Probably not as well as you think. I shoot skeet years ago with a guy that was on the Army rifle team, one day while chatting we got into the reloading aspect of it. They use a Dillon 550 with some custom bits added and an RCBS powder measure for their “training” rounds, but use a manual scale for the competition stuff, I asked why not a digital. Come to find out AC powered scale are all over the place due to the nature of AC current, they couldn’t get consistent drops and even had an electrical engineer design and have built something the “cleaned” the current before it got to the scale…still wasn’t clean enough. No idea if he was pulling my leg or not (I think not), but on the surface some of it makes sense…I know my own scale fluctuates.
