Some quotations from Baker's "Eight Years Wandering in Ceylon":

....there is one point upon which all are agreed, that no matter what the size of the bore may be, all the guns should be alike, and the battery for one man should consist of four double-barrels .....

MMmmmmmm, four double barrel all alike.

More .......

"The size and the weight of guns must depend as much on the strength and build of a man as a ship's armament does upon her tonnage; but let no man speak against heavy metal for heavy game, and let no man decry rifles and uphold smooth-bores (which is very general), but rather let him say, "I cannot carry a heavy gun," and "I cannot shoot with a rifle."

Obviously they had vigourous debates in their day too!

"There is a vast difference between shooting at a target and shooting at live game. "

As true today as then.
