+1Luddite here, I don't trust e-scales, I can't see if there is a problem and can't fix them.
They do and that is a problem finding shell holders today. There is one collet type aftermarket available but never did care for it.Those herters presses were beasts, and took a different shell holder than what is standard today iirc.
I do something similar.
Boy I miss Herter's catalogs! I've got some Herter dies around and still have some Herter bullet' My Press is a Rock Chucker, scale is an RCBE 505, powder measure is RCBS and case trimmer RCBS. I don't know that RCBS is the holy grail of reloading tools but they have worked well for me over the years. I have RCBS dies, Lee dies, Hornady dies Redding dies, Herter dies and seems something else. have a Mec 600 Jr 28ga press and a Ponsness-Warren 16ga press and had a Texan FW years ago that I wish I still had! Used a Lee loader quite a while and the loads went bang and didn't blow up a gun. Started reloading with the Lee loader hand tool! Was called the Lee load all I think. Those lee and the Texan FW were to only press's I ever bought new!
So does the entire drill slide back and forth?
