one of the best examples of weapon choice in a canoe adventure that turned into a survival walk out was the Hubbard and Wallace 1902 trip into what was then unknown parts of Labrador.along with their guide George Elson they went into what they thought would be Caribou hunting grounds so they had high powered rifles.along with long barrel 22's for pot shooting that was all they had against good advice to have a shotgun.no Caribou were found in any large numbers and only one was shot.the 22 got a goose or two and if they had the shotgun they could have got many more.it was one of those "three went in,two came out"story's.many mistakes and some very bad luck was also involved but with the right gun they all could have got enough meat to hold off starvation and get everyone out.i always suggest "the lure of the labrador wild" as a good read for anyone who spends anytime in the outdoors.
