Touchy little bugger - I like it !!
Been sitting on my reloading bench for over a month now. Have not felt well enough to work with it till now but WOW it works. I did a bunch of research and settled on this scale based on reviews & features. Most desired was/is the 2 decimal read out. Shows me just how “dead on” I was, not, with the previous electronic scale. The plastic pan did not work out well for me so I substituted a metal pan I had. The only annoying thing is that you have to look straight down to see the reading. I reload my 223/308 from a seated position & it is bit difficult to read. Would I purchase again – you bet! Would I recommend – you bet !

There are plenty of negative reviews of this simple little scale. Trust it, it works. Old Will supplies you with a sheet to "trouble shoot" through. It shares a lot of potential interfering elements that may negatively affect this scale. I can tell you, this scale is plugged into the same surge protector as two other electronic devices. I have a fluorescent 4 - 48" bulb fixture right above my reloading bench. I have a computer server shelf, router switch, back up power unit, back up WIFI data center within four feet of this My Weigh GemPro 250 scale. FYI, my reloading room is in my back office at my place of business. I have all of these "interfering" items and my scale is consistent and dead on. I use the supplied ferrite interference suppressor and leave the scale on all the time. To date I've worked up loads for my M1A in 308 WIN and my 6.5 Grendel with this scale. I loaded to measure velocity, I loaded to confirm those velocity flat spots, I then loaded in those velocity flat spot ranges to find the most accurate load. This scale did it all. Trust it, it works. Trust the set up process and the 24 hour wait time to use it and it will work. I love being able to read grains to the 100ths. This gives me much more confidence in producing a low velocity SD.

Finally, a scale I have confidence in. I use this scale for reloading. I like the fact it runs off AC power. I generally turn it on and let it warm up for 30 minutes before use. I find the scale to be consistent in its accuracy. I like the small footprint; it doesn't take up too much room on my reloading bench. The display is bright and easily readable.

I purchased the Gem Pro250 to weigh rifle powder charges and spent an entire weekend fighting with the scale. I was experiencing all the same complaints that caused many scales to be shipped back to Old Will's. I had decided to send mine back when I tried I last thing that I have not seen mentioned in any of the reviews. I REMOVED the Anti-vibration Pad from underneath the scale. After removing the pad, placing the scale on a hard surface, leveling and calibrating, the scale has worked flawlessly. I noticed the scale would move anytime a button was depressed while it was resting on the anti-vibration pad. The pad was causing all the following problems, inaccurate weights, not holding zero, not returning to known tare weight, and drift. The pad is too thick and will compress then slowly return to normal thickness over time causing problems, Now the scale is Dead Nuts On!! I weighed a 168gn Hornady BTHP on a different scale and it weighed 168.08gn. On the Gem Pro is weighed 168.08 20 out of 20 times. I was also using it as a check weight between about every 5th powder charge. It is slow to settle when trickling powder but I believe that is the price of accuracy. I would definitely recommend this scale for accurately weighing powder. Only reason I give it a 4 is all the wasted time figuring out the anti-vibration pad was causing the problems with setup. Hope this helps!! Cheers!

Scale wouldn't keep Tare weight, called and talked to a rep who was very professional and walked me through to make sure scale wasn't working as it should. He suggested a return and they would replace, I told I would upgrade to GemPro 250 instead. I was anxious that this would turn into a Charlie Foxtrot, but the GemPro arrived and the correct credit was given to my credit card ... unbelievably smooth and much appreciated transaction.

When I started working up a loads for a new 7mm-08, I realized that it may be my most used powder measure. I use it in conjunction with an Omega electronic tricker and have found it to be quick reporting, reducing the time in this part of my reloading sessions. Let it warm up for an hour or so, it calibrates quickly and more importantly, it is accurate. I have checked it multiple times with my RCBS 10-10 balance scale (made by Ohaus) and It is dead-on accurate.

Gempro 250 - Excellent Scale for reloading
I really like this scale and the price point. Way better than a standard reloading scale... For units in grains, you get 0.02 resolution. The very minor negatives are that it does take at least 3 seconds to finally stabilize, and it would be nice if the display was a tad more upright so you can have the scale further away from yourself and still be able to read the numbers easily. I do a quick ballpark pour using a powder scoop on a cheap scale, and then use an omega powder trickler to get the charge up to the desired weight on this scale; one grain at a time if need be. Using this method cut my velocity extreme spreads for handloads by almost half. I have not found to need to use the wind blocker, but it does help protect the load cell during handling.

