After reading Mr. Boddingtons article in the March Rifleman about the .400 H&H cartridge I decided to make up a dummy of it for my African calibers display. I simply ran a .375 H&H case into my .416 Taylor decap/expander die then a slight flaring of the case mouth then I seated a .416" Hornady 400 gr. SP. I must say that it is an impressive looking round, even if it is a dummy. It looks great among the other H&H dummy rounds I have along with other big bore rounds in the display.Robert
