Always loved the concept.
I remember when they came out. I was surprised they worked but they did.
I can’t see any advantage excepy maybe the guns would be cheaper to make.
Those rounds would be ideal for.a rapid fire weapon like a machine gun.
Does anyone remember the Dardick Revolver? It fired trounds.
I have never seen one but recall reading about it.
No recoil
No eject phase, cylic rate doubled, at least.
Quiet
Used with a suppressor I’d say very interesting potential for SF units doing DA work.
So would possession of a Gyrojet by a felon still be considered possession of a firearm?
As a high school grad, I worked for MB Associates, who had produced the gyro-rocket, gyro-gun, etc., for several years before going to college. Many were wall displayed among other products in the company’s buildings which were located on a former Nike-Hercules missile site in the foothills between Oakland and Walnut Creek, CA.
Robert Mainhardt was the president and his partner, Arthur Biehl had moved on or passed away.
The same principle of the gyro-rocket was used to produce the spin-stabilized flare that were or maybe still are the standard issue for U.S. aviators. They also produced the warheads for the LAW and TOW missiles used by the Army, chaff dispenser pods and chaff for aircraft, etc. A very interesting place to work but college lured me away...
I had at one time toyed with the idea of making a bullet with a central cavity and a small opening at the rear. The idea was that the cavity would fill with high pressure gas while the round was traveling down the bore, and then after the round cleared the barrel the gas would be expelled from the small rear opening to further accelerate the round.
But it was dumb for at least three reasons:
First of all, if the cavity inside the bullet was truly pressurized to roughly the same pressure as inside the bore, any conventional round would instantly rupture when exiting the barrel.
Secondly, even if somehow the round could be make of stern enough stuff to contain the pressure, having any kind of additional force vector acting on the round while in flight is bound to degrade accuracy.
Thirdly, any gas entering the round while it’s inside the bore is not creating pressure behind the round, therefore whatever boost you could gain after the round leaves the barrel, was first lost while the round was inside the barrel. The absolute best you could do is break even.
Thinking things through can save a lot of wasted time, effort and expense. On the other hand, Youtube would be a far less interesting place if everyone thought things through before trying.
Out of curiosity, I looked around to see what a Gyrojet round would cost.
I found ONE for sale on the Gunbroker site.
$600.00
