GemPro 300 Digital Scale – A poor choice for reloaders



A quick look at the MyWeigh GemPro 300 Digital Scale. This scale might be great for other users, but I can’t recommend it for reloading use. The GemPro 250 is a better choice in this price range.

    have you had or heard of problems with the gempro 250 reading err0? that's what mine is stuck on out of the box and haven't been able to get ahold of anyone with myweight

  • GAAkuma - January 13, 2018 reply

    Take off the screw in your gempro 250 and clean out the inside of it, it gets debris in it and throws it off. You can fix it, give it a try

  • Dima Prok - January 13, 2018 reply

    Johnny, I seriously don't know what you been smoking on Aug 19th, but I timed it in your video and it takes 1 SECOND to stabilize for your GemPro 300, I timed MY GemPro 250 and it takes 3.75 seconds to stabilize! Same thing happens on 250 if I speed trickle, when I stop the numbers will keep going, I am surprised you never noticed that with your 250. The main thing that bugs me about 300 is that it seems less accurate. But the bigger numbers and tilted display is what 250 sorely lacking, it took me a while to get used to it after RCBS scale.

    MyWeigh has a wicked warranty for the 250, I sent mine in and they sent me a new one! great service

  • Ivo Biancucci - January 13, 2018 reply

    I have the Gen Pro 250 was good until it goes wacky exactly like yours did – now using a Hornady digital scale which seemed good going to check Amazon

  • TATV Canada - January 13, 2018 reply

    What an eye-opener; to think that a precision $100+ scale would be beaten out by some $20 Amazon… Wow. I've used a cheap MTM Caseguard scale for over a decade and always wondered if the more expensive units were worth it. Glad I saved my money.

  • Joe Ragman - January 13, 2018 reply

    The tare weight works the same as zero. It just subtracts the weight of your powder pan so you don't have to do the math when you put the powder charge in the pan.

  • Big_A - January 13, 2018 reply

    What about version 2 of the WAOAW scale ?

  • Black Bear - January 13, 2018 reply

    I Don't feel confident using digital scales. I have a Lee powder measure, but don't like using that either. I now confidently use my Lee beam scale. I use a Lee dipper and top it up with a trickler… works for me anyway… another great video mate. Keep them coming. Cheers.

    My RCBS Chargemaster lite works great so far no over or under charges

  • ricky lahey - January 13, 2018 reply

    I wont use an electronic scale. I had a hornady electronic and depending where you placed the pan on the scale it read a different weight. I dont have time to make sure i am placing everything exactly the same every time. Went back to my old old rcbs beam and doesnt matter where the powder lands in the pan, it will read the exact same every time. With the electronic i was getting over .1-.5 grains difference with .5" movement of the pan. May not be a big deal to some, but to me a half a grain working at near a max load is a big deal.

  • my1956effie - January 13, 2018 reply

    A little hzrsh on z cheapish scale but a good review. I have the gen6, constantly weighs .1g low

  • treesablowin - January 13, 2018 reply

    Nice job

  • Jeff Greer - January 13, 2018 reply

    I just wanted to let you know because I don't know if anyone else has ever told you this, but your one of the best reloading channels on YouTube. Even if you don't post a video everyday. Thanks for all the great videos.

  • more clay - January 13, 2018 reply

    Frankford has a scale that looks a lot like the whammy 🤔 or whatever it's called. But is ac/dc Amazon sells it for $70 been waiting for you, Elvis or F. C. to do a review on utube; reviews on Amazon are good. Ooo… you can use ur Frankford trickler cuz it's thinner like the whammy.
    Thanks for all info you share ⚠️

  • Big Racer - January 13, 2018 reply

    No electronic scales for me, don't trust them. Beam scale only. Good vid.

  • Long Ridge - January 13, 2018 reply

    Thank you for clarifying that blowing your face off is bad.

  • Garry Oldham - January 13, 2018 reply

    I had that Lyman and without failure every single drop was 2 tenths of a grain off, usually under but every now and again over. I returned it and got the RCBS chargemaster and it drops perfect every time. It is a little bit more money but imho worth it.

  • Shane Rhodes - January 13, 2018 reply

    I'm kit sure about the Lyman powder dispenser but my Hornady is very good I get some over throws with it until I get the slow time figured out to each powder but it has been a great item for me so far I really wanted the Lyman but my wallet just didn't let me spend that much money lol but that's next when this thing goes to hell but let me know how the Lyman works out for you

  • LIVIN CINCY - January 13, 2018 reply

    I am glad I went with a Beam Scale.
    A powder dispenser would be nice for load development. But I would only use it for that purpose and not when I was loading.

  • navionflyer - January 13, 2018 reply

    Zeroing your scale and then adding the powder pan and hitting the tare button is technically the correct way of doing it, but in practical terms, the way you are doing it works just fine. I've wondered why some manufacturers do it that way, but I'm guessing that it appeals to a certain segment of reloaders.

    tare: a deduction from the gross weight of a substance and its container made in allowance for the weight of the container; also : the weight of the container.

