Has anybody gone as far as measuring the weight off bb's to zsee how true theyare to the claimed weight?

What I've heard is that for example G&G 0.28g bio bbs are really 0.30g or 0.31g if I remember correct. I bought bbs which should be 0.40g but the seller said they're really 0.39g. Its close to the weight what it should be so thats fine for me.

The manufacturer will probably state somewhere on their website the deviation in weight of each bb product.

Why would it matter?

Its how they shoot that matters not the weight.

Unless you want to calculate the exact energy at a given FPS?
