How do you use the vertical divisions that the needle point to? I know some scales have level adjustment screw and adjust to point the needle to the center, but does the scale divisions mean anything? It is not described in manual and google didn't help.

HankC,
Great question!
I have an RCBS 5-10 that has marks above and below the center mark and would like to hear the answer to your question also!

They indicate weather your low or high on the target. They are actually 0.1gr graduations if I recall. I have never confirmed this, for you you want it dead on.

You can verify it by zeroing the scale, then just change the poise by .1gr and see where the pointer comes to rest.
I also have an RCBS 505, but it has no markings.

I have a 5-10 and will be glad to check for sure tomorrow... 99% sure they are 1/10 grain ...
I'm generally not happy if my powder measure doesn't throw charges that are all between the one over level and the one under level. I have never checked to see if they are actually calibrated to anything. I would assume they try for .1, and suspect they are close.
Alright, I went and did an informal test. I trickled AA #2 up to 4.0 Grs. Worked the beam a couple of times to be sure it settled back on exactly 4.0. Then I trickled more powder until the pointer was one line above level. Again, I worked the beam a couple of times to make sure it came back to exactly one line above. Then I moved the weight to the 4.1 mark on the beam. It showed slightly under 4.1 Grs. Pointer slightly below the level mark. Very close though.
Forgot to say, it's a Redding R2 scale.

On Redding scales, they're 0.1 grains. . . on many other scales they're unitless.
Read the manual.

I have the Lyman 505 scale, found the manual online, does not say anything. I pulled RCBS manual, doesn't say anything either. Did not check Redding. How is it use in practice? I always try to get to the centerline but wonder there must be some practical applications of those divisions.

I use it to tell me about how much over or under I am on powder throws.

You are correct. I believe they could be used to verify the repeatability of the scale by moving the micro poise to 1.0 grain which should move the pointer to the bottom 5th marking or weigh up to 1.0 grain which should move the pointer to the top 5th marking (this is factoring your beam scale has been cleaned/tuned to repeat zero).
On my Ohaus 10-10, I adjusted the micro drum poise for 1.0 grain and the pointer dropped to bottom 5th marking which indicates each marking is 0.2 grain. I repeated the procedure several times with the same result.
Then I moved the micro drum poise back to zero and metered 1.0 grain of W231/HP-38 on the Ohaus 10-10 until the pointer went up to top 5th mark and Gemini-20 digital scale (with .02 grain resolution) read 1.00 grain. I repeated the test several times with the same result.

Hope these old Redding instructions help.
Example.
Zero the scale. Set bullet weight with the poises. Put a bullet in the pan. The pointer will tell you how many .1grn the bullet is above or below the weight you set with the poises.

Still use my old Lyman 500 scale to set throws from the old #55 powder measure. Funny how modern technology makes people less brain active.
Maybe that's why I still like manual machinery.

They did some testing and most young children in school were unable to read time on analog clocks.
While I like the speed and convenience of digital scales, calipers and clocks, I enjoy the relaxed feeling I get from watching the beam scale pointer bob up and down, needle hands moving on the dial calipers and analog clocks that go "tic toc tic toc".
That is a good hint and practical! Thank you.

BDS I dug my 1010 out and did the test like you did and you are 100% right. I guess things are getting worse as 60 is only a few months away as I could have sworn it was a .1 grain but it is right on .2 grains.
But I do not agree with you about the tic toc of a analog clock being relaxing

Great.
I just turned 51 and wife and daughter already think I am already "there"

Ha
Ha ha I noticed things started happening at 50 and have been told just wait till 60. Well I think it already has.
That saying youth is wasted on the young is so very true these days.
Though when I was young I always thought it was just old men whining. Oops!!!!

All I can say is the older I get the longer it takes to get things done. Just don't work as fast as I use too. 4 back surgeries may have something to do about it. I did notices, 40 is when I started getting injuries from sports. Now coming up on 64 I just don't heal as quickly as I use to.
My dad use to think 60 was old, then he turned 60. Then he thought 70 was old, then he turned 70. Then he thought 80 was old, the he turned 80. Then he thought 90 was old, then he turned 90. At 90 he noticed there was very few his age anymore. (There were only 7 left in is 406 Fighting Group) His dad lived to 2 wks short of 96. Had his mind and was still walking and getting around. My dad almost made it to 93, still had his mind (sharp as a tack) and was getting round good. He was actually more mobile than me since I had all the back surgeries. So just maybe I have some of his genes for longevity.

On my Lyman D7, they seem to be just slightly over .1 gr per mark.
When I'm loading I like to keep the loaded settled so the pointer is no more than half way between zero, and the first hash mark on the low side. I try not to go heavier at all, over zero.
It can be aggravating with some powders (I'm talking to you, Unique and IMR4198) and I'm probably holding tolerances tighter than need be.
