that is why i asked what you guys as hunters used for:
here is the regulations for NWT:
FiReaRMS and aMMuniTion
All licenced hunters when hunting big game in the NWT,
you must use a .222 or larger caliber ammunition to hunt
wolf and wolverine. To hunt wood bison, ammunition
must not be less than .30 caliber. When hunting polar bear,
ammunition producing less than 2,800 joules of energy shall
not be used. You may use a .243 or larger calibre to hunt other
types of big game.
For the purpose of hunting big game, rim fire ammunition
is illegal.
Ammunition containing non-expanding bullets, steel-jacketed
bullets or tracer ammunition may not be used for hunting.
in the Yukon it is the same and before the ban a lot of people used the 223 in mini14 to get caribous while the minimun is set up for the 243 as in NWT ....
