I imagine it would be quite an difficult test because sure they would have to test with the heaviest commercially available pellet and ensure that it didn't go over with that, thus ensuring it was under powered with everything else. Nightmare!
Not sure what the tolerance would need to be Ray, feels like a mine field.
