Digital Scale

Gentlemen, check out a website for canadianweigh. I just purchased the "JsR50" total 21 and change cdn. Comes with a 20yr warranty and is accurate with .01grain. Pocket sized, runs on aaa batteries and is meant for reloading. You can put the powder pan on the scale and then it will weigh the powder only. It fits in a shirt pocket and isn't very thick. When I get it next week I will post more about it, but right now I am pumped to receive it and try it out.

is that the JSR 50 - 50g x 0.01g ?
if yes, then it's a 0.15gr scale (most likely 0.2gr)

I bought this one a year or so back and it's proven to be truly amazing. First off it's got larger numbers than many other options so it's "old guy eyes" friendly. Second is that it remembers the last units used so I don't need to trip through to set it to grains every time like some others. And finally it holds zero well over a good length of time. Again this is something that some others just don't manage to do. It's by far the nicest cheap digital I've used out of four others that have turned out to be a PITA or just gone dark.

In fact I think I'm going to order another as a spare due to liking the one I've got so much.

Being that this particular seller is in Hong Kong it means that Canada Post will deliver it right to your door or mailbox. So no nasty surprises with US sellers using FedEx or UPS.

Ordered! At that price its worth a shot.
 
All this talk about digital scales got me looking on KIJIJI. I found a used GEMPRO 250 for $55 shipped. I already have an RCBS 502 and a 10-10 but I want to see if this will make my life easier.

Resolution for that scale is 0.1 gram=1.5 grains, don't you think that's too coarse of measurement. For example it'll read 30 grains but only update when weight is 31.5 grains?
In my opinion absolute minimum resolution for a reloading scale should be 0.1 grain = 0.006479891 grams(round up to 0.01 gram)
 
I bought the Gem Pro 250 from Quarky Science , Victoria BC for $236 all in delivered to my door. It weighs to 0.02 of a grain, I can get my wieghts dead on but it is slow, weighing to +/- 0.02 gr is much faster and is 10X more accurate than my RCBS 10-10 scale and 100X more than the powder measure. I'll see if my ES drops .

When measuring in grains, what units does it read in? (ie .1 gr?) How repeatable is it?

The one I gave the link for resolves to 0.1 grain. It seems very repeatable from what I've seen.

unfortunately the battery powered ones turn off automatically.

Yes, they do. But again after having about 5 different battery operated scales for my other hobbies and early loading use this one has a longer auto time out period than most. I can easily cycle the ram 3 times into a casing to get a good average measure without the scale timing out and turning off. This particular one also stays on more than long enough to use it for dumping then trickling up to weight for rifle charges.

These reasons are why I'm so happy with this particular scale and why I posted about it. Early on I had one which worked well and much like this one. Then it died and I went through TWO other cheapies which drifted, turned off too soon or reset to grams when turned off. I've still got them but I'll likely chuck them during the next cleanup because they are just frustrating to use.

As for warm up drifting I've only had that with one of the scales I've got. And again the one I linked to up above does not have this problem.

Ebay also has some more serious 30gm scales that resolve down to .001gm. Translating this to grains we're looking at a max weight of 460 grains and a resolution of .01 or .02gns. But be warned that at this sort of sensitivity you can't have fans running around the weigh station. Air currents will affect the last digit. Even breathing on the scale also affects it. For the $30 it cost I got one and it too seems to be pretty good for not drifting over time. The plan is to use it for any super serious rifle loading. I won't trickle the loads to the last .01gn but it would be nice to know that when I'm aiming at .1gn that it really is at the .1 and not up to .05gn low or high.
 
Just a heads up, the RCBS Rangemaster 750 is $104.99US at both Midway and Amazon dot com
With shipping to the border and tax, Midway ends up $1 cheaper
CAD is $0.80USD as of this post

edit: there's also a $10US rebate from RCBS to be cashed
 
Cheap scales do not necessarily drift, well not all of them. Had the jsr50 and have weighed hundreds of items with no issues of drifting. Perhaps the one in the video is the lemon of the bunch......
 
Got my ebay scale today.

The good: Nice compact size. Good hefty weight. Scale settles down quickly. Nice sized display with bright backlight.

The bad: As Ian pointed out, the resolution of 0.01gram isn't great for reloading work.

If I'm reading the scale properly, if you reload to full grain values, it'll work but you'll have that 0.9grain variance before the scale changes over to the next full value ie your powder weight could be 4.0gn or 4.9gn and it'll show as 4gn on the display.

Folks would want to buy a scale with a higher accuracy level like 0.001g resolution?

0.001gram is going to be expensive
0.005gram is more affordable yet still goes for $140 in Canada and it's not guaranteed to be a good reloading scale.
I'd rather get a designed-for-reloading digital scale that consistently measures +/- 0.1grains
