All the electronic powder scales list the accuracy as +/- 1/10th of a grain, regardless of price.

What have you found to be the most accurate electronic powder scale, based on your actual use.

Most people don't want to accept it, but powder scales just aren't going to be more accurate than what you're finding.

The bench rest shooters tend to gravitate to the Acculab VIC 123, which is a +/- 1mg (.01543 gr) scale, but they cost around $235 and I believe they have been discontinued now.



I found another 1mg scale that's a little cheaper in the My Weigh Gem-Pro 250 at $153.

Wow. Don't want to do your weighing under a Air Conditioning vent with one of those!

The covers take care of that part pretty well. I also aim the A/C so it doesn't send drafts in the direction of the scale.

Bench rest shooters actually take the VIC 123 out where they are shooting, so they can load and shoot. The bubble level on the back helps too.

Paul,

Nice set up. Imagine separating cast boolits.

I see no need for that closeness in any rifle round I load....

I use a combination of scales.

To weigh and dispense powder I use Lyman's 1200 DPS II upgraded
with the speed option.

For checking that the DPS and my powder dispensers are correct, I
use an RCBS 5-0-5 beam scale.

And for sorting cast bullets I use a cheap Harbor Freight made in
China pocket electronic scale.

All claim to be good for 1/10th of a grain but I don't push the max so I
feel good about what I use.

STCM(SW) has it: ALL of them are more than accurate enough for reloading purposes. Unless you get readouts that vary more than a few tenths of a grain with the same weight weighed multiple times, you are good to go.

You also don't need laboratory-grade check weights. Pick one match grade bullet close to the charge weights you usually use, and use that same bullet as your check weight. I had a match 52-gr HP that I used for many years, for example. Kept it in a plastic bag labelled "52.0 check weight" for twenty years until I got a digital powder dispenser that came with test weights. Might still have that bullet around here somewhere.

Weighing powder charges to a hundredth of a grain is like trimming firewood with a caliper: utterly pointless.

I agree, I still use my old rcbs 5-0-5 and have for many years and like Rocky said, I also have a 50gr bullet I weighed at work in their labs for checking my scale. I believe the light bulb went on in the marketing department at some of these manufacturers as a new way to make money.

I have a Farankfrod Arsenal from MidwayUSA but the resolution of the tenths are in even numbers ONLY!

0.0, 0.2, 0.4, 0.6, 0.8

So understanding the limitations of the scale help to understand the +/=/- 0.1 grain. It is very accurate verified by check weights and against my RCBS 5-10 beam scale.

I like the fact I can zero the Frankford scale with the scale pan from the RCBS so I can swap back and forth for comparisons.

The digital is very nice and fast for finding unknown weights, such as with bullets or a pulled powder charge.

When it comes to mechanical scales, there isn't much that can go wrong with them except accumulations of dust and dirt. Obviously, the OP was about electronic scales and that's an entirely different matter.

Depending on the precision I'm looking for, I may use the Gem-Pro for weighing something other than powder. Then again, I may just use a triple beam, if I just need to be within .1 g.

I didn't use the Gem-Pro or the triple beam to determine I recently had 3.90 pounds of pewter, but my certified grocer's scale gave me the information I needed to figure the end result of Sn/Pb I had mixed.

I have a Pact, seems to be good. Two things with digital,
calibrate every time you use and get one you can plug in so
the voltage stays the same. I had an RCBS battery operated
and it would drift as the battery got weaker and I had to
recalibrate more often. I think the accuracy is in how you
use it. I turn mine and let it sit for a few before
calibrating. The Pact seems to be right on with my Redding
balance beam.

I have the same two scales Paul mentioned.......and that's kinda scary.    The GemPro will run on batteries or AC, which is the main reason it got added to the pile.

I have a RCBS 750, Lyman 750, electronic and a RCBS beam 5-0-5 plus a set of ck weights but I think the RCBS 750 weighs the most consistent.

Welcome to the forum! I hope you're right. The 1500 is built around that scale and that's what I use most. Come on in and sit a spell. The folks around here are real freindly and pretty smart(present company is questionable).
