Interesting! In Alberta you must use 23 caliber and up! It was to stop animals from being wounded and getting away. Extremely outdated law as when it went into existence .223s didn't exist!Wow. What's the theory behind that.
In my province you can't hunt with a caliber larger then .224 pill once you tag out on your deer. Apparently this law is being changed as there is no evidence that hunting with a larger caliber will stop poaching
