With a .22? My word. Where do they shoot'em? In the head?
Yes.
I remember reading also that the Mafia prefers .22 guns for their "hits". They get in real close, take good aim, and there is less noise.
Bullet placement is everything.
We're not talking a humane kill here. Many .22 hits would cause a coyote-sized animal to die from internal bleeding, even if the hit wasn't immediately fatal.
There has been a moratorium on Polar Bear hunting since 1973.
No hunting from aircraft or motor vessels and in some regions only Inuit can hunt bears.
As for shooting a Polar Bear with a .22, a .22 caliber would bounce off a bears noggin like a chick pea and wouldn't even penetrate the fur and hide let alone four inches of fat.
The Inuit hunt with .303s even then Polar Bears are extremely dangerous prey.
I've seen one running away at 40 miles an hour after being wounded and it took half an hour to take it down from a helicopter even then it reared and took a swipe at the helicopter.
