Just wondering what feelings are on Digital scales and measurment accuracy ? I have a set of old RCBS 505's that seem to vary slightly between loads , ok for varmint rounds but would like to get a set of Digital Scales possibly something like Gempro 250 for a bit more consistency between loads .
Dont particularly want to spend a small fortune on acquiring a set. I'am open to recomendations and opinions.
Cheers ,

For what it's worth.
I inspected the knife edge seats on my Redding Model #2 through a microscope.
They were terrible!
I folded a piece of 2000 grit Wet and Dry over the sharp edge of a snap-off knife blade, and ran it carefully accross both seats. (I had to remove the little end plates first)
The result was a smooth seat, with a slightly rounded bottom.
The scales will now show movement with just one granule dropping into the pan.
As far as Digital Scales go, there is no guarantee the shown value is the actual value, but ditto beam scales. It is repeatability that we want.
I've tried two expensive digital scales, and the problems I found were that "return to zero" was NOT good, and, that a small addition to the powder pool, didn't show up as well as I would have liked.
IF the beam scales are clean, well made and in good order, my humble opinion is that they are superior to ditital scales, unless you want to spend a few grand on Lab types, and climate regulate the room.
Of course, as is alway the case, there are blokes out there who use digital scales and shoot the heck out of me with them!
