Me and Biggin just bought 20 buckets of weights. They were level full, leaving enough room to snap a top on them. The clip-on weights went from 130# to 160# and the stick-on weights were a little lighter at between 110 and 120#. These were weighed on a scale and those weights included the buckets. The lighter weight of the stick-on weights were a surprise, but probably should not have been. They just did not settle in the bucket like the clip-on's did. Many of them were twisted and curled up and used more space.
