they are accurate to .02 grains. I figure if these wander , they will never wander enough to alter charges by .1 grain. best scales spec wise for the price. only time will tell. so far I sat one grain one the scale 6 hours ago and it still read one grain dead nuts every time I check it. so far, so good.

also lifetime warranty with a quick turn around out of Arizona , also made in the USA, I think these are gonna be great.
I'm also investing in an old school beam / dampened type grain scale for verification purposes etc. soon.

How much that run you if you mind me asking.

Get a set of check weights, more accurate then a beam scale.

You can't use one unchecked scale to check another scale. A good beam scale is a nice backup but you need cert check wts.
FWIW, any drift is bad because you often can't predict exactly how much it is drifting. I submit 0.02gr accuracy isn't very important, but NEVER drifting is.
I have one of these and am pleased that I invested in it. Also have two sets of check weights.

I believe I paid around $110 iirc. May have been on sale

So we are still at over $100 for a good elec scale.;)
I saw mine was inspected by "insert Chinese calligraphy # 670" as well for accuracy etc. maybe I had the made in USA part in my mind BC they are lifetime warranty and you send them back to AZ????? I swear I read it "Made in the USA" the description and that was a selling point to me.
And still no wandering and the scales seem to be wha I had hoped for, so far . I am super gentle with them and they came with a rubber cushion for preventing vibrations and such and also a ferrite choke adapter to block electronic interference from the AC power source I believe, new to me????
I purchased from a licensed retailer, Old Wilkes on the net to insure I could utilize the lifetime warranty, therefore I probably didn't get the best deal but got a few extra goodies, the extra mat and choke. I think I saw them on eBay for around 125$. I paid 144$ on sale free shipping. these will be stationary for years to come as long as they don't require being sent through the mail for repair.
if they screw up I will be the first to say something about it on the forum !!!

these also came with a 20 gram check weight. I know I need multiple throughout the spectrum of weights. max is 50 grams on these. which weights should I own.
thanks for the info. I just found the lyman 210.5 grain total package for 40$ free shipping on eBay. good looking out.
just noticed your link is cheaper lol. thanks again

The weights provided are for zeroing the scale, like after you move it. They are really useless in determining accuracy, too heavy. Something under 10-20grains, not grams. It doesn't have to be cert check wts, IF you can have something weighed on a cert scale. Then just use that.
The Lyman check weights are good enough. Like Fred says, use smaller weights to determine accuracy for the things we weigh. If you do mostly pistol stuff then under 10grns, if you are only doing rifle, then 20grns should do to give you confidence in the desired weight range. Truthfully, if you had an old paperclip that was checked on a certified scale, you could use that if you kept it and a note on what it actually weighed in an old "ring box" or other closing top small box and never touched it except to check your scale.

As a reminder... any check weight should never be touched with your fingers. Use a tweezers or wear a surgical glove to keep skin oil and acid off the weight.
Thanks guys, Great info. I load from 9mm to .308 so my spectrum varies from 5 grains to 50.
I will just go ahead and purchase a decent cheap set that fits my spectrum of use. I enjoy acquiring tools and etc for reloading. lyman or rcbs one, whatever I find cheaper when I buy will be what I get. Thanks again.
and today they are going back, under full warranty of course, All of a Sudden zero is non existent. I'm jumping from 1 - 25 grains sporadically. something went wild. there was small lightning storm , everything else is fine in the house on that circuit. Who knows?? Glad they have a sweet warranty. $144 and problems isn't sitting to well right now though. my 43$ mtm set came to the rescue while these are down.
I tried re calibrating linear and with just the 20 gram weight.
It still reads my check weights correctly, but then starts going APE very shortly after. Odd.

Really Excellent scales up to this point. what a few months LOL!!! Can't figure what all of a sudden happened??? Gonna give them one more try.
I can tell you what happened - they are electronic and even the slightest interference or disturbance in your circuitry can make them flakey. Sure, you can't see it in your lamps or your computer, but it's there.

Fortunately, I know a simple fix:



Get it tuned and there's almost no substitute.

yeah I feel a set of those coming on soon. should've done that the first time. Good news is I have a brand new 144$ set of scales on the way that I'm considering selling to fund a balance set.
One question, I like / have to weigh every charge, how long do those take to settle after dumping a charge into the tray? that's really been my main drawback, imagining a scale teetering back and forth every charge? hopefully, I've exaggerated the time in my mind?

I just don't trust a powder hopper to drop the same every time once I've got it set. Typically , mine does pretty well in consistency, .1-.3 grains , and it's the standard Lee red hopper. I know bc I've weighed every single charge dropped LOL, still for me to feel confident I need to verify the weight of every charge .
if you're looking for consistency with a beam scale, I think one of the best methods is to throw a low charge then use a powder trickler to meet your charge weight.
It's truly amazing that I'm able to make such great ammo, usig my $20 F.A. scale for verifying charges!!
