When you say Air Rifle you are referring to a pellet rifle not a firearm. At present there are no 300 Cal air rifle being made.
No. .243/6.5mm is the minimum allowed for deer in NC.
In the state of Missouri Its perfectly legal to hunt with a black powder rifle during deer season. In all counties
Yes, subject to legal restrictions which vary from state and even within some states. The 30-30 is considered the classic deer rifle.
Maybe. Depends on where the deer is shot, from what distance. Much more likely to WOUND the deer- which is why in most US states, it is not legal to deer hunt with a .22 rimfire.
Yes
.243
it is legal to hunt deer with a 223 in wv but it only has to be a .25 cal for rim fire
Yes, it is legal. Texas does not permit the use of RIMFIRE guns for deer hunting, but any centerfire is legal. Wh ile it is legal, I personally do not recommend it. Yes, the .223 can kill a deer. It will also wound a lot of deer. It is simply too small to insure a clean kill.
no
No
No. Georgia law requires rifles or handguns used for deer to be 22 cal CENTERFIRE or larger, with an expanding bullet. While .220 Swift, or 22-250 is legal (with the right bullets) a 22 Long Rifle (rimfire) is NOT legal.
Whitetailed deer and similar sized or smaller animals.