  • mojo jojo - January 13, 2018 reply

    The best scale I have ever used is my decades old Lyman/Ohaus M5 beam scale. That thing is so precise and is consistent. I don't use digital scales anymore. I know there are very good ones but the last couple I had were a pain in the butt and always drifted all over the place. I won't use anything other than my Ohuas beam scale

  • josephhomen - January 13, 2018 reply

    Ok ok I'm going to Amazon and buying the $20 scale! I hate my old $175 Lyman scale.

  • Jeffrey Burnette - January 13, 2018 reply

    I don't see a problem with it. It's just not fast enough for You. And thats ok. Looks like a good buy to me.

  • T Hutch - January 13, 2018 reply

    Thanks for the review JRB. It seems many people own a Gem pro as it's the entry level option for weighing to 1/100th. Reviews on the gem pro products are all over the map, some people love them and many people have had nothing but problems with there scales.

    I find myself trickling into a older American made acurized Ohaus beam scale when not using the RCBS charge master. There is a gentlemen named Scott Parker (I think he's on accurate shooters forum) who will Accurize your beam scale for you and also sells them already finished. He will only work on the older American made scales or Redding scales for current manufacturers. When finished they will be repeatable and weigh a single grain of Varget.

    Looking forward to your results on the Lyman as I have a RCBS charge master that I also use that works well with no complaints.

    Thumbs up JRB, keep up the fantastic vids.

  • Joseph Villabroza - January 13, 2018 reply

    did you change the batteries on the 250 i heard you gotta change them even if you have it plugged in

  • shoot2survive - January 13, 2018 reply

    Can't wait for your review of the Lyman gen6. I own one & love it but it's the only electronic scale I've ever owned so nothing to compare it to. I do use my gem pro 250 to double check when loading my 6.5 creedmoor for precision. I see rcbs came out with the chargemaster lite, that would probably be a good one.

  • Bill Smith - January 13, 2018 reply

    Your Wonderwoman comment turned me into a new Patron. Looking forward to the gen 6.

  • Aaron Anderson - January 13, 2018 reply

    Time to bite the bullet and get the RCBS Chargemaster!

  • Steven Kolp - January 13, 2018 reply

    Thanks for your daily videos. When you stopped for a few weeks, days, earlier I was going through withdraw. I'm also glad to see who those hands belong to from earlier videos. LOL!

  • Nick J - January 13, 2018 reply

    So is it the WAOAW the one you like, not sure !

  • NYC Reloader - January 13, 2018 reply

    Hey Johnny great scale video I have had my eye on the gem pro scale you are reviewing and the reviews on Amazon were all over the place. After watching a recent video by Elvis Ammo I went with the Waoaw scale. I have four or five scales now and I know how each of them has different issues. Glad to see your feedback on this one and I can't wait until you review the other scale. Not sure I would ever buy a powder thrower scale but I await your future comments. As always thanks for this video and keep them coming.

  • Thor's Axe777 - January 13, 2018 reply

    Johnny. Good video and thanks for the advice.

  • minutemanqvs - January 13, 2018 reply

    I have the Lyman and it's nice, but it often throws 0.1 gn less than expected. The Gen5 did the opposite and did often throw 0.1 gn over. Now the Lyman also sometimes doesn't measure "fast enough" and throws too much powder because it didn't register the change of weight it just added 0.5 seconds ago…I guess no scale is perfect.

  • Neil Harris - January 13, 2018 reply

    I think you will really enjoy the automatic powder dispenser. I generally use mine for throwing loads once i have a load developed, but use the gempro 250 for load development to remove possible slight variations in powder charge as a concern.

  • 452Rob - January 13, 2018 reply

    Looking forward to the Lyman video. I've been wanting an automatic powder despenser for years and kept putting it off. Midsouth Shooters Supply just had their mega Hornady sale so I snagged the Hornady at a pretty substantial discount and I love it. Makes working up loads and loading extruded rifle powders less tedious.

  • Jeff Wessinger - January 13, 2018 reply

    Thanks for all the great info and the daily videos rock!! Let us know how the customer service and warranty turn out!! Also, just noticed that when you follow the link to the Waoaw scale there is now a version 2! Have you heard or seen anything about that one?

  • Eric Polley - January 13, 2018 reply

    Gee Johnny, if you don't like that Gempro, send that sucker to me!!! Haha!!

  • Michael Lavazza - January 13, 2018 reply

    My 250 just went bananas…..lasted 18 months. Pretty sad about it really. For the $ I was expecting it to last longer.

  • tsd12miles - January 13, 2018 reply

    "2017 reloading fidget spinner" LOL!

  • Burnoutman721 - January 13, 2018 reply

    I got my gempro 250 after your first video when you recommended it, and I love it! Let us know how their customer service treats you. Hope they replace it for you. I don't want September to come what are we going to do without our daily videos?

  • Jeff Simon - January 13, 2018 reply

    My Lyman 1500 scale is just about the same as far as the quickness. I don't find that to be a problem personally, if I'm loading that precisely it's for maximum accuracy loads and I go slow anyways. For range ammo loading, I just measure every 10th round to make sure the powder throws are consistent (which they normally are),
