I just happen to be reading Baker online, and came across this most excellent quote.

"There is no more fatal policy in hunting dangerous game than a contempt
of the animal, exhibited by a selection of weapons of inferior calibre.
Gunmakers in London of no practical experience, but who can only trust
to the descriptions of those who have travelled in wild countries,
cannot possibly be trusted as advisers. Common sense should be the
guide, and surely it requires no extraordinary intelligence to
understand that a big animal requires a big bullet, and that a big
bullet requires a corresponding charge of powder, which necessitates a
heavy rifle."
