you do know thats not what kills them right?
they then have thier throats cut and they bleed to death. the bolt stunner is just so they don't feel pain.
Isnt it lucky nature isnt so choosy when animals eat one another. We (some) get all cut up (pardon pun) about taking more than one shot to kill an animal, and howmany bites, claws, pecking etc does it take an animal to kill its prey. I wonder does a lioness think to herself while she slowy stangles and claws a zebra "oh only if I had a bolt gun it would be so much kinder" or does a Eagle think "I wish some one would teach me how to electrocute the fish I catch out of the river so when I impale them it doesnt hurt too much"
Pffft We strive to be as humane as possible, it doesnt mean we stop doing these things because 1 in 10 is not a instant death, we may as well join the lettuce eating tofu nutjobs if that was the case.
Ethics are for people who have the luxury to miss and not go hungry, try telling that to a native american back in the day or a zulu tribesman, I wonder if they would think "oh wait before I throw my spear" will it be a head shot" or does one think they though "shit food, throw something at the bastard so it cant run away" lol
