Here in Ontario , you can use an Antique Handgun for hunting , except no big game. If you want proof , then read the
Ontario Out of doors magazine , (Volume 50 , issue 7 , Aug. - 2018 ) on page # 22 , where ,,,,,,, David Critchlow
( MNFR Enforcement Specialist ) answers this question .
Others claim the .455 is the most potent Antique Hg. for bears. After test shooting mine in several pieces of wood , I believe
it would only piss him off. The Howdah would be the answer as it was made for attacking tigers . Finding an original ( antique)
would be expensive .
Clearly a short NR shotgun is the only real answer.
