It depends on what you mean. If you mean legally, many U.S. states require a caliber larger than .22 or 223, however, that IS legal in some states. If you mean what caliber will kill a deer, almost any rifle caliber will, but .22 or .223 is questionable, which is why many states prohibit that for deer hunting.
If you're VERY close and you have pinpoint accuracy, you could potentially kill a deer with a .22, but the smallest caliber you could realistically use to kill a deer would be a 7mm rifle.
In ny its center fire cartridges only so 223 or 5.56 NATO with a max capacity of 6 rounds
BB guns are NOT for hunting. It will not kill a deer. The Answer is NO.
No.
No, no air rifle has a capablitay to kill a deer. The maruader is a great gun but it can only kill up to a rabbit or mabye a fox. If you try to shoot a deer with that it will charge at you or it will just shake it off.
I love answering hunting questions but sadly the answer for this is no. You see a BB ball doesn't have the power to reach a vital organ. The only thing the deer will do is run away and think... Was that a Pebble? So BB balls won't do any damage,but pellets. Well pellets have the power to really injure a deer but not kill it. So my conclusion is...You can not kill a deer with a BB gun.
Yes, there are several pre-charged, and break action pellet rifles that can more then kill a deer. They even use them to kill Wolf and Coyotes. However, you'd need a rifle with 16+ foot pounds to reliably kill large animals.
Most likely the deer would win the fight. A buck with sharp antlers and strong hooves can kill a man by striking him with them, but if the man had a sharp knife, he might kill the deer. Even if the deer had no horns, the deer can still kill the man by knocking the man to death with its head. You just need a gun. Bang. We win
While a BB gun does not have a lot of power, you still may be able to kill a deer with one. It is unlikely, but depending on where the animal is shot and if the BB is strong enough to puncture the skin, it is possible.
key deer are the smallest white-tailed deer
it may kill a deer if you were lucky. But it is not the best choice for hunting deer. Remember a .22 pellet is the same size slug as a regular .22 cal bullet and I would not hunt deer with a .22 cal rifle. It's just a poor choice.
Mouse Deer
The smallest subspecies is the key deer. They are found only in Deer Key, Florida. A full grown key deer averages 70 to 80 pounds.
the bet gun to deer hunt with is a 30-06 or a 308