I was looking for a reliably accurate scale that worked fast for my air gun pellet sorting. Several reviewers had indicated the GemPro 250 was slow to yield a weight, but I wanted to try anyway. Glad I did. The stabilization circuitry does take 3.2 seconds for a final weight...too slow, but an initial weight is available at approximately .4 seconds and seldom changes 1mg from the final weight. That's plenty accurate enough for my purposes. The scale doesn't slow my work flow at all and I work about twice as fast now than with my previous two scales. The scale needs to be warmed up to get this kind of performance, but the AC adapter with ferrite loop works well...I just keep it turned on. I've gone through almost 10,000 pellets so far and I'm still very pleased.

Either stand up to weigh powder charges or put the scale at a lower level than your bench top.

First impressions. Wow it is small. Can almost fit in your hand. But in reality it is suppose to measure grains of sand with fine precision. Something so light you cannot feel it in your hand. After using it, I came to really appreciate the compact size. It comes in a very nice protective case, power supply and calibration weight. I had a small issue with it going back to zero after repeatedly placing the calibration weight and removing it. It would show -1 gram or -2 gram sometimes. This is really not a big deal for me considering the price and the fact we are talking about the difference in a speck of hair here. I simply hit the tare button to re-zero and problem solved. I would not invest in a better calibration weight. I think it would be a waste of money for this scale. The scale is pretty dang accurate for what it is. I measured repeatability accuracy using a small wire tie that weighed 204 grams. I weighed the piece about 30 times. It was very consistent within 1 gram. If you truly want 1 gram repeatability you are going to have to invest in a scale that cost 10 times what this scale cost. I would recommend this scale to anyone that wants or needs 1 gram precision. It is pretty awesome for the price.

Just like any precision scale such as those used in laboratories, you need to let it warm up to get the best results.

It settles faster, seems more stable and the numbers are exactly the same. I work out of two locations and thus will be buying another one soon. Some specifics about the unit beyond the weighing operation being good are : The pad that comes with the unit is very useful, the cover is high enough to cover my weighing pan completely without interference and makes for very stable readings. The back lit display is easy on the eyes and calibration is very simple. I teach reloading in four states and will definitely be recommending this to all my students.

I have had the GemPro-250 for a little over two weeks, and have used it to reload 500 rounds of ammo. I shoot F-Class and wanted something more accurate than my old Ohaus M5. The GemPro-250 works fines, albeit it may get off zero occasionally, but when this happens you can tell right away, and re-zero it. This has not happened frequently enough to be a problem. It helps to turn the scale on perhaps a couple of hours before starting to use it, and then just leave it on if you anticipate using it later that day. The only thing I don?t like about the scale is that it is slow. When you put a weight on it, it readily displays the weight very accurately, but when you add (trickle) a bit more, then you have to wait several seconds for the display to update, and sometimes the first displayed weight after weight is added is not the scale?s final answer as it may display a slightly different weight a few seconds later. I found that I can trickle to the desire weight faster with the Ohaus M5 than with the GemPro-250, but I hope that with further practice using the GemPro-250 will allow me to speed things up. If I had to do it over, I would buy an FX-120i from Cambridge Environmental Products for about $388 (400 CD). I would buy it from OldWillKNot, but their price is $700. A far as customer service from OldWillKnot, I can?t say yet. I received an email asking me how my recent purchase (the GemPro-250) was working out and if I had any problems. I thought this was great, and was ready to reply, but then realized that the email was just an automatic email that is not monitored so it cannot be replied, and this was a disappointment.

Calibrating the GemPro 250 with the 20 gram calibration weight (unit reads 20 grams) change the units to grains (308.64gn) and it ranges anywhere from 308.66 (0.02 grains) to 308.74 (0.10 grains) heavy. Very seldom does the unit read 308.64gn, let alone read consistently. Inconsistent calibration Trust thru Verification Every powder charge measure on the Gempro 250 is verified by a beam scale for accuracy. This is a very necessary step as to provide the most consistent powder charges I can make. I perform this process every time I use the Gempro 250. Being precise on my powder loads is a major time consuming effort, typically 2 to 2.5 hrs to measure power for 25 cases within 0.04gn of each load. This is not a very efficient method to measure powder charges. Beats the purpose of a digital scale. Note2: The beam scale is subject to not returning to zero every time due to being bumped or other unexplainable phenomenon so the use of both scales is required to verify powder charge. My shot groups have tightened since employing this methodology and my long range shooting has been more consistent. Note3: I previously bought the i201 compact scale by my weight and it is even more inconsistent and frustrating to use than the Gempro 250.

