Which one is better when it comes to .308 Win vs 5.56 Nato? That’s often the question gun enthusiasts ask. These are not the only two rifle cartridges globally, but they are among the most popular ones. So it’s not unusual to compare the 308 vs 556.

.308 vs 5.56 Nato Uses | 308 vs 556
While both are fruits, they couldn’t be different from each other. But, of course, one may be better than the other, depending on the situation.
If you’re prepping for the zombie takeover, you’ll likely want to have two rifles, one chambered in each. While the bigger of the two is better ballistic-wise, the 5.56mm will be more abundant.
It makes a great addition for when it’s time to start putting zombies out of their misery. Semi-automatic rifles using Winchester Nato rifle ammunition will likely do the job.
Bolt-action rifles chambered in the correct bullet rounds are just as deadly. You can also use both of these cartridges for defensive and hunting situations.
The similarities end there, however.
If the primary goal of your weapon is to stop an advancing enemy, the top performer will be the .308 all day long. The same is true if you want to hunt deer.
Regardless of the barrel length, it’s the bigger cartridge that contains more powder and a bigger grain bullet.
Let’s take it a step further than gun users all know to be correct about these two.
After all, there is always more that goes into it than ballistics.
If you only want to do some target practice for fun, the 5.56 will likely be your best bet based on the cost. However, its usefulness also extends to the tactical department.
.308 Win vs 5.56 Nato Cost | 308 vs 556
Now, compare the 308 vs 556 ammo cost. Usually, bigger projectiles, which are 308 ammo, cost more money.
There are a few reasons for this. First, to keep it simple, they need more material for production.
Because of this, the 5.56 Nato ammo is cheaper by about $6 to $7 per box of 20 rounds. Therefore, reloading with these bullet rounds is slightly less expensive than the other.
While that much money doesn’t seem to break the bank, a closer look reveals the opposite.
What if you believe running 20 ammo rounds through your rifle every week for a year (52 weeks total) will make you a better shooter? You will wind up saving over $300 if you choose the 5.56.
Of course, shooting a gun is like eating potato chips. You can’t eat only one pack.
In other words, who goes to the range and only runs 20 ammo rounds through their rifles?

Confidence in Shooting 308 vs 556
Confidence comes from constant practice. You heard the saying, “Practice makes perfect.”
Not everyone may agree with this statement, but most understand the philosophy.
If you want to be a great shot, you need to practice shooting regularly. If you’re going to practice more with the smaller cartridge because it costs less per round or is an overall more manageable cartridge, that is the better choice for you.
There is another thing to consider when talking about confidence in shooting. It is the amount of felt recoil that will hit your shoulder with each steady squeeze of the trigger.
What Is Recoil? It is the gun’s backward movement after firing the weapon. In principle, it balances the forward momentum the gun gained during shooting.
If you feel like someone is punching you in the arm each time you shoot, you may want to opt for the smaller of the two.
Plain and simple, when it comes to .308 Win vs 5.56 Nato, the former packs a bigger punch. Note, though, that shooting an AR in 5.56 is like firing a bazooka if you listen to some guys.

Think about the costs involved also. Decide what you need the gun for.
These steps will help you choose the right one between the two.
Don’t forget, though, that these are not your only options. There are more of them, so you may want to give them a try.

When I was in Viet Nam (66 – 68) I had to opportunity to fire on a regular basis. I carried the M-16, M-3
(Grease Gun), the M-1 and even the ’03. Out section had a strange collection of weapons for a comm
unit that never left base. I found all of the tremendous fun to go to the range with several boxes of
ammo and be able to shoot to my hearts content. I also learned about the problem with the M-16
at that time frame and experienced failure that were consistent with the cleaning of the weapon. It
soured me on the weapon. Since that time I have had to opportunity to fire different configurations
of the AR platform rifles chambered in both the .223 round and the .308 round. I must admit with
the minor changes for the most part I really enjoy the new AR platform much better than the old
Viet Nam era weapons. A friend of mine with has a rifle from the early Viet Nam era that he acquired
and has the license to keep a fully automatic weapon) which he breaks out from time to time to compare
it to the newer version of the weapon. While it is the same weapon and the changes are internal it is
almost like night and day in shooting them. For shooting hogs the .223 is still a blast but to take one
down with one shot consistently I will take the .308 ever time hands down. I prefer the Bold
action rifle over the AR platform in most circumstances as it is more accurate for me at the ranges
Obviously the author of the article has never seen a gsw from a 5.56 first hand. I do agree with the thinking of a 7.62×51 in combat but I beg to differ on his statements on the 5.56 in combat. I have seen time and time again on the handy work of the round and believe me isn’t pretty by any means and it’s even more devastating if the round is either a HP or PSP.

Of course the 308 is stronger and I enjoy it for what it is. I have killed/harvested many pigs and deer with the 308. But everything depends on what bullet you use and shot placement. With the wrong bullet (168 gr Match) should not be used for hunting: It zips right through without expansion. It 308 coming in and 308 going out. I have harvested MANY hogs with the 5.56 and it works great even with FMJ but a better bullet can be selected: One that does not explode like a varmint bullet. Most 223 bullets are built/designed for varmints here in the US. I select the Sierra 65gr SP as it has a thicker jacket designed for rapid expansion instead of fragmenting. The Germans have been using this type of bullet for many years on hogs and deer and it works wonders. This is what I use for almost everything. I reload for it and the added benefit is extreme accuracy. They make a factory SWAT load just like mine but it’s very expensive. Other reasons why the 223 works great: The AR 15 is lightweight and easy to maneuver in the woods. (I do have an AR in 308 and it’s handy too.)
Being retired military an a Viet Nam vet I have used an M14 and M16 the M14 7.62X56mm is way more powerful than a M16 5.56X45mm I preferred the M16 WHY I could carry more ammo most of the time I would load out with 500 or 600 Rounds no way I could carry that in 7.62
When shooting the .556 the shooter was on his knee for what seemed to be more of a direct shot. With the .308 he was standing up which would be a different angle of penetration. Why didn’t he shoot both rifles at the same angles?
