I bought an R.C,B.S. " 5-0-5" Scale about 35 years ago, along with a set of scale check weights. Have since used it constantly, both for weighing rifle loads and for checking pistol & shotgun loads. I'd say it was a good scale !
If I were doing it again, I think I'd look at the R.C.B.S. "10-10" Scale. It has the identical type of balance beam with grain and 1/10 grain adjustments as my old 5-0-5.
Tried one of the newer electronic scales ( buddys') ... didn't like so didn't buy. Prefer my "oldy" .
