Heres What to Use it for
Header image from AmmunitionToGo.com
Debates between different cartridges superiority is always a big discussion for gun enthusiasts at every gun club. Sometimes views from die-hard .308 users or .223 followers can be too one sided to reason with. Both cartridges have valid points to support their case. Lets take a comparison perspective between the .223 and the mighty .308 and see what its good for. Just to let you know this comparisons is not to be technical for the gun nut but for the layman’s gun enthusiasts.
For the most part, the .223 Remington has a flatter trajectory than the .308 Winchester out to 500 yards. However, the typical .308 Winchester load has more than twice the muzzle energy than the .223 load.
Also, the heavier bullets with a higher ballistic coefficient used by the .308 retains more energy and velocity than the lightweight .223 bullets.
So basically, the typical .308 load usually has as much or more energy remaining at 400-500 yards as the .223 does at the muzzle. Which makes the .308 Winchester a much better choice for long range shooting.
With that in mind, the .223 Remington has a flatter trajectory at short range, and the recoil is less than the .308 Winchester. Felt recoil will vary from shooter to shooter and rifle to rifle, but free recoil energy is still a useful way to compare the two cartridges.
Both cartridges are used extensively in the military and police sniping operations because of its accuracies. Because its hard to choose an outright winner when it comes to accuracy between the two popular cartridges. Basically, for short range use the .223 and anything past 500 yards stick with the .308 heavier bullet. The .308 retains more energy and are less susceptible to wind drift.
Understanding what each cartridge is capable of helps us in choosing the caliber to go with and what we’re hunting. To simplify this the .308 is best used for taking down big game and the .223 can be used to hunt medium to large sized game.
Can you use the .223 for deer hunting?
Despite having less knock down power of the two, the .223 is perfect for varmints, coyotes, hog control and deer.
What is the range of .223?
The .223 ranges is effective from 400 to 600 yards but with less energy and knock down power than the .308, the .223 is more useful at shorter ranges. With the advancements in cartridge innovation, the .223 can reach out to 1,000 yards.
Since the .223 has a lighter recoil than the .308, this may be the thing to have if your hunting situations requires lots of follow-up shots like feral hogs control.
What is the effective range of a 308?
In the military the US Army emphasizes an 800 meter maximum effective range for the .308, the Marine Corps preaches a 1000 yard (915 meter) max effective range. For most hunt you won’t have to shoot at these ranges but at 400 and beyond you’ll be able to bring down the big game without a hitch.
In summary the flat trajectory and lightly constructed bullets most common with the .223 Remington make it great for taking shots at small, thin skinned animals like prairie dogs, bobcats, and coyotes.
The .308 on the other hand shoots heavier, larger diameter, better constructed bullets, and the .308 Winchester has a clear advantage when hunting larger species like deer, caribou, elk, and red stag. The .308 may be light for moose and grizzly/brown bear, but it will work with good shot placement.
Home Defense & Target Practice
When it comes to home defense the .308 cartridges is suitable for its stopping power. Even if you go with the .223 there are many good semi-auto rifles with quality ammunition available at a reasonable price.
.308 – Using this heavy round for home defense is kind of expensive and not the thing to consider. But if your purpose is for target practice and you compete as an F-Class shooter, then you’ll be going through rounds by the thousands per month. For a quick tip on choosing the bullet weight consider what your barrel twist rate is, here’s a quick guideline:
- 1:15 twist: up to 150 grains
- 1:14 twist: 150 – 168 grains
- 1:12 twist: 168 – 170 grains
- 1:10 twist: 170 – 220 grains
- 1:8 twist: 220 grains or more

We can go on and on with this comparison but the bottom line is what are you going to use these cartridges for? We’ll just recap with the main Q’s and answer.
Do you want a cartridge well suited for hunting big game like deer, elk, or bears? Get a .308 Winchester since it’s much more powerful and there are lots of great ammunition choices designed for that sort of hunting.
Are you looking for a cartridge to hunt predators and small game animals with?
Both will work, but the .223 Remington is the better choice here because it has a flatter trajectory, ammunition is cheaper, and there are many types of .223 ammo specifically designed for predator and varmint hunting.
Are you very sensitive to recoil? Go with the .223 Remington as the recoil that cartridge produces is virtually non-existant.
Since the difference between them (223 vs 308) is pretty big in certain respects, each cartridge is better suited to specific situations than the other.
