I am looking for a powder trickler that releases one powder kernel at a time.

Boyd,
With all due respect to you (and I really do mean that), the =/- .1 grain variance you mentioned which doesn't concern you nearly as much as the other pertenant factors that you listed, is the acceptable factory standard deviation in many scales, digital and beam alike, as with the commonly used American made Ohaus 10-10 for example. I agree with you that with all other shooting factors being the same, a 1/10 grain powder difference (which is the equivalent of 6 kernels of H4350 powder), from one shot to the next often will not produce any noticeable difference in shift of POI on a target. HOWEVER, what does concern me are the many instances over the years that I have encountered a scale momentarily metering out an errant charge, which upon my double checking it, was found to be off as much as 3/10 grain or more. That will certainly more often then not spoil an otherwise tight group. The point I'm making is that many of us who are striving for tight bench groups are already taking the time and effort to be sure our charges are being weighed accurately on our scale, and we don't find it takes all that much more additional effort while there already, to adjust it up or down a kernal or 2 to make it perfect. I hope this makes sense to you.

I was not discounting the desirability of uniform powder charges. I was putting that factor in its proper place in the order of importance FOR THE DISTANCES THAT I SHOOT. Obviously as the distances get longer, this factor rises in the list to a considerable degree.
I shoot at shorter distances, and cannot tell you how many small aggs that I have seen shot with thrown charges. As to scales, not wanting to fork over for a magnetic force restoration scale, and finding lesser electronic scales to be a pain to trickle with, I use TUNED balance scales. The latest one that I did, shows progressive deflection as individual pieces of Varget are added, as displayed with the use of a web cam.
With regard to thrown charges, if the shape and size of a particular powder do not allow me to stay reliably within +-.1 grain, I throw light and trickle. I guess that what it comes down to is that I find it common that because of their reading on the internet, I run across fellows who are placing great emphasis on little things, and ignoring more important things, for the kind of shooting that they are doing.
At short range (1-200 yards) spending time worrying about single grains of powder is a complete waste. On the other hand, for 4350, because I cannot throw it to my standards, no matter what the distance, I throw light and trickle. Recently I have been doing some load testing for a 6.5x47 barrel and doing some loading with H4350 that I weigh as close as I can get it, because if I am going to weigh, why do anything less. The powders that I normally work with, I can throw.

I am fortunate to have a Prometheus II, I will never regret the investment. Once you are up speed on the operation , I can charge, seat bullet, and be ready to throw another charge by the time you finish seating , bullet, about 12-15sec to within.01 accuracy. That's 10 times better! Don't give me crap about being rich to buy one, or my favorite the Idiot that asks if it cuts kernal in half. To be that accurate. No haters please! Just giving info! JVON

Now that would be (is) funny if it wasn't all so true. Later! FrankLapua40X said:Mega said:

You're either a new shooter or you've got some pretty awesome ear protectors.

I'm not sure if this is American Jest or you are serious.
I've been shooting for like 50 years, reloading for most of that and I do have Tinnitus but that doesn't stop me from hearing a single powder granule drop into the scale pan...seriously. Quiet atmosphere means rural property, no sirens, traffic or whatever... birds chirping perhaps breaks the silence....

It is based on a very finely made balance beam scale.
The trick is in the automatic control of a trickler that is the most complex that I have ever seen. It reminds me of a miniature version of a progressive reloader's automatic case feeder. I understand that ball powder can be a problem.

The Prometheus is definitely a work of engineering art, but is it truly worth it money wise compared to a GD503 or FX120i? I saw the videos, its not any faster than throwing AMD trickling up on a magnetic force restoration scale. And with the limited powders that work with it is a HUGE limiting factor. I simply don't get it, lol.
