Is this your digital scale? MAXUS Dante Milligram Scale 50g (click on blue box below)

Amazon.com: MAXUS Dante Milligram Scale 50g x 0.001g Includes 20g Calibration Weight, Scoop, Powder Pan and Tweezers Read in Grain Gram High Precision Reloading Jewelry Medicine Powder Digital Gram Scales: Industrial & Scientific

$22 cost and .02gr resolution/readability.............really!!?!!

Lemme know how that thing truly performs.

After reading your original post and assuming that you are loading for pistol cartridges, I'll say YOU ARE GOOD TO GO! Quit worrying about things this minute.

I never fully trust a Digital Scale & Verify on My RCBS Balance Beam Scale that has never once lied to Me in 35 years

I am genuinely curious as the comments and reviews with regards to these type scales measuring to +/- .02gr also state that occasionally the scale's zero (tare) will drift as much as a couple of tenths of a grain.....which is exactly the same problem I have with my digital scales that measure in 1/10th grain.

This is the scale. I do want to re-emphasis, this is because of my bifocals and unsteady hands (Too many years as a heavy equipment tech). I STILL will be verifying on the balance. I am impressed with this little cheap digital, though.

The scale will work fine, regardless of the brand they are all made in China. Best ting to get is some check weights to verify either scale is correct. Amazon has them as well.

If you powder measure won’t co-operate with your chosen powder, then adjust the powder measure to throw light by two tenths then trickle up to exact weight while the pan is on a scale.

Then, if you don't mind, please repeat the process with just a 5gr powder weight.

I am truly curious as to how repeatable such a scale is...............and if it is truly repeatable then what brand is it and what would one cost?

1 grain = 1/7000th of a pound.

You scale is measuring to a degree of 1/700000th of of a pound. Wow, if it is truly repeatable..........and somewhat affordable.

Usually I have to rely on a beam scale to show very minor deviations (above or below) 1/10th a grain accuracy. I've tried several "affordable" digital scales in the past but always went back to a beam for finer accuracy. Maybe things are changing with regards to digital scales?

Thanks in advance,

TennTx32, I didn't forget. I got it done today. Getting a 40 gr and 5gr sample required putting a cover over the scale. Breathing even affected the reading.

On the 40 gr test, it averaged 40.025 with top at 40.06 and bottom at 40.00.

The 5.00 test averaged 4.96 with high 5.00 and low 4.95. I was in the process of doing a second sample when I tipped my pan and had to start over. Second test averaged 5.00 with high at 5.03 and low at 4.97.

Photos attached. Pardon the foot and bullet holes 😆

Thanks for the update Jw.

Did the zero/tare ever wander requiring you to rezero the scale during the process?

No, the zero never changed. That's consistent with what I have observed every time I use it. This holds true whether it is zeroed with nothing on it or zeroed with something on it brass, a tray, etc.

I guess with the pandemic, it is ok to waste time on scale accuracy. The thing I'd like to point out to new reloaders or those considering reloading is that these sort of things aren't necessary, unless your scale is unreliable in the first place, which rarely happens with name brand equipment and if one follows the manufacturer's recommendations. Powder measures which throw + or - .1 grain are good to go. For pistol loading, the most important factor is the condition of the base of the bullet. Bullseye pistol competitors are the most discerning group of pistol shooters and these parameters will, with an accurate gun, produce 10 shot groups at 50 yards which measure 3" and under. Getting sidetracked with minutia doesn't produce better groups, it just wastes time that could better be spent on reloading more ammo or working on improving individual skill with the gun.

Nobody is wasting time or getting sidetracked with minutia. We are simply discussing how reliable and repeatable his digital scale is since it measures down to 1/100th a grain......and is very inexpensive.

I was genuinely interested.

Thanks to the OP for the additional info provided.

I completely understand what you are saying and it is a good point for future readers of this thread. I'm picking the fly Sh** out of the pepper, but that's what I do. I am good with .1gr deviation. But it is nice to know there are affordable digital options.
