A friend of mine asked me the other day to recommend an electronic scale to him. He still uses a balance beam scale and wanted a scale he could read a little easier. It looks like every manufacture of E scales limits their warranty period to 12 months. That's not much of a warranty for a $100 piece of reloading equipment, IMHO. I have an RCBS Electronic scale(made by Ohaus, I think) that is over 10 yrs old but I have heard that later ones have a tendency to **** out after a while. I couldn't recommend a brand of scale to him but I told him that I knew a very large group of reloaders who could chime in and give him a heads up. Any suggestions?

Any more getting more than a years warranty on electronics is almost impossible today. About all you can do is what your doing and ask from others. Also look at the units and the internet likes and dislikes. I had a small hornady digital that wandered and lost zero often.
I have a Dillon but its a very early one that worked good for many years. A Rcbs that also is going on 10 years old and is accurate. A Gem Pro 250 that's 4-5 years old now and accurate and nice. It has .02 reading also. I still use a beam scales for a lot of things but the digitals can be use full. Its a little different trickling charges into a digital scales than a beam type though. It takes some change for the load scales to detect it every time, once it reads a small change may not be seen or take a longer time to register.
I would recommend the gem pro 250 ( 250 grn capacity and .02 grain reading) for powder. For checking my bullets its not enough capacity normally. It was around $125.00 when I bought mine. If you want to check the bigger bullets there is the Gem Pro 500 ( 500grn capacity and .1 grn reading) Sinclairs have some very good ones also.

The power switch on my old neva scales stopped working. I bought them cheap off fleabay a good 10 years ago, so i decided to buy a new set, after trying to develop a new load i found out the resolution was .2gr, so my powder was off every few throws till i worked out the reason.

Ensure you look up the specs to make sure they go .1gr or better. There is cheap, and there is cheap that isn't usable for reloading.

I have since repaired the old scales by installing a good used switch, i should have done that first hey?......

I trust my old RCBS 5~10 beam scale because it always agrees with my old style RCBS 2 piece auto powder dispenser, it's digital and can be quickly calibrated...like I said, those two scales will agree down to the tenth.

I bought a portable digital scale from Midway a few years back, it too can be calibrated with a little weight that comes with the scale but it never agrees with the other two...I quit using it.

So...the problem as far as I can see it is this; if you change to a new digital scale you purchased and are loading hot, near max or max loads that you have developed off an accurate beam scale...how can you trust the new digital? You can't until you see if it agrees with your beam scale.
I wouldn't buy one, switch to it and continue to load without checking the new one out thoroughly. Also, if you read the instructions carefully, do the instructions ask you to give the digital scale any warm-up time?
If you check the specifications of the new digital scale, does it say to use it in an area where the ambient temperature is bracketed? That may have something to do with accuracy too, some of you Northern BrassStuffers work in some pretty cold shops.

I have had the F.A. DS750 now for maybe about 6 months. Before that & still have & use an RCBS beam scale that I have had for over 30 years. The FS scale is ok for a lot of loading I do since it is quite fast & easy, but if I am approaching any Max load specs, I go to the beam scale.

The only trouble I have found is that it seems to like to "remember" weights I have "thrown" & trickled on it. I do not really know how to explain it. I will try though if ya want to read the long version below..

Short Version - It works just fine for me if I am not concerned about .1 gr.+/- in my loads, even though it is said to be calibrated to .1gr. I would say it has caused me enough concern that if I was approaching a Max load specification I would not use it unless I stayed at .2gr below Max. & then if it is off I will not be over Max.

If someone is not pushing Max. loads & is not concerned with being +/- over .1 gr. and are ok with up to .2 gr. differences from what they are weighing, then it should work fine. I would buy another, but if it did the same as what i describe in the long version below I would complain to F.A. & look for another elect. scale or go back to using the beam scale.

YMMV of course, & maybe mine is the only one or one of the few out there that has this quirk I explain below.

