I got a small scale, the Bing pellet I got from eBay is 46.5g so nearly double the weight that it is supposed to be... I believe Nick's earlier post of a smaller Bing pellet of 25g is correct.
For reference, the Wilesco cylindrical weight is 25.8g.
I do remember someone posting a squarish weight for a Bing, so I am considering trimming the bulky one I have...
