Dude. Are you for real? There is so much about this that just screams out fake, maybe just wanting “gun nuts” to talk here about killing deer with machine guns, or are you hoping for some wacko to offer to sell you a bazooka without a background check, etc., so that you can rail against them/the guns/the law/the NRA?
But......on the off-chance it’s for real, here you go with some generalities.
So much to consider.
The gun has to match the hunting style, terrain, weather, time of year, time of day, and intended game.
The gun has to match the hunter. Are you a big strong person, and can carry a heavier weapon many hours and won’t mind a gun with more “kick” (recoil), or do you want a smaller, lighter, lesser-recoil gun?
The gun has to match local law (some states do not allow semi-automatic rifles (just pump or lever or single shot), some allow only shotgun (buckshot, slugs) for deer, some require the bullet to be larger than .25 caliber, some let you have only 5 rounds in the magazine, some won’t let you have a small-caliber gun for squirrels on public property if deer are also open to hunt at that time, some won’t let you use 22-magnum (.22 WMR) even though it’s small caliber and rim-fire, etc. etc.).
The gun has to match the game. Shotgun with “game loads” for rabbits and squirrel, smaller shot sizes for doves, bigger shot and heavier loads for turkeys and ducks. Rifle bullets with adequate foot-pound energy at the terminal range you’ll be shooting (most all of them above .22 caliber do that), and shotgun loads (buckshot or slugs) of adequate energy for big game. And don’t let any anti-gunners, anti-hunters kid you, the AR-15 is a marvelous weapon for pigs and deer (if legal locally) and coyotes and groundhogs, etc., and the AK-47 semi-automatic rifle/round is just fine for deer and pigs.
The barrel length and sights have to match the game and local law. If a handgun for big game, then of the allowed caliber (usually .357 and up) and with barrel length 6 inches or more. If a shotgun or rifle, will the distances and ground cover/terrain need open sights or red-dot sights, or allow telescopic sights?
So, to the point, to pick a weapon to use, just ask your freaking FIL what he recommends, and what he will lend you to use!!! Do not go buy a gun, if you’ve never hunted or shot. What if you don’t like the experience, or get the wrong weapon for what you want to hunt now or in the future? Sure, you can sell or trade it, but why go through the hassle? Just use what you can that your hunting buddy (FIL, I assume) is also using or recommends or lends, and then after you get experience, if you continue, then get your own weapon of your choosing. At the minimum, you’re gonna need your hunting buddy/FIL to show you how to use the weapon and let you practice with it, including shooting it and sighting it in for your body, before you hunt!!!!
And....most states require new hunters to go through a hunter safety course in advance, and pass it, before you can even buy a hunting license. Those courses usually familiarize the new hunter with weapons and the issues above I hinted at.
Your state wildlife resources agency and your local gun-interest bulletin boards (on line) usually can help with information and questions, too. Examples are the Pennsylvania Firearms Owners Association (http://www.pafoa.org/) and the Florida shooters Network (http://floridashootersnetwork.com) and the California Firearms Enthusiasts (http://www.calguns.net/calgunforum/index.php), but every state and region has similar groups. Groups devoted to specific gun brands (Glock, Smith and Wesson, Sig-Sauer, etc.) also have subforums to discuss hunting and weapon information—google for those.
And join the NRA, it’s the premier gun owners/users advocacy group fighting for your right to keep and bear arms and hunt and fish responsibly. https://home.nra.org/
And no matter where you are, remember you’ll have to keep your gun safe while in your control—you might need a child-proof lock for the trigger, or a locking closet/box to store it, etc.
Good luck.
Is that right.?? I never heard of that....
