Opinions please, Scales

22-250 Varmint Rifle
Rifle: Rem. 700, Dave Kiff Bolt, Krieger 27 1/4”, Shielen Trigger
Scale: RCBS Rangemaster 750 ($100.00, is 5yrs. old) weigh each load.
Weather Condition: 70 degrees, Wind Calm, Sunny, 5 p.m.
This Target was shot at 100 yrds.
Center target, zero scope (Leupold 6.5x 20x)
Left Target dot 32.5grs. Right target dot 32.7grs.
These are five shot groups. I find .2gr. does not make a lot of difference to this rifle. Again, this is my varmint gun.

P.S. The attached file has had to be downgraded significantly and if you really want to see it without the downsizing just let me know.

I guess at some point

I have the acculab 123 and it faithfully replicates the weight. When I weigh powder, I dump into a glass vial which fits into the opening (hole) in the plastic cover. It is less vulnerable to air currents with that setup. When I load in my motorhome I have to wait for any movement caused by wife or dog to resettle. These scales that are accurate to 1.5 hundredth of a grain are verrrry sensitive, but once you get used to them, you can be sure that any mistakes downrange aren't because of powder weight fluctuations. I love mine. Randy J.

we musta reached a consencus on this "Weighing Thing", EH?

Looks good. Does it drift much.

This scale located on loading bench, no protective cover. As I load,I will
rezero scale ever 8 to 10 loading. This scale has no drift that I have notice.
I am very satisfied with scale.

I would guess NO

How about a good old rcbs 10-10 scale. Are these as accurate as the 123's? Lee

BUT i don't know for sure. If you have one simply weigh something of a known weight repeatedly and record the reading each time. That will give you a good indication
 
No, a 10-10 is not as accurate as a 123. One more thing, have you noticed how little movement a tenth of a grain causes on the pointer of a 10-10? Set it to be exactly zeroed, weighing something, and then change the setting by .1 and let it stabilize. Read it looking level, preferably with magnification, and then without, more casually. Even if it repeated perfectly, which it doesn't, reading it to the tenth is tricky and subjective...not a good thing. Does this matter, for most applications, probably not, for the most critical....apparently.
 
Well, Tech at Ohaus finally called today and said my Navigator scale is NOT repairable. They're just going to send it back. It may still have some functionality so I can get some of my moneys worth out of it.

centerfire, any more word on the HCB 123 battery situation?
 
New battery arrived

Well I received a new 6 volt SLA battery for the scale and all is well.
I charged it up over night and the scale works fine. I use the technique of hitting the tare button, scale settles, and then I put the pan on the scale, tap the pan and then cover the unit. All seems to be going well.
This Adams scale has a lot of extras and even has a weight for zeroing the scale located inside the scale, or you can use an external weight.
I think it is a keeper.

Glad to hear all that. I'd order one today except my wife and daughter are dragging me and my son-in-law to Las Vegas next week. I'll order one when I get back. I'm not a gambler so I'm not worried about having money left to buy the scale. :D I'll probably spend more money on buffets than slot machines. Haven't had any experience with these electronic slot machines. Last time I played was the spinning wheel ones. I think thats more entertaining than what they have now.
 
It is total foolishness to trust the calibration weight that comes with a scale. Test weights come in various degress of accuracy. There are at least 4. The best ones will cost as much or more than the cost of the scale and should never be touched with bare fingers. Just the oil on your fingers will change the weight.

Well I finally got to test the Adam HCB123 scale and take cartridges to the range Sunday.
I preloaded at home from my Harrell to the Dillon scale and then to the Adam.
The Adam confirmed the weight to the .x place with the Dillon but allowed me to adjust the .0x amount by adding or removing powder as needed.
On this short test @ 38 degrees I had a SD of 6 on my Chrony.

The major thing I did was to turn off the internal calibration and turn on the external calibration using the 50g weight that came with my Dillon scale.
By doing so the weights between these two scales was checked to the .xx place.

Minimum drift and hitting the tare before each weigh solves this problem.
Hope this helps you with your decision. :)

OK Donald...... we're weighing rifle powder here. Just what do you suggest the INFORMED shooter in an attempt to avoid foolishness do? This pertickler fool is perfectly happy NOT to buy a scale weight that "costs more than my scale" and instead just to bumble along with that hideous variance hiding in the system. My thought is that as long as the scale is reading to within the weight of human oil on the scale..... it's close enough!

for ME

My wife is dragging me to las vegas tomorrow so I don't want to order until I get back. Who did you order the scale from? So far the best price I've found is at affordablescales.com.

al,
Just making an observation is all. I guess it makes no difference at all as long as it repeats. Just pick up a little rock and use that, as long as the scale repeats and stays stable. A bit like the man with two watches, he never knows the exact time. :)

:p


And I've got 5 "watches" a drawer full of weights (some of them in liddle boxes ;) ) but don't feel the need for an iridium cube in a vacuum chamber. :eek:

And I still refer to "weight" in "pounds." :D

LOL

You know, there's a use for those ends of boxes of projectiles you used years back when you plinked with a .222. Those 50-55 grain soft points can be desnouted & bored out to make "standard" weights for all those loads you use regularly. It's not to difficult to scratch the weight on the jacket with that scribe you likely have lying around & for me at least, it makes me real comfortable that I'm shooting my chosen load every time.
 
Scales and calibration weights.

A little knowledge regarding quality scales that approach "lab grade" and appropriate weights for calibration never hurt anyone. Some good reference information is available here..... http://calibration.balances.com/sartorius/calibration%2Bweights.html#class

For the range of scales used to measure gun powder something in the range of ANSI/ASTM Class 2 or 3 is in order.

Quality weights for calibration or reference are often available on an unmentionable auction site at very reasonable prices. $20 delivered for an individual class 2 weight would be a good investment for particular reloaders. Even if you are just weighing gun powder! A 10 gram check weight comes in at 154.3235 grains plus or minus the class precision. 10 grams happens to equal 50 carats used in weighing diamonds and is often used to calibrate scales used for weighing diamonds.

If you buy something to use for calibration be sure you match up with the size required by your scales' calibration procedure.

I bought my scale from affordablescales.com I paid more for the Adam HCB123 with the battery backup but they have a model without the battery for less money if your interested.
Remember "RED" when you get to Vegas. Might win a scale! Oh Boy! :)