Here’s an entertaining perspective from Demolition Ranch’s Version
Sentiments from The Firing Line Forum on this subject
threegun – I periodically rethink my self defense weaponry from the ground up. My handgun and shotgun are good to go however I’m questioning (in my head) my AR-15’s in 223/5.56MM. Not the platform, as I’m very satisfied with the weapon itself, but the caliber.
I’m seriously thinking of adding the AR in 308 to my stable with intentions that it replace the 223 as my primary go to rifle. I would like your opinions pro and con on why I should or shouldn’t switch.
jmorris – What are you defending yourself against? How Many? Where at? For how long? At what range?
Creature – I would say that for self-defense, an AR chambered for .223 is a better choice for CQB (ala “self-defense”) than one chambered for the .308. The 308 to me is more of a “reach out an touch someone” kind of cartridge, whereas the 223 is an “in your face” kind of round. I may be the last of the Mohicans for thinking and saying this, but I consider the 223 to be just fine for CQB and short-medium range engagements. I consider the .308 better suited for medium to long range engagements, which in my opinion are NOT self-defense distances.
dalegribble – I agree with creature. Adding a 308 won’t replace your 223. They are 2 different cartridges for 2 different purposes. Look to the military and see the number of guns deployed in each caliber, the 223 far outweighes any other caliber in the number of guns issued.
If you feel the need for a 308 (as I do) then add it to your system, I’m sure you will be glad you did. Only you will be able to determin if it will replace the 223 as your goto caliber.
overkill556x45 – I would lean toward the .223 because ammo and magazines are cheaper than .308 ammo and AR-10 mags. The AR10 will get expensive fast, as mags go for $30-$50. In addition, cheap 7.62nato surplus is drying up fast (all surplus is drying up fast). If you’re going to reload (which is fun in and of itself), both can be affordable, but the .223 will be pretty cheap in comparison.
As far as application of force, your follow-ups can be faster with the .223. The .308 will obviously open up a bigger hole in your foe, and do it at longer ranges. However, on the civilian side (meaning not stuck with M855 ball ammo), the .223 can be loaded up with bullets like the Vmax and others that expand faster and should cause more catastrophic wounds than a standard ball round. Also, a .308, if used in a home defense situation, stands more of a chance of WAY over-penetrating (though more frangible rounds are available) and going through the BG, the wall, the exterior, down the street, etc. The .223 shouldn’t over-penetrate as much.
Really, it comes down to the intended use. Short-med range, I’d go with .223. Med-long, .308 win. Another consideration is how much money you want to spend. Either round is pretty versatile.
kraigwy – Ask me a few years ago I’d said the 308, having shot my M1A and have gone through and tought snipers schools using the M21.
However of late, I’d have to vote for the 223. Its beat all the 308 highpower records, even beating the 308 in Service Rifle 1000 yard matches.
The 223 is cheaper to shoot, both in factory and reloaded ammo. A good match AR is about a third the cost of a Heavy Match M1A and easier to shoot.
The 223 has allowed younger shooters and ladies to compete with us old folks.
At a small additional cost you can get an extra upper for shooting Mulit and3 gun matches without burning out your Match rifle.
If you want it for home defence you can get the shorter barrel of the M4 configeration. You want a varment gun you can get 50 grn bullets, you want a long range gun you can get 80 grn bullets. You dont have that versatility with the M1A.
Thats why its called AMERICA’S RIFLE.
2transams – Here’s my zero cents (it’s the internet,my opinion is not worth two cents) :
.223/5.56 is an extremely versatile round,and can be loaded with any and all types of bullets. Low recoil in a lightweight weapon make it excellent for CQB situations. Based on my observations of the layout of the town where I live and tales from friends and family who have seen combat in the Middle East,in any type of urban situation you will very likely not be making shots past 200 yards,where the 5.56 round is plenty ’nuff. But that’s already been discussed,moving on…
For me,even with a sling on the rifle the .308 is much harder to take faster follow-up shots. The recoil is harder unless you go to a heavier weapon,which to me defeats the purpose of a light-‘n-handy battle rifle. I really wouldn’t want to run around with a full-size M1A,and the SOCOM 16 puts that big ol’ thunderboomer pretty close to the face,I didn’t care for it,and I didn’t shoot well with it.
Now a good, heavy, accurate .308 seems to me would be great from a fairly secure position where you can take good clear shots,and you know you’re good for 100 yards on out. In that instance,bigger is better.
Just my zero cents.
