..so, is it worth attempting a further contribution to his meagre education?
The 10-bore Paradoxes WERE specifically designed and marketed by Holland & Holland for use against pachyderms!

Care to enlighten us with a few references, 500brains?

Meanwhile, here's one of my favourites: an observation by R.C.F. Maugham, His Majesty's Consul-General at Beira, Portugese East Africa (and inveterate big game hunter), writing just after the turn of the century.

"....no hunter in his right senses should place his blind trust in such a weapon as even the .450 cordite rifle to extricate him from the thousand and one dangers by which he is liable from day to day to be confronted in Africa. I therefore unhesitatingly advocate, in addition to the most perfected type of modern high-velocity weapon which we are ever likely to see, the inclusion of a sound, heavy rifle intended for use at close range, the shock of whose bullet, even if it should not instantly kill, will assuredly be sufficiently great to disable or turn a charging beast. For those who do not possess the strength to use a heavy eight-bore, which I look upon as the ideal weapon par excellance for this purpose, I would suggest the adoption of a 10 or at least of a 12-bore Paradox throwing a 1 3/4 ounce bullet, driven by a charge of five drams of black powder. This, in capable hands, should be sufficiently powerful to produce the desired stopping effect."
