Hi Bill,
An archaeologist friend of mine in New Zealand is trying to identify the large bullet in the centre of the picture. It is .577 calibre & 34mm long, and has a solid base. Any idea what it is??
 
It came from a frontier town in N.Z. which saw quite a bit of activity in the Maori Wars. It was found with other c1860 militaria. The town had a large garrison, the actual property of the find was owned by an officer. Speculation has ranged from a .577 proof bullet for proving barrels to an explosive bullet (some were used there apparently). �Or a civilian gun perhaps? Regards, Adrian.
 
Hopefully one of these image �links will work....
