You hunt with what you have.
With the $300 farm store AR clones, it's used a lot.
I'm a big fan of states restricting caliber to the game hunted, forcing idiots to use an appropriate caliber for the game in season.
I've seen too many deer gut shot by some idiot with a .223 AR or SKS or AK clone.
Sickens me every time I see it.
In my state, the .458 Socom became legal for deer.
Idiots paid twice retail to get them, then shot deer to pieces just because they could click off a dozen rounds...
What you can't get through the 'Black Rifle' bunch is, it's always been, and always will be first shot placement.
If they think they don't have to practice shooting because they can click off 2 or 3 rounds per second, this crap is going to get worse.
Some history for the ignorant,
(Ignorant isn't stupid, just means you don't have an education in the particular subject, while stupid is you know the difference but do the same thing anyway)
The .218 Bee is the grand father of the current .223
It is a rimmed .22 cal, center fire round with .218 bore & .222-.223 rifled groove diameter.
Beginning to see where the .222-.223 family came from?
This was exclusively a small varmint round, never intended for large or dangerous game, and the predominant rifle at the time was tube fed lever action, so flat or round nose bullets in the 30 to 45 grain range.
Rifling was 1:16" or 1:14" depending on the rifle manufacturer.
The father of your AR-15,
When bolt action became popular, Remington being a bolt rifle maker, introduced the .222 Rem round.
This was a modern powder, high velocity bottle necked case specifically designed to outshoot the Winchester .218 Bee & .219 Zipper.
Rimless for smoother feeding in bolt rifles, and with a pointed nose, this round was designed to be fired from a post WWII rifle with available optics.
With 35-50 grain jacketed & pointed bullets, this round could reach 3,000-3,500 FPS and made a mess out of smaller varmints.
Again, light weight bullets out of a relatively slow barrel twist, usually 1:14" and later with heavier bullets, 1:12" twist.
The .223 Rem is slightly more powder volume version of the .222 and was adopted by the US military & NATO as the 5.56x45 NATO round.
The military, being schizophrenic, had to mess with everything...
Starting at 52 grain bullet weight, 1:12" barrel twist rate and IMR extruded (stick) powder, the little round retained it's 'Inherently Accurate' status,
And in the early Eugene Stoner rifles it worked fairly well in short range jungle enviormental.
Then the military got involved...
Bullet weights shot up because ballistic testing (at ranges the round wasn't intended to shoot, on animal sizes the round was never intended to be used on) didn't turn out well.
The next idiot idea was to change from much cleaner burning IMR powder to old military ball powder that was corrosive and murder on the gas system.
The next stupid idea was to declare the rifle 'No Clean', not developing or including a cleaning kit.
Now, the schizophrenia continues,
The military continues to shorten the barrel, increase bullet weight and expect the same or better results in velocity & terminal ballistics...
The stupid heavy bullets (77 to 99 grains) require barrel twist rates that damage the barrel, in the neighborhood of 1:6"-1:7" commonly...
And now that patents have expired & the design is in the common domain, every fly by night outfit that can crank out parts is doing so with little or no quality control.
Nothing like getting your $299 farm store & discount gun store special with it's $12 made in China barrel & plastic sights that shoots 'Minute Of Barn Door' groups...
But most guys buying AR clones don't care, there are 30-100 rounds in the magazine so accuracy of any kind isn't an issue...
"Hunting with an AR" is an oxymoron.
It's all about the FIRST shot, not the 30th!
I CAN build a sub MOA AR clone, it's not going out the door for $299 or even $599...
(A good barrel can run $500)
And it's not going to be sub MOA very long if you click off 30 round mags of discount ammo.
