Description

Five round shot, all c.112-114mm range were discovered in the concreation underneath SCW25 and match up with SCW25’s bore of c.120mm.

These weighed approximately 2-4kg, however due to their length of time underwater most of the iron would have leached out into the concretion graphitising the shot and making the weight unreliable.

By calculating the original volume of the shot and multiplying this by the density of cast iron (6800 to 7800kg/m³) these shot would have originally weighed around 5-6kg or 10-12 Amsterdam ponts (494g)
