M2 Calibration Weight - 20 Grams
Terrible. Grossly inaccurate being very much underweight. I purchased this weight as a extra for my portable range reloading box scale. Upon receipt I immediately checked the Cal. Weight on my my reliable scales. 20 grams equals 308.647 grains. This Cal. Weight equaled 304.1 grains. It was four and a half (4.5) grains underweight! This is totally unacceptable. How this product got out of the factory is a mystery to me. Obviously I returned it for a refund.

We know you have a choice when you buy scales online. Just know that when you buy digital scales from Old Will, it's always a "Worry Free Deal".
