I would have previously thought a semi auto was unnecessary for hunting big game, but after helping a neighbor dispatch some wild hogs on his land, I would have to argue otherwise. The vital area even on a large hog is small, and they run a good ways even when you get a good hit. Shooting semi-autos definitely helps in recovery of an animal like that. So from that standpoint, I would have to say semi-autos are needed, if you care anything about the animal. In Canada you've got moose, wolves and bears to deal with, so I would think a semi-auto or a big handgun would be a must. Something tells me the folks who want the new gun rules won't be walking around hunting in bear country.