G'Luck to what ever ya decide to do.
:)

.-------------------------------
Long version -

For example of the "remembering" .... When I am working up loads for testing like I have been lately for reduced loads for the missus. I go up .1 grain at a time, not .2gr.. I have found that by doing this I can get loads dialed in better. ( To each their own/YMMV) I have found specific differences in load changes even that small & "to me" that makes a difference. Particularly with some fine low load powders such as Red Dot getting down to 2.2 gr. using 38sp. just for one example.

Anyway, since I am doing this & loading up by the .1 gr. I will set my powder measure at the bottom amount & then trickle in up the loads from there til I am done. Usually 10 per load amount. Now, I started out just weighing the loads of powder alone, then transferring by funnel to the case. But, I found it faster to just tare the case itself, then add powder to it with the measure separately, then set on scale & then trickle up to the next load weight. To check that I was not having scale issues, every so often, maybe every 5-10 cases, I would take the load that was trickled up , dump it into little pan after the pan was tared & then see if the charge changed. This was part of the verification for safety & making sure the scale was true.

Once in a while though, the scale , when I was trickling, would not seem to register the amount i was trickling in & then jump to the next number after a long time of trickling. It seemed to want to stay at the number it "remembered" more than change up to where I was trying to reach. [ For example, If I was trying to reach 2.7 gr. with the measure st to 2.5 & I had just done the 10 2.6 loads, when I went to trickle up to 2.7 on the next series, it would like to stay at 2.6 for what I thought was too much power for a .1 gr.. So I would verify by putting the powder in the tared pan to see. Sometimes it would show that I had passed & went to 2.8. So I would dump the load back in to the measure & do it over.]

This "remembering" did not happen often enough for me to not use the scale any longer, but as particular as I am in this process, it means enough to me to pass it on to those who wish to use one. Mine may be an isolated situation, but even if it is , I found it & can deal with it. If I get uncomfortable with it, I can always go back to using the beam scale. Even though it is a bit slower, IMO.

[ Note: I have checked it to the beam scale & it is right on & I should also mention & i calibrate every time I turn it on.]

That is the long version.... The recommendation is the same from me as above.

"If someone is not pushing Max. loads & is not concerned with being +/- over .1 gr. from what they are weighing and are ok with up to .2 gr. differences, then it should work fine. I would buy another, but if it did the same as what i describe in the long version I would complain to F.A. & look for another elect. scale or go back to using the beam scale.

Yeah, sometimes JB my RCBS digital with sit there and 'mull' when I think it should be responding, so...instead of trickling over too far, I'll simply touch the scale and cause it to do it's job immediately. I keep telling it..."You ain't gettin paid to think, just weigh!"

I'm not sure it pays any attention to me either . . . :bigsmyl2:

This is pretty much the message I gave my friend. Always and I mean always check your E-scale against a beam scale of known accuracy. He has an old Lyman beam scale but his eyes are like mine and the lines are not as sharp as they used to be. As Pres. Reagan said, "trust but verify". I think he likes Lyman stuff but for warranty I would suggest RCBS. We will see what he decides.

This is the scale I use, supplemented with a larger dish/funnel. FortuneCookie45LC's review was complimentary although it was overkill in sensitivity. It measures grains to the hundredth of a grain...where as the others (Hornady, RCBS, etc.) measured to the tenth of a grain. It is important to note that ALL scales have some operational inaccuracies, such as hysteresis, etc., but when you can measure to one additional significant digit, it HAS to be more accurate.

In the past I have purchased several inexpensive digital scales and have been very disappointed. Recently I purchased a Frankford Arsenal Platnium series scale, and I am pleased with it's performance. One of the biggest problems with digital scales is they can give you a false sense of security. We tend to believe the digital readout without question. The problem is they need to be checked frequently to ensure accuracy. The less expensive scales tend to drift without warning. If you have a digital scale you need to buy a weight check set and frequently check your scale. I still use my balance beam scale when measuring max loads.

My scale is the one that came with the older RCBS Powder Pro set and it has the 110 v transformer that plugs into the scale with stepped down voltage and it has performed flawlessly for 10 yrs. However, like most electronic things, it has been discontinued for something else (read cheaper made). I wonder how the battery scales respond to the battery voltage going down as the loose their oomph.

