Figure 7.28: The smallest composite lead-iron round so far recovered from a battlefield is that from Towton (Towton find 1013). It weighs 148 g and has a diameter of 30 mm. Assuming a windage of 3.2 mm, based on that quoted for seventeenth-century small round shot, this gives a gun with a bore of about 33 mm. This is just beyond the upper limit of the Dutch hand-cannon and so was probably fired from a small artillery piece.125
