Anyone know this scale?

[ar10]

It looks like an older style Lyman M5 beam scale. Information on the directions/maintenance booklet state Ohaus Lyman M5 Precision Loading Scale.
It's a single beam scale in a small metal case and can weigh over 1000 grains with the 500gr weight in the kit. It also says it a "magnetic damper" using magnetic field on non-magnetic copper.
My question is how accurate is this model of Lyman distributed scales.

Excellent scale. Almost, if not, identical to the RCBS 10/10.

Ohaus is a scale maker. That is what they do. They have made many scales, for many different companies. That should be great scale. I would use it.

OK, then my next question, (and I don't have a clue), is what kind of cartridge holds 1050 grns of powder
I pretty much know what regular "human" brass cartridges hold. I'm just guessing but the only thing I can think of is some type of monster elephant gun or maybe a shotgun on steroids

You may not necessarly need to wgt out 1000gr powder charges, but you might want to wgt heavy cast bullets, shotgun slugs, or arrows. Scales are used for weighting more then one item.

As for a cartridge that holds 1050 gr of powder............according to the A-Square manual the 105MM uses up to 210 oz of propellent. A bit more then 1050 grs

1050grs?

Wow, the 700 NE uses 2 grains of Bullseye to ignite 255gr of VV 165. Still a bit short of the 1050 mark.....

(BTW, that is pushing a 1000gr bullet to 2442fps........:banghead

I don't think that tiny cup can hold that much at one time, but I'm willing to try it if I could get a 105MM case.
Does anyone know which die I need for my Hornady LnL.

There are scales with various capacities on the market. And, some capcacities might just be based up the design of the scale with no real intent for reloading.

"...how accurate is this model of Lyman distributed scales."

The Ohaus M-5 and 1010 scales were and are excellant. Accuracy is unsurpassed for any reloader's needs.

If your's is complete it will have a small brass weight in the cup of the leveling screw. Hang it on the left end of the beam to achieve weights above 505 gr.. It is marked for it's weight so you can check accuracy with it. Mine is 260.9 gr., if I remember right.

The top weight attainable is not 1,050 gr, it's 1,005 gr. On the newer 1010 models, it's 1,010 gr.

Prior to the advent of electronics The Ohaus brand was the best of the small scales used everywhere for everything even postal scales . I remember seeing their scales as being for arrows, and pharmacuticals . The name was seen on many small mechanical precision weight instruments. Powder scales were just an offshoot of machines that came before.

You're correct it's 1005 gr. I did check it with my Lyman electronic scale and it matched. I think what I like most is the dampening and the total weight of the scale. The Hornady beam scale moves all over the place when adjust to 0 and when I check my powder loads it never really stop rocking. This one does neither.
Unfortunately I can't do a damn thing with reloading right now. I figured out I have way too much "crap" laying around my shop didn't want to blow myself up. I'm in the middle of building two very heavy duty cabinets for all my reloading stuff. I decided to use a bunch of left over plastic laminate to line the cabinets but all of it is in pieces it's taking some time.

A little off my original topic but I think I should mention it. Those "less expensive" particle board, pre-fabed cabinets just aren't heavy duty enough to hold much reloading stuff (brass for one). And before you decide to put in cabinets, wait a few months until AFTER you start reloading.
