Not too much to tell Jim...I've done metal detecting on and off since the mid seventies and have found hoards...of rubbish!!!..lol!!
Most times I go out I find some pistol or musket shot and probably now have a few hundred...I do curse airgun pellets though, so small, they take some separating from the mud....
Favourite find is a Bronze Age axe head dated about 1500 BC...lovely to look at and handle...
