Scales

[Buck69]

I'm looking for a scale that is accurate and with a resolution of .01 gr. Tried a Dillon and it would drift after 3 or 4 cycles!

 

[Fishersjohn48]

Are you looking for digital or the in my opinion superior beam type scale?

 

[Buck69]

Is there a beam that will give a consistent +/- .1 grain?

 

[Fishersjohn48]

I use/trust/recommend the RCBS 1010 Resolves to .1 grain easily.
The RCBS 505 is also another to consider and may be a better choice for normal reloading where heavier weights are not frequently weighed. It is also more economical.

Thanks. I would prefer digital if I can find one that's accurate and don't drift. I'm currently using my son's medical scale accurate to .001 grams. I'm going to have to give it back shortly.

I use the Dillon beam scale as a backup but primarily use a RCBS Chargemaster digital scale and never had any trouble with getting .001 resolution with it. I constantly check it against the Dillon beam and it always checks out good. You can buy just the RCBS scale separately or with the powder dispenser combo.

Bear in mind that digital scales are more sensitive to temperature change than beam scales. They really don't like it to be cold and take a while to warm up. I reload in my garage so the temperature changes pretty drastically. Therefore I find the beam scale preferable.

.01 grain ----- ONE HUNDRETH OF A GRAIN !?! That is One 700,000ths of a lb. Just over 1/2 milligram.

For reloading, I think +/- one tenth is as tight as you would ever need. An RCBS 505 will definately get you good readings for +/- one tenth of a grain, even a 502 will. The trick is, at that level even your breath will offset the balance, so you have to protect it from air movement. A simple box over the back, sides, and top will greatly isolate air currents and make it less frustrating to read.

I have worked on a balance that could easily do 1/2 a milligram. It was in a standards lab. It had its own limestone foundation that was 10 feet into the ground seperated from the buildings foundation and floor by an elastomer ring at least a foot thick and had a cabinet around the system where oxygen was evacuated and the sample hung in purified instrument nitrogen. Probably outside of most peoples reloading budget.

Would be hard to explain to the wife...

Yeah, but think of the miniscule velocity spreads you'd achieve!

 

[Buck69]

Thanks for all the input.

 

[Buck69]

I've worked on equipment and built a clean room for emissions labs, so I'm aware of the scales you describe. The medical scale I use has a top, back, front, and doors on both sides. It's pretty stable and I reload in a conditioned room in the house.

Buck69,

I use a Veritas s123 balance. It has a mass resolution of 0.015 gr (1 mg). That is about the best you can do without getting into the analytical balances.

what kind of money do you want to spend

 

[45Guy]

I use the RCBS Charge Master 1500 and check it against other scales. It has been 99% on the money and when it is not it alerts you that it has a issue, which is then very to reset.

Here's what I've been using and pretty happy with it so far. It seems very consistant and sets up quickly and easily.
Pro 500 Scale from Lyman

A Precision Beam Scale at an Affordable Price Pro 500 Scales offers precision accuracy on a high impact styrene base. Features extra large leveling wheel, dual agate bearings and large dampener. Zeros in seconds. Accurate to 1/10 grain. 500 grain capacity. WEIGHT: 1 lb

Something else to consider:

Leave your electronic balances ON. And don't move them. Make danged sure they're level - and, if you can, isolated from the rest of your reloading bench. Pulling those action levers on presses can certainly give an electronic balance some bad juju.

Look into the possibility of getting an anti-static device to keep near your balance, too.

+1 on the great info, for sure.....

 

[Buck69]

Thanks everyone, a lot to consider.

I use the chargemaster too, but there are times when it acts up on me and I'm not always sure why. Most of the time it works great though.
