After the Dickson blew up, it took him 32 shots using the Moore and Purdey 16 bores alternatly to kill an elephant. Things got better when he traded some ivory for the Westley 10 bore and proceeded to harvest many elephant thereafter. Some with huge ivory. It seems the Purdey was only used as a stand-in; probably why it survived at all. It was regulated for round ball and only 1-1/2 drams powder. With the rifle is a long handled mold for a short conical bullet along with the ball mold.
