Expanding bar shot
A number of examples of expanding bar shot were found on the site, however, in most cases these were fragmentary.
Two examples show the construction details and sizes BA T 8479 and BA T 8480. BA T 8479 consists of two circular disks (31 mm thick, 92 mm diameter) mounted on a square section rod (15 mm) with a ring forged in the end. The two bars slide on each other, so that the overall length can expand from 510 mm to 930 mm. It should be noted that the bar shot is made of wrought-iron and, as a result, is rather corroded, so that some of the measurements may be a little short. The other expanding bar shot, BA T 8480 is fragmentary, but the overall dimensions can be reconstructed. The overall length is 390 mm and the unit would expand 10 a length of 680 mm. The disks are 110 mm in diameter and 40 mm thick.
