Did some digging on the net, it’s a bit confusing but I think I’m ok after all.
Top pic is off the net, bottom is my scale. You can see the three poises above and just two on mine.

I’m not going to weigh charges until I can check calibration, it’s possible the beam was switched out at some point, but my guess is somewhere along the line Ohaus reconfigured the scales but not the model number on the one I have. Transition model maybe?

No word back from my Email and I’m not going to bother checking with them unless I hear back. If it weighs check weights correctly I’ll run with it.


Head scratcher for sure.

Quick scale check!

Grab several bullets of known weight.
Balance your scale as best you can, then weigh the bullets.
Using bullets isn't like using test "peas" but will give you a relative idea if you're in the ball park.

The little graduated weights used to calibrate scales are called a "pea".

Sometimes the simplest answers are hidden in plain sight.

Thanks FB, got so caught up in thinking I was stuck it didn't even occur to me. I have both 50gr and 52gr bullets for the .22-250 and some 80gr and 100gr for the .243. Several of each ought to work.

Sooo..

The "main" beam is set up in 5 grain increments and the other balance is in tenth grain increments?

game on!!!!!!!!

1F44872F-C52F-40E8-84E7-E0FCEAEACD1D.jpeg Heavy poise in 5 grain increments, light one in tenths up to five grains.

Bullet is a 52gr .224

Almost right on the money. 688F01B6-ED5C-430F-82A3-0EEDD55FC9F9.jpeg

I’d like to see how the models with 3 work.

Messed me up when I looked for instructions online, nothing labeled as a 505 scale showed one with two. Can’t even find pictures of one that way.

Must make mine more valuable😜

[FirstBubba]

Is it confusing?
If you want, say 37.5 grains, you put the big one on 35 and the little one on 2.5?
On my old 5•0•5, you put the big one on 30, the next one on 7 and the little one on .5.

I wonder?
Can you use a 5•0•5 beam on a 5•0•2 scale?

[fitch270]

You got it.

Once you’ve maxed the 5gr limit you’d just bump the big one up a notch and start over at 0 on the small side.

Simple really.


The beams look to be the same other than the poise arrangements.

I have to doubt the beam isn’t original to this 505 but who knows.

Edit: I suppose you’d get familiar with what ever you used but the less moving parts the better I’d think. If nothing else it’s one less thing to get bumped or set wrong.

[fitch270]

Just an aside, this is the box I found the scale in.

Now that I think about it I should have realized trouble lied ahead.

Why don't you call RCBS, they will probably send you the weights. Just tell them you inherited it and they are missing . Jim

The operation is, on a level, stable surface you move the 3 weights to 0 with the weigh pan on, then with the level wheel, move the wheel until the balance pointer is to zero. Then you can use it. If you move it you have to repeat procedure.

don't use it without all three weights.

Go on e-bay, there are tons of pictures of the Ohaus 505. They average about $30.
