556 Vs 7.62 - No two rifle cartridges require a bigger comparison than the 7.62×39 versus the 5.56. One of America's favorite rifle cartridges. The other is the pride and joy of Russia, but still a very popular country.
Gunpowder has neither politics nor nationality. I judge rounds purely on in-flight ballistics, energy, recoil, price and availability. So we will compare these characteristics to settle the 5.56×45 vs 7.62×39 debate. if it can be solved.
556 Vs 7.62
Most articles like this start with a long history of the two periods they are comparing. I know there are thousands of other places where you can read about Remington or the Technical Committee of the People's Commissariat for Arms, so I'll give you a lecture. Let's start right away by looking at the dimensions of these two cartridges side by side.
Ak: 7.62x39 Vs 5.45x39
An obvious difference between the 5.56 and 7.62 is the bullet diameter. The former is a .22 caliber round and the latter is a .30 caliber round. This greatly affects bullet weight. The 5.56 usually has a 55 grain bullet, although bullets of 40, 62 and 77 grain are not uncommon. Its large diameter means that the 7.62 bullet is quite heavy. Usually 123 grain or very close.
Next, we consider the case capacity of two rounds. They are not so different from each other that they can store the same propellant. And considering that the 5.56 is loaded at a higher pressure, it follows that lighter bullets should provide greater muzzle velocity. It's just physics.
The 5.56 is a speed demon, often loaded for muzzle velocities in excess of 3,200 fps. The 7.62 doesn't stoop in terms of speed either, but the bullets typically exit the muzzle 20-25% slower than the 5.56.
The 7.62 we compared had a higher ballistic coefficient than the 5.56. But that's not enough to flatten the trajectory of 7.62 by 5.56. The 5.56's lighter, faster bullets are bound to have less fall than the competition because gravity gives them less time to pull them to Earth.
X39 Vs 5.56 Rifle Caliber Comparison And What You Need To Know
The flatter trajectory of the 5.56 makes it easier to aim from longer distances. You'll have better success with the 5.56 for longer shots, especially given that the 7.62 tends to go past 200 yards. However, both the 5.56 and 7.62 are reasonably accurate at ranges to within 100 yards, and most shooters will stay within range of their rifles anyway. Not even a single sniper round!
The 5.56 may outperform its competitors in terms of muzzle velocity, but the 7.62 bullets make up for this by weighing about 2 to 2.5 times heavier. This means it boasts excellent energy across all ranges.
Picking rounds for self-defense? Then you don't have to worry about which one is more powerful. A 7.62 or 5.56 will overwhelm a human-sized target at close range, so 20-25% more muzzle energy in the 7.62 doesn't necessarily mean it neutralizes the threat more effectively. A wider bullet creates a larger wound channel, so the final impact will do a bit more damage. It's the icing on the cake, so to speak.
The more powerful 7.62 is higher than the 5.56 for deer hunting. There is consensus that 1,000 foot pounds is the minimum energy required for ethical deer hunting. The 5.56 often doesn't deliver that much energy at 100 yards, while the 7.62 can easily extend a hunter's range beyond 150 yards. However, it is important to note that both rounds were developed to kill enemies of the country, not to hunt.
X39 Vs 5.56
It's important to step back, friends. I admit it's exciting to wield a weapon that kicks like a mule on bath bombs, but you wouldn't want to put up with that kind of abuse all day. Besides, heavy recoil complicates self-defense. The greater the recoil of the rifle, the more each shot will deviate from carefully aligned aiming.
At the end of the day, how much you actually need to withdraw is subjective. We can't tell you what you really feel. What we can do is objectively measure the recoil energy of an ammunition by considering four factors: bullet weight, propellant weight, muzzle velocity, and rifle weight.
Let's compare the recoil energy of the round above with real apples and apples. For this exercise, assume there are 24 propellant pellets in all 6 rounds. We're firing the 5.56 at the 7.75lb Windham Weaponry Dissipator Hvy. Bbl and 7.62 on a 7.7lb AK-47.
The 7.62 can have about 75% of the muzzle velocity of the 5.56, but with almost twice as much recoil from a much heavier bullet. It's important to consider that we chose a relatively heavy AR for this comparison. Heavy guns have less recoil, so if you fire a federal round from a 6.5lb Ruger AR-556, the recoil energy goes up to 4.22ft lbs.
Best 5.56 Ammo For Your Ar: 2021 Ultimate Guide
Certainly neither round returns an inconvenient amount. A normal-sized shooter can fire AKs all day long and never tire. Many people do. However, if you need less recoil for comfort or to make quick and accurate shots easier against threats, you need the 5.56.
Assuming the ammunition market hasn't gotten weird in response to the impending apocalypse, finding 7.62×39 ammo or 5.56 ammo is easy as pie. If you walk into a gun shop with a blindfold on, you'll find both types of ammo. (If you do, the clerk will think it's weird, so wear a blindfold and buy ammo from our site instead. Be sure to have an explanation for your wife when you blindly order 38 boxes of 22-calm ammo.).
Both rounds cost the same. But here's the problem: AR owners often cite extraction issues when firing a steel-case 5.56, but the AK's tolerances allow it to fire a steel-case 7.62 with little trouble. In short, if you choose the 7.62, you get the most out of every budget-friendly, steel-cased Russian ammunition available. You can't reload, it shoots a little dirty, and the bullets are magnetic, but you can save a lot of money with an AK!
The 5.56 provides slightly higher accuracy and lighter recoil. 7.62 not only provides more energy at impact, but also provides an opportunity to better utilize the cost-saving strength of steel. It's fiercely competitive, but it overlooks a crucial factor in the 5.56×45 vs. 7.62×39 debate: the rifle.
Vs. .223: Which Can I Shoot?
There are several rifles for 5.56 ammo, all capable of firing the same 223 Rem ammo. The most famous of these rifles has practically no mention. Accept the 5.56 and you'll have fun with the AR-15. It's infinitely customizable, as cheap or expensive as you want, and extremely reliable. Because Americans don't understand guns, they prefer rifles that aren't practical.
The AK-47 is relatively remotely unoptimized. It feels like Mikhail Kalashnikov is missing something, but besides what AK stands for, you could also put a bayonet on it or give it a weird scope mount. Alternatively, you can get the SKS instead, but this will never be a gun modder's dream rifle.
Still, A.K. Blessed with you can get a real workhorse for around $500, and you can abuse it before it even thinks to get in your way. And while this may sound biased, the AK is a very beautiful rifle. Walnut has a certain charm that polymers can never match.
If you're on the fence, try the AR-15 and AK-47. See which one is better, then decide if you prefer 5.56 or 7.62 with that alone.