I have been using a GemPro 250 for about 4 years for reloading. It isn't a d=.0001 g scale, but they are too sensitive for most applications. I normally check the pan when I put it back on the scale, to make sure it goes back to zero. That's a pretty good indication it will read right. Trickled powder will need a little prompting from a pencil or pen on the pan to make sure it weighs what you think it should. I have an old Mettler H80 that isn't any better to use than this scale. Even with being out of a lab since 1975, things go well and two more have recently bought the same scale!

I bought this scale on the recommendation of many precision and benchrest shooting forums. The scale feels a little on the light side, but works as advertised. The included accessories leave a little to be desired. The calibration weight is 20g. A 20.0g weight would have been nice. The powder pan is a little awkward to work with due to its small size, but reloaders should have a better pan on the bench. The stage case is sized very tight for the scale and accessories. The area around the front clasp cracked for me when the power cord was caught between the top and the bottom. The scale works wonderfully, however, you need to make sure there is no air movement or drafts or any sources of excess heat or cold nearby to make sure you get a solid measurement. I use the A/C power and pug it in the night before I am ready to measure powder to make sure it is thermally stable. Since I am reloading for precision rifle, I give the scale 8-10 seconds on each measurement to make sure it has settled. I know some people will hem and haw about that, but we're loading for precision, not speed. Overall, the scale is very nice and seems to be very accurate. The .02gr precision is fantastic and easy to work with, especially with extruded stick powders and a trickler. I rate it a solid 4. If the accessories were a bit more robust and replaced the 20g weight with at least a 20.0 weight, it would be a 5. Still, I recommend the scale for its precision and functionality.

This is one excellent scale. My only gripe would have to be the pan it comes with. If you are measuring diamonds of something like it, it is fine, but when measuring gun powder like a lot of us do, it is too shallow. The powder sometimes sticks to it that it is plastic too. Other than that, it is a great scale with very little drift.

I bought the Gem Pro 250 for weighing powder loads. It worked satisfactorily, although the weight tended to drift a bit like most scales. I was pleased with it until I installed batteries. One of the positive contacts in the battery compartment was apparently installed upside down, making it impossible for one of the batteries to make good contact. No matter what I tried, the scale would not even turn on in battery-only mode. I called customer service and a replacement was promptly shipped, along with a prepaid label for shipping the old unit. Unfortunately, the new unit had exactly the same defect in the battery compartment. I could get the unit to turn on by holding the loose battery in by hand; however, it only squealed briefly and then shut down. Customer service promptly emailed a prepaid label for returning both scales. Based on my experience, I cannot recommend this Chinese-assembled scale to anyone due to quality control issues. I would give customer service five stars, but the product only three.

I've been using this scale now for about three weeks. It's easy to calibrate, easy to use, and is extremely accurate. I was using an older more expensive scale similar to this one for reloading. The older scale needed to be recalibrated constantly. The "GemPro 250" once calibrated weighs accurately load after load. I've saved a ton of time. (No pun intended.) The resolution was a key feature for me, since I also weigh other items requiring an accurate weight, down to the 100th of a gram. Seems pretty ridiculous, but I'm pretty anal when it comes to accuracy. This scale is also very affordable without spending several hundred dollars for a lab scale when this one will do. The only other item out for a verdict is it's longevity. I hope to get many years of useful service from this GemPro 250.

Great little scale when it hold "0" , but hard to hold "0" from time to time, yesterday while reloading I had to recalibrate several times during one reloading experience. The 20 gm calibration weight is either off or the scale doesn't read the weight correctly. According to my figures 20 gms. should equate to 308.65 gns. My scale continues to read 309. Maybe I'm doing something wrong. I've followed the instructions in the manual...still figuring it out.

