Birdie Bullets: 4.6x30mm vs. 5.7x28mm


To everyone except anti-gun people.

Now you see me

Did anyone miss me while I was away for just a shade under five years? Yes? No? Maybe? For a while now, I almost forgot about HubPages because of college, graduation and even finding a job.

And who can forget the Covid-19 pandemic?

So, what, exactly, is the point of a new bullet comparison blog, you wonder? Well, let's find out, shall we?

Dieting and Crack

To start off, when I talk about soda, I often compare the sugar content. Not only that, I compare the can or bottle or whatever the world it comes in. Hell, it could even come raw, for all I care.

The fact of the matter is, there's not much difference in guzzling down a can of Diet Coke or Coke Zero.

No, really. There isn't. I promise you.

How do I know this? Well, in a nutshell, I guzzled one can of each for a day and found ants on all my clothes the next day. Was I worried? Too bloody right, I was.

And it's the same thing with anything else of comparable roles:

Mercedes-Benz E-Class vs. BMW 5 Series. F-22 Raptor vs. Sukhoi Su-57. Glock 17 vs. Beretta M92. Knives vs. daggers. Urine vs. feces. The list can go on, folks, but let's not get carried away.

See what I mean folks? There's always something of comparable roles and it seems as if it's kinda pointless comparing anything to anything these days because there's really nothing much in the way to compare two soda drinks. Or is there?

They're both crack

They're both crack

You see, a soda requires chemicals (like all things, really and that includes you and me). Just add some sugar here and a little bit of this there and that there and something called "natural flavors", and you're pretty much ready to go.

And that brings me to our main topic, folks. Ammunition also requires all sorts of chemicals. Brass, for instance, is used on the cartridge that holds the propellant powder. Copper was (and still is) used for bullets to maintain the inner core while Gunnery Sergeant Hartman (R. Lee Ermey, Full Metal Jacket) was made of Gilding Metal, Cupronickel or Steel for armor penetration.

So then, you might be wondering to yourself: "when's he gonna start?" Hang on to your helmets, sunshines, cause I'm gettin' there!

Challenging the standards

Let's be honest. The 4.6x30mm is a relatively new bullet that aims to dethrone the legendary 5.7x28mm round. And so far, it's gotten quite useful in CQB and PDW roles. I'm also told that the Secret Service uses this bullet too.

This little bugger is quite the badger. The darn thing seems to have an uncanny ability to do more damage to soft tissue than the 5.7x28mm. The reason (and possibly the key) for this is its extremely diminutive size.

I'm sure all of you are familiar with the replacement of the legendary 7.62x39mm round, the 5.45x39mm used by the AK-74 type rifles used by the Russian Federation. Yes? No? Maybe? Whatever.

In any case, the 5.45 has this ability to "yaw" inside the body of a human in flight thus causing massive tissue damage. In layman's terms, the 5.45 is literally moving around inside the target's body while it's trying to find a way out. And the same principle applies to the 4.6..... Only more. Hell, this thing is so small, it has the same mass and center of gravity of a worm. Which only adds to the carnage.

And the MP-7 this thing was designed to be used on is just a breeze to carry around, believe you me.

By the way, has anyone seen firearms ballistics? Well, you maggots better start watching cause imma make you do 30 laps around my Marine Corps! Ready, move!

Sticking to the normal

Ah, the 5.7x28mm round. *sips cappuccino* THE standard when it comes to cute, cuddly, tiny but supersonic and armor penetrating ammo. I mean, who wouldn't want one of these kinds of bullets when you're in the middle of a heated battle and your life is at stake (and so's your client's and teammates' lives, for that matter)?

This bullet has proven itself time and time and time again and has flying colors for armor penetration. There's very little that can match it (well, only one other round, actually).

Thing is, though, that this bullet fails in one category and one category only compared to the 4.6 and that's it's size. It's just a wee bit bigger and that means it's got a tad bit more weight and less ammo to carry.

Plus, let's not forget the P90 this thing was designed for is, for lack of a better word, too long. I mean seriously. I've held an MP-7 and a P90 and God above, the H&K is more compact.

Also, the P90 ejects spent cartridges DOWNWARDS which means, if you're in a vehicle and want to lay massive, overwhelming firepower (or are simply spraying and praying), you're going to fry your sausage. And that's gonna hurt.

Well, naturally, you're in combat so that fact alone is gonna hurt! Scream now!

The Chart



2.0 g (31 gr) Copper-plated steel bullet AP (CPS Black Tip")

735 m/s (2,410 ft/s)


31 gr. (2.0 g) SS190 AP FMJ

716 m/s (2,350 ft/s)

Bugger me!


Make your choice


Now, to end this comparison, folks, I have decided to say that, regardless of what firearm and ammo type you choose, you can keep the enemy's heads down simply by spraying and praying.

I mean, the P90 goes at 900 rpm, for crying out loud. And though it has only a 50 round top-mounted mag, a four-man fire team can keep the enemy terrified while rushing them simply by alternating fire.

The MP-7 isn't a bad choice either as it fires 950 rpm and is the same length as a P90 even with a suppressor on and thus makes it better for stealthy or black operations.

Of course, this applies to combat at 100 or so meters as the spray and pray effect will disappear after 100 meters. More or less. Anything above 300 meters, and you might as well go for a dedicated assault or sniper rifle. But anyhow...

Which would I choose? Why, I'd choose both, duh.
