fun with scales and new weight kit

[castalott]

I have 4 powder scales and a new Lyman weight check kit.

177909


I thought it might be fun to check these against each other. I bought the scales all used and the RCBS was throw in the bottom of a large box of stuff. I don't know if it is damaged or needs TLC..it was the only one that 'stuck' anytime.

I did my best and these are honest measurements. And you can 'interpret' numbers such as 4.95.

A few notes:

The RCBS looks like it was literally thrown in a box and stuff thrown on top of it. It acts it too.

The CH I have had since 1981. Very good scale but slow with out damping....

I expect the 'dial a grain' needs cleaned and checked. It was the funnest and easiest to use.

The Ohaus 505 would be a very nice scale if you had to choose one...

I suppose all of these are 'inferior' to an electronic scale.... But there isn't much to go wrong with them or batteries to replace...

You can interpret the data.....

Hhmm... The data didn't post like I typed it....

Don`t compare apples to oranges like magnetic/manual scales to electronic scales. I have a Dillion and a Hornady dispenser scale and 4 manual/magnetic style scales. Both electronic scales were farther off the target weight than any of the 4 scales, 2 of which are Redding #1 oil dampened scales. At present my most near on the money is an older Lyman D-7.Robert

Scale check weights are an eye opener, aren't they?

After verifying a scales accuracy, I tend to use them by matching the selected powder charge and making sure the scale pointer goes to zero.

Thank You, Sir! You are a scholar and a gentleman... there aren't many of us left....

After verifying a scales accuracy, I tend to use them by matching the selected powder charge and making sure the scale pointer goes to zero.

That's how I use check weights as well. I start by zeroing the scale at zero. Then, I pick the powder charge then use checkweights to zero the scale at that weight, or as near as you can get to it with your checkweight set. Routinely, there's little or no difference with little or no scale adjustment necessary.

I have a RCBS 505 from 1978. It's still spot on. That thing really amazes me!

I have an RCBS 1010 that I wouldn't trade for anything. It is dead on accurate and easy to use. I bought it early 2000, and forgot about it til last year. It added a new level of enjoyment to crafting excellent rounds. For the plinking stuff, still use a progressive. I must be getting old, been enjoying doing it the "OLD WAY" from the 80's.

Wow! Me too! I've enjoyed loading on a single stage again... I have progressives but it seems more like work than pleasure...

My old 'Pacific' Scale...is just a Balance Beam with a pointeron the end, and an index reference the pointed end lines up with.

I have to establish a given weight in the hanging Basket and adust the weights on the Balance Beam for that...then, adjust my Powder Dispenser to throw "that" Weight, checking the charge in the hanging Basket, to make sure the Pointer is right dead even with the index mark.

The Balance Beam is threaded and has two little weights which adjust by turning them along the threaded shank of the Beam.

Seems very reliable...takes a while to settle down on it's own, so I usually dampen the bobbing with my fingers.

Strictly a Powder Scale, not for weighing Boolits.


It came with a little gaggle of reference Weights, and using those I made a few more to give me a little more variety.

That's certainly going back to basics :). I have a couple of these in my collection of old scales, they are excellent tools, there's just nothing to go wrong as long as the knife edges are in reasonable condition.

There's no question of reading the wrong weight - if it balances it's the same as the last load and the one before that. I have a slightly later version with oil damping, if you weigh your preferred weight on a cheap digital scale and dump it in the pan, then just adjust the locking nuts to balance point, every load will be the same.

My Powder Dispenser is an older "Ideal No. 5", and so once I have adjusted it to throw a given charge based on the Scale Reference Weight(s), I just dispense right in to the Cartridge case...and I double check a Case's charge every tenth one or so, testing it with the Scale just to make sure things have stayed the same, and so far, they always have.

I've gotten pretty good at 'dampening' the Scale via the side of a finger tip barely rubbing along the side of the suspended Pan...but the Scale can sure rock a while if one does not do that.

A man with a watch always knows what time it is. A man with two is never sure.

Years ago, I passed a shiny new dime around to all my buds to weigh on their scales and got similar results:

1 Dillon electronic: 34.4 grains
1 Dillon beam: 34.6 grains
2 RCBS beams: 34.7 and 34.5 grains
1 PACT electronic: 34.5 grains
1 Lyman beam: 34.5 grains
