Unfortunately my powder scale is a Lee, made to weigh powder, not completed rounds with 200+grain bullets in them.
Used to be able to get Ohaus lab balances on eBay for $50 or less. Haven't looked in a long time but probably still the case.
I picked up a old green single pan (old, older than me in fact) and a modern beige double pan that way.
The double pan is in mint shape, and I never used it. I'd sell it for $40 if anybody had a use for it.
It would be great for comparing loaded rounds, just zero it and put a round on the right pan and compare other rounds by putting them on the left pan.
