Canadian hunters: what calibre cartridge was being used to hunt small game in the early 1900s before the .22 became so popular ?

Canadians were not allowed to have guns so they had to resort to shouting insults at small game in hopes of shaming them to death.  This was rarely successful.

And what is hopefully your final act of trying to be relevant on this dying forum, this final question of yours has been largely ignored by the entire hunting community of Yahoo answers. This is fitting and a fine example of the lump sum of your total contribution to this page.
