I mean Gyro Jet Bullets that are out on normal shell casings/primer/propellant rounds.
Any reason why we are not doing it?
Any legal roadblocks?
manufacturing cost for one thing.
gun control act of 1968 for another.
But wasn’t the ammo under 1/4 of an ounce and there for not a DD?
rule is not in ounces for rocket with explosive ordinance. is it diameter.
rule was 1/2 inch in diameter
So they came out with a .49
so .gov changed the rules to
1/4 inch in diameter
Even in 68 the projectiles were cost prohibitive.
The were epically shitty for accuracy too, they claimed them to be more accurate. When independently studied they were lucky to hit at 30 MOA…
I think the main problem was the idea of “rocket bullets” sounded better than it was.
The gyrojet wasn’t a firearm so much as a launching platform for mini rocket bullets. When fired, if somebody put their hand in front of the barrel that could actually prevent the rocket bullet from leaving the weapon platform.
Then there is the problem that a rocket bullet, even as it gains steam, just isn’t going to be as accurate as traditional ammunition.
There was also concern that to make a gyrojet “gun” all you needed was a tube and a battery and some wires. At least that’s what I read.
Of course here we are in the 21st century with 3d printers…

Gyrojets were just plain impractical. Cool idea, just didn’t work.
Terrible accuracy.
There are some excellent vids on youtube where they discuss why these sucked and why the company went out of business.
But you do get the idea of why I proposing, marrying the Gyro jet into a bullet an putting said bullet in the traditional cartridge format.
I don’t think you understand how the gyrojet operated. You could never make one with a traditional cartridge design, for starters there isn’t a chamber. And you don’t have a barrel so much as a launch ramp.
The gyrojet round was basically nothing more than a metallic bottle rocket that could eventually achieve a lethal velocity. The firearm itself was basically a glamorized coke bottle with a pistol grip from which you could launch the metallic bottle rocket.
If it was cost effective, somebody (and probably everybody) would still make this round simply for all the collectors out there who have an original gyrojet but don’t fire it because existing rounds go for $75 to $100 a round. So obviously there is no market there because making mini “rocket bullets” is probably a very expensive thing to do and likely to be severely regulated along the same lines as hobby rocket engines which were given a “one meter per second” speed limit.
Even if you took away those considerations and offered a “retro” gyrojet firearm complete with ammo, it would still be a novelty that most people would ignore for the same reasons it was ignored when it first came out. A few people bought the James Bond future gun, but when most people discovered it’s severe limitations, it became irrelevant.
If you need another example, just look at the Voere VEC-91 “caseless” rifle. It was an actual firearm, that was extremely well made in Austria. But it had an electronic ignition system and fired caseless ammo so it was mostly ignored and forgotten.
And that was a rifle that was actually pretty accurate and reliable.
I’m sure in 1988 or 87 the G11 looked highspeed but now it looks like a brick zack morris phone. A product in a time when it could only have existed.
With things like the G11, you really have to consider development for production.
Keep in mind during development this is what the UMP looked like.
You can kind of see the UMP in there, but if that is what they actually gave us, we’d have really, really balked.
Oh I know, but I was taking about making bullet that are like gyrojet rounds, filled with solid propellant, but activated upon being fired from a standard cartridge.
There would be no need for a standard cartridge, it would be super flourious and pointless.
But wouldn’t it launch the bullet to speed, after which the rocket would activate make it go even faster?
How fast do you think is going to happen?
Let’s say you don’t think your AR shoots your 55 grains fast enough at about 3200 fps.
You want a flatter trajectory.
You get an old 225 Winchester and let them rip at 3500 fps.
Still not fast enough for you.
So your new 22-250 goes over 3700 fps.
You want faster still. You start looking into 224-06, WSM, etc. and decide none are going to cut it for you.
For starters, get a year of calc and physics and some P Chem under your belt.
What are you possibly going to do to that bullet that will increase its velocity after it leaves the barrel?
You have limited capacity in the projectile.
Your projectile will lose mass as it burns propellant.
How does the propellant increase velocity without jacking up your trajectory/accuracy.
What is the ignition system for the propellant?
At what range does it ignite?
How long to get added velocity maxed out?
You will pretty much get back to where you started.
More brass capacity for more powder to go off in the chamber is where you will best get your velocity increases.
And there is a practical limit to that velocity.
I would be most likely the heat from the burning of the propellant in the primary ignition.
What is the fastest round in general and the fastest round an AR can take?
No it wont. Thrust would have to exceed the rate, which is not going to happen.
If your plan is to ignite after decreased rate you would lose all stability.
Terrible idea.
Any of them will be faster that a Gyrojet, the originals .49 only achieved Mach 1.3. Would be substantially worse in .223
Ever feel like you were born too early?
Because the tech of the current age is sub par.
