Yes........................
However, before you plan on going out deer hunting with this round, check your state's laws, because it may be illegal to do so. While many states allow a .243/6.5mm cartridge to be used for deer hunting, this is subject to vary between states, and your state may have a higher calibre requirement.
Yes.......
Yes - if you know where to aim.
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.
A 223 would be fine for a deer rifle but you need to make sure the (youth) person can hit the kill zone. I would suggest the 243.
Any caliber can do the job. Most states regulate what can be used.
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.
Yes. Common sense dictates that humans should kill deer by bow and arrow, lance or rifle, and not be stupid enough to go after it with nothing or just a hunting knife.
DONT DO IT!!! you will only hurt it. Only shoot it with a rifle. What if you live in Ohio and can't use a rifle Jack Wagon? If the right ammo is used and the right placement is done it will kill a deer Are you crazy? You would have to be extremely close to the dear to kill it with a 410 (10 meters at most) and a deer would hear you if you got close enough to kill it so its unethical. either shoot it with a rifle or in certain circumstances you could possibly kill it with a 12 or 20 gauge.
The 7.65mm Mauser rifle is MORE than adequate for deer hunting- IF a soft point hunting cartridge is used. Full metal jacket military ammo should not be used for hunting.
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.
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.
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.
