That poster is evidently the individual who has created most of the pages on the double rifles as well as the page for the movie "The Ghost and the Darkness" on that site. I get the impression that he would welcome any input since he admits that what he knows about dangerous game rifles has come from research only - like me. Might not hurt to cut him some slack. Could be he's afraid of you folks and therefore is worried about posting here. I'm not.I will readily admit that I'm an enthusiastic layman when it comes to dangerous game rifles.