If you want to buy a scale that's made in the US w/ as many US made parts as possible then you want a PACT. http://www.pact.com

I have two electronic scales that I trust. One is a RCBS Chargemaster. The other is a PACT DPPS. I've had a lot, and I mean a lot, of other digital scales and they all failed in some way. One I will recommend that I haven't used is the Gem Pro 250. There have been enough good reviews that it's proved it's worth for reloading purposes.

They all have voltage regulating circuits built in, the electronics work off much less voltage and current than you might think.
They have a wide window as far as the battery and power supply is concerned but...when the voltage falls below that window/parameter, things will go askew if not shut down all together until it's replaced.

The scale might have a battery warning symbol that comes on, when it does...replace it and your good to go. But...the problem I've had is having the battery puke inside of the instrument and ruin the battery contacts...even quality batteries will puke, I'll be glad when we get to the free energy technology that's hidden from the masses...no more batteries!

No kidding! I had a name brand battery puke in my game camera and it took a ton of contact cleaner and a lot of brushing to get it out. The camera gave up the ghost shortly there after. Are we ever going to get batteries and electronics back to this country where somebody is proud to build quality products??

I have had a Dillon D-terminator for at least 15 years, prob more like 20.

Has been reliable the whole time.
I don't like checking the calib of a scale I weigh 5-50 grains on with a 25 gram check weight.

One gram is 15.4 grains, so my check weight is 385 grains.
Your calib check should at least be close to the measurements you expect, if not bracketing the expected measurement.

I run a chem lab, have access to 0.0000g grade scales.

I made 5,10,15 and 20 grain check weights out of paperclips.

Other than that issue, love the Dillon.

Well, well. I just got an answer to my email question from PACT. They said that their scales are made in Dallas, Tx. right down the street from their office. If you have to pay a few $ more, it would be well worth it to get an American made product. At least you could understand the person on the phone. That's something a lot of customer service calls don't offer!

update: I just went to the PACT web page and their electronic reloading scale was listed for $129.95 and it has an IR port. It is a dead ringer for my RCBS scale that has been a treasure for at least 10 yrs.

How is that scale going to equate out to the average handloader? What is the base price on that commercial certified scale?

Long ago I worked packaging powders and we were using electronic scales that would read 0.1 gram which is nowhere near the sensitivity you are talking about and still those scales would barely last 1 year when used 8hrs. a day 5 days a week as a weigh check.

My go to for weighing charges is a Scott Parker tuned Redding. It is amazing but time consuming. Especially if I'm just tuning a powder drop for shotgun or pistol on the progressive.

So I use a Jennings JSR-100 ( IIRC ). Fast and seems to be precise enough for what I need it to do. You can find them for $20.

I had a Lyman 1000 XP Electronic Powder Scale I used for years. Paid $200 for it. It worked OK but eventually the materials used on the buttons degraded to the point where the buttons failed e.g. stuck. No amount of cleaning changed that. The scale also quit working dependably. It always had problems drifting, all electronic scales drift to some degree, just the nature of the design of these scales that use load cells. Th Lyman scale drifting got worse with age to the point where it was useless and I threw it out and went back to using my RCBS beam scale. I have a Frankford Arsenal cheapo pocket digital scale I bought when they first came out, and I use that scale today to validate the setup of my beam scale (old eyes). The cheap digital works well enough for that, and weighing boolits. I'd love to have a DEPENDABLE electronic scale that doesn't drift once it's calibrated. IMHO that's a unicorn. - Skook

I have used several electronic scale's and all drifted, so now I use a RCBS 505 with check weights for powder charges and use the electronic scale's for bullets and brass.

To help my old eyes I put a 2"x 3" 5 power magnifier in front of the 505 pointer so it is easier to see.

Beam scales are not immune to reading incorrectly. It's true that gravity doesn't lie. But if the poise is bent or if the scale isn't level it won't read correctly. Both types have to be confirmed w/ check weights. Otherwise you have no clue if they're reading correctly.

