can anybody tell me what cals i can use for hunt in any province

[MiG25]

In B.C. ammunition to hunt bison must be constructed with
a 175 grain or larger bullet, which retains 2,000ft lbs or more energy at 100 m.

No other restrictions for big game with centerfires in B.C., some animals do require a minimum 20 gauge shotgun though.

don't forget that there are a few "shotgun with shot" only zones (ie buckshot, no slugs) in BC.

Sasscratchewin is .23 or larger. No FMJ's or non-expanding projectiles on big game.

Saskatchewan has at least two primitive weapon zones only, for big game seasons.
(shotgun/muzzleloader/bow) I am sure a crossbow fits in there, somewhere too.
