What scale are you using these days?

Well I am now eating my words as I ordered a Gempro 250 yesterday......lol

Found one for $155 US with free shipping so I will give it a try. I will try and borrow a friends Vic 123 and see if I can do a side x side comparison of the 2.

The 123 replacement mentioned earlier was in the $270US range which was the cheapest I could find online.

Have had a few PM's asking where I found the scale.
You can find it HERE

Jerry,

If I were to upgrade my scale today, which one would you suggest??

MACK20 is the least expensive start into better digi scales. I used one for a few years and it was certainly better then any scale from reloading companies.

The Gempro is what I am using now. It is quirky and fussy but once set up and you learn how to use it, very fast and consistent.

It drifts (at least my unit) and that happens in a minute so you just need to keep an eye on your tare value and reset as needed. this means that if you weigh something and just leave it on the scale, over time, the value WILL change. The zero value is changing so the "weight" output changes in relative terms.

As my goal is speed, not watching powder sit in a dish, I have a routine which gets my powder weighted and into the case pretty quick. By being consistent in how the scale is used, the RELATIVE weights are very precise and repeatable.

Perfect, not in your life but given the cost of competitive products AND their own limitations, I am happy with how this scale is working.

Being +/- a kernel or two of Varget isn't going to make my loose sleep or miss a V bull.

That is close enough for what I want in a scale. At least for now....

YMMV.

A best friend had one of these 15$ Chinese scales you speak of. I thought it looked like a terrible way to measure powder and NO way it could be 0.02gr accurate. Well...... I was a tad bit embarrassed when we did a side by side comparison with my 7000$ scale at my work's lab. By no means was it 0.02 gr accurate more like 0.05gr accurate. The 15$ Chinese scale tracked side by side through 5grain to 100 grain calibration weights I had. Anyways got me thinking...

I too was skeptical when I ordered it, and blown away when I used it.

I don't know if the one I have is .02gr accurate or .05gr accurate, but it is most definitely .02gr consistent. The load cell is sensitive enough to know the difference between a large kernel of Varget and a small kernel of Varget. Too bad the display resolution is only .02gr.

I have two of these $15 scales and I can transfer 24.50gr Varget from one to the other and get a reading of 24.50gr! Good enough for me.

Yep, and adding a reducer and changing those settings will make the CM incredibly accurate.

Some just add a McDonald's straw, but I found it to be useless alone. I initially just rolled a piece of paper around a 3/16" rod and insert it. I used it like that for years before machining a proper reducer. The tube restricts the flow of the powder so that you don't get a big clump of powder putting it over your weight. I've found that different diameter holes work better for different powders.

I only adjusted these software parameters:

HSP_A1 to 8.00
HSP_B1 to 3.00
HSP_C1 to 1.00

Its slower, but it doesn't overflow at all. You can see a single kernel put it on the desired weight each time. I calibrate my two Charemasters with the same set of check-weights so that they read the same and I have some precision check weighs to verify periodically that they are keeping their readings. A simple check is to just verify that the readout is -(pan weight) when you remove the pan to dump it.

Also watch for static buildup between the housing and the plastic platform. It causes most errors and drifts. I wear and anti-static wrist strap that is grounded out. This dissipates static each time I pick up the pan. I rarely get drifting now.
 
I run the hornady auto charge, works great. I have my beam scale beside it as I don't know if I can trust the hornady yet, but every charge it spits out weighs what its supposed to when I double check it on my beam scale so I'm happy with that.
