I came across a RCBS 505, marked as manufactured by Ohaus. The fine adjust looks like a threaded assembly rather than the little slip of metal they have now. $75.

Was this model reasonably reliable, or should I be looking at something else?
 
I have the 1010, also made by Ohaus, and like Steve, wouldn't be without it. You won't regret it.

They made a 10-0-05 with a threaded unit that combined the single grains and the tenths. To the best of my knowledge, the 5-0-5 has always had three metal slides. I've had mine since 1974. I refuse to go digital.
 
I think the really old 505 might have had the micrometer style adjustment, but you have to consider wear on the pivot pins over the years. That is about the only thing that can wear out.

I dropped a 30' tape measure on my 505 and it broke the pivot pin loose from the arm (don't ask). I replaced it with a much older 1010 which has that style adjuster and like it a lot. Ohaus makes good scales.
 
I have a RCBS/Ohaus 510 that has the micrometer poise. I also have a Dillon/Ohaus that has the three metal poises. I personally find the one with the three poises easier to level and set my target weight on.
 
Been using mine since the mid 60's.

I remove the arm unit every now and then and clean the dust out of the cracks with solvent on a Q-tip, dry and put back together.........but only when the scale seems to act like it is not moving smooth and has a hitch in its get along........

Can't go wrong with an oldie but goodie...........
and the battery has yet to die on me. :D
 
There was a time long ago when it was clear that Ohaus made all the scales for RCBS and others. The fine feature you mention is a rudimentary micrometer for adjustment and they work fine. Reloading scales are a sideline for Ohaus who made a living making precision laboratory scales which one finds occasionally. Lab scales are not marked for "grains".
 
My current one is an RCBS 5-10 with Micrometer. It replaced my 1010 Lyman Ohaus that I bought in 1971. The scale fell off the beam on the 1010 after almost 40 years.

The new 5-10 is all I need in a scale. I like the micrometer Adjustment just fine by the way.

Don't know why more folks don't buy a check weight set. Cheapest insurance that your scale is weighing accurately.

It's a simple thing to check that the scale reading is the same as the check weight.

I usually take it a step further and use enough check weights to equal the charge weight I intend to throw.

Oh, I've also used my RCBS for 40 years or so without any problems.
