2. (b) the fact that the weight is so ascertained or accepted is stated in the bill of lading, then, notwithstanding anything contained in the applicable rules, the bill of lading shall not be deemed to be prima facie evidence against the carrier of the receipt of goods of the weight so inserted in the bill of lading, and the accuracy thereof at the time of shipment shall not be deemed to have been guaranteed by the shipper.
