My Ohaus 10-10 is over forty years old and was the first bit of serious loading gear I bought after high-school. Ohaus is a brand mostly associated with weighing gear used in actual scientific laboratories , so they have fairly high standards.

Serious money, then and now, but, in all those years and after probably hundreds of thousand of rounds, the ONLY thing that has been replaced is the dinky anodized alloy pan. The handle snapped off about six years ago, so I bought a new one. All I had to do was adjust the amount of lead shot ballast in the pan carrier so that it would zero correctly, (with the "calibration" / "booster" weight supplied at purchase).

It comes out for EVERY new load development, EVERY change of propellant batch, EVERY bullet and case grading session and EVERY bulk reloading session.

The plastic cover is a bit murky, the paint on the chassis is shabby, but, apart from the pan handle breaking off, it has NEVER let me down. They remain the only set of loading scales I have ever bought.