Although not generally advertised as a reloader's scale, this item deserves top accolades as an accurate, economical and easy to use tool. I received my scale within days of ordering (thanks to Will's excellent service), and tested it out using the supplied check weight. Instructions were simple to follow. Calibration took seconds. I tried a few powder charges using a powder trickler, and the scale registered an accurate reading within .01 grains with no fluctuation. This scale will pick up vibrations and air currents, so be advised to keep it in a stable environment. It comes in a small but sturdy case and is supplied with an AC adapter. The measuring dish is perhaps too shallow for capturing powder granules (I used the dish from a beam scale and zeroed out its weight on the MyWeigh scale as instructed). One last bit of advice for measuring out powder: use caution when pouring, otherwise some granules can end up stuck beneath the scale's dish. But overall this is a fantastic addition to my reloader's equipment.

The Gempro 250 seems to be a very accurate and so far, reliable, scale. I particularly like the ability to run it off the 120 v transformer and not have the thing turning off when it times out, as most battery operated scales do. When used in conjunction with a ASTM class 4 calibration weight (which is a necessity for accurate reliable results) I am well satisfied with the results.

I did a lot of research and decide on the Gem Pro - I was not disappointed. Great product, totally accurate with repeatable accuracy - I've tried a lot of different cheap $30 - $75 ebay scales and none of them were reliable, or accurate - they each gave me a different weight every time with the same pellet. NOT with the gem pro - If I weigh a pellet I get the grain weight down to .02 of a grain - every time, time after time.

Great Reloading Scale My Weigh GemPro 250
This is a great scale at a great value. This scale makes sorting brass and bullets an easy task. I also used this scale to check the calibration on my RCBS 5-0-5 beam scale, which was off. I fine tuned my 5-0-5 and now have two great scales that consistently match each other. I did have a problem with my AC power cord making a very annoying high pitched noise. Old Will Knott Scales sent out a new AC cord right away and now everything is great. I also had drift of about 0.02 to 0.04 grains on the GemPro 250. I went to Radio Shack and bought a two pack of ferrite cores that snap over the power cord for about $3.50. This took care of the drift problem, after I give the scale a good warm up time. I don't know why the manufacture doesn't include ferrite cores on the power cord, or why Old Will does not have them as an option, as they are a cheap, effective way to reduce drift in these scales. I also bought an aluminum pan for use with powder measurements. The supplied plastic scale gets static and the powder tends to cling to the pan when you are dumping it. I am pleased with the product and Old Will Knott Scales.

GemPro 250 Great Customer Service after a defective scale
I purchased a GemPro 250 for reloading. I had used a RCBS 304, probably one of the best mechanical scales for reloading that was ever made. But, time took its toll and I could no longer rely on the scales accuracy. Trust me, when I say I look hard and long for an electronic replacement. I decided to buy from Old Will Knott Scales because I couldn't find any derogatory reviews about this company. When I received the scale I was more than pleased. It seemed to perform as I'd hoped for, but I soon noticed that it wouldn't calibrate correctly. What drove me nuts was when I removed some propellent from the dish, the weigh would go up instead of down. I called Old Will Knott customer service, and like they say, you actually talk to real people who are concerned. After our conversation I tried it again for a day and called them up again and they sent me a no cost return prepaid label for UPS. I was just informed that my scale wouldn't calibrate for them and a new scale is on the way. As we all know, as important as the product is, the company you buy it from is as important, and maybe even more important. I was informed that these scales are rarely defective and coming from a company like Old Will Knott Scales, why should I think otherwise. I load 45 ACP, and I look forward to getting that replacement. The GemPro 250 reads out to hundreds of a grain. Most of the electronic reloading scales read out to the tenth of a grain. I don't know about you, but one tenth of a grain is a lot of propellant, so it seemed like a natural to go to this scale. I use a Hornady Progressive Lock-N-Load press and my case activated powder drop is amazingly accurate. Before the scale became unreliable, the powder drop was routinely dropping right on or two hundreds of a grain either way of what I was loading. How's that for accuracy? I was using Hodgdon Clay, which is more difficult to load than a ball propellant. The GemPro 250 is a good way to go, and Old Will Knott Scales was certain the other good decision I made. Happy shooting!

It makes sense that the most accurate scale would be designed for jewelers, who have the most to lose from error in weigh measurement of jewels and precious metals.
