The absolute accuracy over the full range of capacity of the scale is not important. What matters is the differential accuracy of the scale at one setpoint, because when you are reloading a set of cartridges, the object is to to make all the cases contain the same weight of powder. You are focusing on the wrong measure of accuracy.
Heres my thoughts. the RCBS is a budget scale. If you want accuracy, go buy a force restoration device. A thousand dollars should be enough. Now as far as reloading goes, you have 2 options. If you are hunting and just using loads from a reloading manual, the scale is probably close enough. However, if you are intending to reload for accuracy, you simply work up the loads, using your scale and adjust accordingly. Ie if the best/ accurate load measures 45.3 on your scale, and it does that consitantly, then you are fine. The reloading manuals only provide a guide and are written for average brass dimensions. So start low and work up your loads, keeping a record of what your scale measures. Or spend a grand on a really acurate lab scale.
I too have just started reloading and have the same setup you have, and the same problem. I can weigh a 55 grain hornady v-max and it is dead on, however when I weigh two at 110 grain it is about .3 heavier than it should be.
@@perrseb5772 no it was not the scale. The scale works pretty darn good, here is the video of it working with the new rcbs calibration weights. ruclips.net/video/rAqDkayRKB4/видео.html

kev paul Bullets are not always exactly the published weights. The Hornady s, I’ve seen them vary quite a bit. Don’t gauge a scale without an accurate set of check weights.
I would check the quality of your cal. weights. Those don't look like quality weights. Purchase a set of grain weights for reloading. Lee makes a nice set. You can also have your weights checked by someone that has an accurate lab scale.
Put all weights sliders to 0 Use the screw on the left end to zero Get say 150 grain bullet set weight sliders to 150 it will read 0 It set. Use bullet to set. It will read dead on. Just slow as hell.
Hi, did you solve the problem? It may be the weights also. If it could have the, check with a calibrated scale or simply with another set pf weight to see if you have the same bias.
Sorry for some reason RUclips is stopped notifying me of new comments. Anyway the scale measures and grains but the old test weight said I had was in grams therefore I converted grams to grains to do the test. after this didn't work too well I went ahead and bought a new set of test weights and grains from rCBS
Why would you get check weights in grams instead of grains? Lyman make a great set!!! I think the problem is these check weights are for digital scale. Send them back get you money back and purchases a set of grain weights. Remember I would not trust weights from a no name outfit but that is just my two cents!!
us.ohaus.com/en-US/products-13 As it turns out ohaus is quite the scale company. And I'm having trouble finding a set of calibration weights in grains. I found that RCBS has them and Lyman, I guess I will order some.
Randy's DIY looks like some super high quality scales for sure!! When I first started reloading I tried to hard to make my powder so perfect that it got to be a headache then after reading more I forgot to put into account the these scale have a Plus or minus variance so if you are off by .03 or so you are not going to see the difference on paper the main thing to focus on is consistent measurements repeatable that’s we’re you are going to really benefit from reloading your own ammo and that is were true accuracy will show!! May I suggest a great reloading manual the Lyman 50th reloading manual is a great book. Lee makes a great manual too!! They give you way more bullet and powder combos to have in your reloading experience plus they have loads for cast bullets that is going to save you money in the long run! I could go on and on I hope this helped!!
Thanks for the info, I have the Lyman 50th, the Lee manual and the Sierra looking to get the Hornady next. I guess I'm just a little crazy I wanted it to show the exact weight when I put it in there but I understand what you're saying as long as it's repeatable That's really what matters.
Randy's DIY well if you are looking for a Hornady book they offer a app that will give you there 10th info and next fall they will send you the 11th hard book for just $19.99
Get some proper grain-denomination cal weights. They are widely available and RCBS is just being cheap by including gram weights with a grain scale. Shame on RCBS.

Thanks great advice
What happened from this? My rcbs scale is dead nuts accurate.
I made another video. It turned out to be the calibration weights I were using were not a good quality weight set
@@randysdiy2102 thanks. I wish I had check weights earlier. They are so reassuring.
Didnt see you go back and check zero during process?
I too have just started reloading and have the same setup you have, and the same problem. I can weigh a 55 grain hornady v-max and it is dead on, however when I weigh two at 110 grain it is about .3 heavier than it should be.
Thanks for the input, I have ordered a new set of rcbs calibration weights. I will post when checked.
Randy's DIY hi there, was it the scale? I am about to order this scale...

Yeah I had a link to the newer video in that old video that shows where I purchased a set of RCBS calibration weights and the scale was almost perfect
Put all weights sliders to 0

Here is the revised video
Nice, problem solved! I work in a lab, and first thing first, having a certified quality weight is essential. Have a nice reloading!
Is the scale measuring in grains or grams

Hmm, Looks like Your Zero is off by at Least that much?
I'll have to check maybe it's parallax from the cameras point of view. I'm going to watch the video though to see if I see what you're seeing. Thanks
Use grain check weights. Otherwise you are just guessing.
If you check out one of my other videos, I bought a set of RCBS check weights and the scale was almost perfect

You should never touch test weights with your bare fingers. Moisture from your hands weigh.
Tweezers!
Problem solved! Video coming soon. RCBS Scales are GREAT!

Yes sir, my follow-up video shows the scale working properly with the rcbs weights
