I started with a Lyman 55 powder dispenser, then a Niel Jones conversion, then a Harrell's BR dispenser. They all throw in approximately the same accuracy range, & all not as good as I would like.
I have a Pact scale (0.1 gr resolution), a RCBS Chargemaster (0.1gr resolution), A Gempro 300 (0.02gr resolution), and now a A&D Fx120i with the Autothrow and Autotrickler (0.02 gr resolution).
The OP wanted accurate and fast.
The A&D package is the fastest, most accurate and most expensive. Drops a load in 10-15 seconds. $950-$1000 I recently got it, I only wish it was available 40 years ago. It is my "go to" scale now. The scale alone is $500 This is a laboratory grade " force balance" type of scale, not a strain gage scale.
The Chargemaster is accurate to 0.1 gr, and is slower, takes 30 or more seconds, and overthrows or underthrows occasionally. You must wait for the "beep" at the end to see if it is in range. It is medium priced. Midway has them at $350 but there is a RCBS $100 rebate, so say $250. I still use it when I am reloading at the range. Tuning the scale and feed tube will help.
DO NOT confuse the Gempro resolution performance with the A&D. The Gempro will drift a lot, and the A&D is ROCK STEADY. The Gempro is $150. You cannot buy A&D performance for $150
The Pact is typical of the strain gage style scales in the $30 to $100 range.
So the low cost scale is faster than your Beam scale, perhaps a different brand would work better. The GemPro will take a lot of care to account for the drift. The next step up is the Chargemaster, which I would recommend to you if you feel that accuracy in the .1 range is OK for your purposes. If you need better, then the A&D is the answer.
Note:
I always turn on my Pact or Chargemaster and let it warm up for 15 to 30 min to help stabilize the readings and prevent drift while measuring. The A&D also says let it run for 15-30 min, but It seems to be stable right away.
As to comments on a lot of threads that you can't get near fluorescent lights, cell phones, and electronics, I have an overhead 2 bulb 8 foot fluorescent fixture immediately above my reloading bench, another next to it and another 5 feet behind me, and my cell phone is in my pocket when I load, and the A&D and the Chargemaster and the Pact all work fine. I have a ferrite choke on the power supply to the Pact and the Chargemaster, but NOT on the A&D which is, as I said rock stable.
I hope this information will help you in your choice of scale.
ps CE and Autotrickler are great companies to deal with, and the Autothrower is the best thing since sliced bread.
