math easy enough, but who want's to do that? :) There are a couple of scales that resolve down to that level, and have grains as units like these;

    ScalesGalore - Scales for ALL your weighing needs!


    And you can find some lower cost scales with that resolution and grains for units if you look around.

    I,had a scale from a closing pharmacy. Thing was very accurate and also very touchy. If I left it on all the time it was ok. Although humidity and temp swing in my basement gave me fits a forget trying to get a stable read out with out putting the cover on. The control pad burnt out and I sold it to someone looking for other parts. It was a old Hause? Sp?

    Probably an Ohaus scale.

    Yes that’s it. I could not use that scale when kids where home. It would wonder every time kids ran across the floor upstairs.