Over the years, for one reason or another, I have bought several B.B. scales. Which include RCBS, Lyman, Redding, Ohaus and Texan. My old cast iron base Texan is my goto BB scale. I can alway rely on it to be accurate. Also have bought a few electronic scales, usually off brand like Franford that proved to not work from the getgo. Despite all of this, I still crave to own a decent electronic scale. Today I bought a RCBS Rangemaster 750 in nice shape off the internet for $45 shipped. It was missing all of the add on parts like the AC power cord, 20 and 30g calibration weights, platin and powder pour cup. I called RCBS to order the missing parts and they ended up shipping them to me for free. I can print out an instruction sheet online. This is not the first time that RCBS has treated me like this. Their customer service is second to none! I suspect they will keep my new toy going one way or another. /Chris

I have two Hornady electronic scales about 3 years old. The original GS-1500 and the LNL bench scale. Both read the same as my Ohaus 10-10 and RCBS 505. I don't use the GS-1500 much but leave the LNL bench scale plugged in all the time. All my loads are handgun and are from 2.5 to 30 grains. When loading at the top of the load data I will check it to one of the beam scales and have never had an off reading yet.

It seems like most consumer grade electronic scales promise accuracy +/- one tenth grains. I've used a $20 Franklin Arsenal that works fine. Spent more money on a "nicer" one (closer to $100)...guess what...same results as the cheaper one.

I have a cheap mtm case guard and it wanders not much maybe 1/10 of a grain up or down .so will not trust it its the only one I ever used so maybe that's normal don't know. Have a Lyman 505 and a Lee scale . I always go back to the Lee just easiest to use. Use other to to check the Lee but it always checks accurate. And as I say muse easiest for me to use ( personal preference).

country gent brings a good point which is "what you weighing?" Match 45-70's pills will up to 600 grains. 30-06 brass 135 to 180 grain range. I bought an RCBS in the '90's to do these jobs. I DO NOT shoot red line pressure loads in anything save 222 Rem. I do all my powder work ( setting throwers-checking) on a RCBS beam scale. Electronics will drift as they warm up-cool down-==>PITA check often until you get a feel for it.

I have the AWS scale and have had to have it replaced twice ( completely went dead ) and the customer service was good but it took 2 to 3 months to get the replacement.

My scale drifts a lot and constantly has to be re zeroed, so I rely on my RCBS 505 scale for small powder charges and use the AWS for brass and bullets.

Is the Chargemaster faster than the 1st gen auto charger? Mine is so slow that I don't use the power measure any more. I just throw a charge a gr lighter than I want, then trickle the final amount. The first gen (Powder Master) unit is very accurate though.

Murf, I don't know if its faster but it will dump a 308 size powder charge faster than I can put the case in the press, seat the bullet and remove the case from the press. I mean its faster than I am. And mine very seldom drifts.

murf205

11-27-2017, 11:25 PM

That's a lot faster than my old Powder Master. When you hit the dispense button on mine, you have time to make a sandwich,LOL. I was using an old Lyman 55 measure and bought an RCBS measure with both rotors, and life got a lot easier. When you get the "feel" of the powder measure and duplicate it every time, the RCBS throws amazingly close charges. I check pistol charges every 10 rounds and if it is off by more than 2/10, I dump them and fill the hopper back to where it started from. I don't use very much fast burning powders and I don't load max loads, so 2/10 is my cutoff. The accuracy of the Chargemaster is a distinct plus. My friend loves easy, so I will pass along what you said about the Chargemaster. Thanks

Those Power Powder measures are way above my pay grade. Will stick with my beam scale.

Last scale you will need. Most people won't spend the money.
If you are loading a lot of weighed charges for match shooting, weekly/monthly, it is a must.
It is a joy to use.

I have two PACT scales, one is 20+ yrs old(pre IR) I use to sort boolits and cases. The other one is much newer and part of the auto dispenser system. I do check every tenth charge on a balance scale, I haven't had any significant drift. For max loads or serious long range stuff I'll dispense slightly light and trickle up on a balance scale.
Some of the previous posts there were complaints about the speed of first gen. RCBS Chargemasters, there was a parameter update. I think it can be found on the PACT web site
