In B bay there is a bucket full of shot with tape over the top hanging from a cable. The mechanics are to put a tensiometer on this to check before use. Nothing is sealed that insures there is the posted weight. It's just a guess that it is what is says. If they want a true test, would it be safer to get a calibrated cable to check on? Who knows if shot has been added or removed from this bucket.
