5 Best M1A Ammunition
We have been accustomed these days to weapons constructed of composite products from the Space Age and chambered in tiny sub-caliber ammunition.
Constructed from teak and steel, the regular M1A uses a strong 7.62×51 mm NATO cartridge.
The United States is among the latest battle rifle prototypes.
Officially introduced in the late 1950s and designed for European warfare, the Army M14 rifle.
While the post-war infantry weapon production of the Soviets was targeted at moderate 7.62×39 projectiles called M43, the U.S. military updated the .30-06 Springfield or .300 Savage (depending on your source) and accepted a modern NATO round of 7.62 51 mm, a typical full-power combat rifle round.
The M14 was used from the mid-1960s to the early 1970s, but, due to the Springfield Armory M1A rifle, it continued to function as a civilian variant.
Considerations of M1A Ammunition – Things to keep in Mind
The M1A is a semi-automatic-only variant, designed for sport-shooting and hunting, unlike a service select-fire M14.
If your M1A’s basic purpose is not casual shooting and plinking, then the style and consistency of ammunition are certainly considerations that will make a difference in the precision of your firearm’s durability and your entire shooting experience.
The Springfield Armory M1A is equipped to fire .308 Winchester or 7.62×51 NATO regular factory ammunition, since the two styles are basically the same.
There are very small variations, in fact, but 7.62×51 and .308 Win are not quite the same thing.
Shoulder to shoulder, the latest .308 Winchester sports round is nothing better than the upcoming 7.62×51 mm NATO military round.
The .308 and 7.62×51 are compatible, with nearly equivalent physical measurements, although all cartridges use a real projectile diameter of .308 inches (7.82 mm).
The distinction between them is inside the cartridges which relates to the thickness and powder volume of the case wall.
Another more theoretical concern can also be seen on the site which applies to a particular cartridge primer specification.
Unlike stronger combat ammo primers, as the bolt slams forward, civilian ammunition uses primers that are more vulnerable and an elevated chance of primer detonation.
This is a rather remote possibility, however. When shooting the weapon, if you have barrel discipline, then all is good.
Since the NATO 7.62×51 mm military rifles are designed to have effective feeding and operation with the use of ammunition manufactured worldwide, they typically have longer headspace in the chamber.
This is the gap from the bolt’s face to a point in the chamber that stops the cartridge’s forward motion.
The headspace for the 7.62×51 mm NATO is between 1.6355 and 1.6405 inches, and for the .308 ammunition chamber, the headspace is between 1.630 and 1.6340 inches.
Although the Sporting Arms and Ammunition Manufacturers’ Institute (SAAMI) may not think it unsafe to shoot the .308 ammo in NATO cartridge chambered guns, you can just fire 7.62×51 m NATO in 7.62 chambered firearms and .308 Winchester in .308 rifles to keep yourself ultra-safe.
While the exterior dimensions of both cartridges are identical, thicker walls imply fewer powder capacity and lower pressure and velocity.
Because the 7.62×51 round has stronger case walls than .308 Winchester cases, more propellant will be taken by the commercial .308 brass, allowing them to be filled to greater pressures than the NATO 7.62-51 mm military.
Up to 62,000psi (427 MPa) can be filled with commercial hunting ammunition, although the 7.62 NATO bullets are loaded at a overall average pressure of 50,000psi (344 MPa) and are measured at 67,000psi (462 MPa).
A grain is an incredibly tiny measuring unit for mass. The grain (abbreviated ‘gr.’) is used to calculate projectile weight, and the propellant or gunpowder, in the weapons niche. It basically suggests that the bigger the grain, the heavier the projectile.
Although bullets (projectiles) will weigh up to 750 grains (.50 BMG) for the lightest calibers (17 HMR bullets) anywhere from 15 grains, .308 loads vary from 147 to 180 grains, the most popular form.
The uniform bullet weight is not too rigid, but you have to keep inside the golden middle, while general advice is to avoid steel-cased ammunition in a semi-automatic M1A.
This ensures you need to remain below 180 gr. Not to use something less than 147 gr., or 168 gr. Over 600 yards while fired.
Purpose of the Ammo
As with the scope or every other option of gun accessory, the first thing to do before determining is to decide the ammo’s intent.
Choosing the best .308/7.62 mm bullet weight depends on your planned M1A usage, so we break it down for you as rough guidance.
You may use any bullet weight you like for casual plinking, with an emphasis on small cost and proper functioning in your M1A.
However, the .308 bullets could be a safer option for aiming for optimum precision and heavier hunting, because they are less vulnerable to being thrown by the wind off track.
Since bullets that are too heavy are more influenced by gravity, 168 grain projectiles are suggested in long-range shooting for the best accuracy.
The strong 168-grain bullets are often needed for cartridges for deer hunting purposes, but for bigger game, such as moose, a larger 175-grainer is stronger.
Rounds that are heavier than 175 gr. Your M1A operating rod can get hurt.
In addition to weight, the construction of bullets is also critical in shooting, so many hunters often recommend hollow point and soft point rounds since they can kill easily and humanely.
Some hunters, on the other hand, do not advise using soft-tipped projectiles, mainly because the magazine does not often feed them reliably.
The second explanation is the soft bullet’s parts that end up in the rifle’s inner workings, which can then obstruct the entire firearm.
You will want to stick to using bullets that are a normal full metal jacket (FMJ) or “ballistic edge” form for target shooting, cartridges capped with 168-grain bullets made by a match-grade ammunition company.
It is also necessary to use certain tracer and armor piercing ammunition developed under NATO requirements.
You can, however, stop utilizing frangible loadings and any “light magnum” branded form of ammunition.
“Our final recommendation is the military FMJ as the easiest, safest deal, but not as exact as commercial ammunition, because you should hold a surplus of military ball ammo, but you can stop using the surplus stuff called” loose “or” bulk.

- Great value for the money
- Very reliable
- Steel cartridge is not allowed indoors
5th Best M1A Ammunition
Federal manufacturers American Eagle brand ammunition developed exclusively for target shooting, preparation, and practice for budget conscious clients.
For short to medium range plinking, Federal American Eagle Tactical ammunition has fair efficiency but is not as precise as high-grade competition offers from Federal.

This Federal 7.62×51 mm NATO Mil-Spec 149 Grain FMJ ammunition produces 2,750 feet per second of muzzle velocity and 2,437 ft./lbs of muzzle energy.
Since the AE Tactical loads are large FMJ all-around cartridges, they have 149 gr. A projectile with a metallic center drawn to magnets would not be ideal for indoor environments.
It is ideal for large volume shooters, as the Federal XM80CL ammunition is non-corrosive and has a non-corrosive boxer primer.
Verdict: 5th Best M1A Ammunition
Exactly the same round used in the M-14 and M-60 machine guns is the American Eagle XM80CL round and you can now use it without adverse consequences in your preferred M1A, any Sporter weapon, or other weapon chambered for .308 Winchester.
While the M1A is the world’s newest firearm credited to having “finicky” ammo, it should be viewed above all other factors as a mechanical system that depends on reliable ammunition.
You should not use cartridges that are dusty, wet, corroded, twisted, or damaged with that in mind. Additionally, you do not grease or mist ammunition with aerosol-type lubricants or cleaners.
Loads of hollow point or ballistic tip types of bullets fit well in M1A rifles, in addition to full metal jacket combat rounds, which would be ideal for reasonably short-range firing.
However, you would definitely want to stay with any of the match grade target rounds with the M1A for the highest precision and ultimate real-world practice.
