A friend of mine recently found this ball within feet of 2 other 6 pdrs and a 12 pdr. The "fuze hole" in this one is unusually small, about 12mm. My thoughts were that it was a grenade rather than an artillery shell. It's fairly graphitized so the weight is probably meaningless but it's coming in around 2.8 lbs. The graphitization has also affected it's shape a bit. It is very soft.
