What would be the real ticket is to make a larger version of one of these rocket units that was about 0.700" diameter with a single centered rocket nozzle with no primer igniter but the propellant exposed and then coat it with a high temp silicon jacket to take it up to 0.729" diameter and then load it in a 12ga. shotgun shell with no wads between the powder charge and the base with the rocket nozzle and then fire it out of a fully rifled shotgun barrel with the conventional shotgun shell powder charge providing the initial acceleration out the end of the muzzle with the rifling giving it spin stabilization and the shot-shell powder charge serving to ignite the rocket motor so that the rocket motor kicks in after the rocket slug leaves the muzzle and accelerates the projectile further beyond the velocity that can be safely achieved without going over shotgun pressure limits. I'm envisioning a rocket slug that instead of being a 1-oz. slug at 1,600-fps-ish muzzle velocity the rocket motors additional acceleration beyond the standard muzzle velocity boosts that up to a 1-oz plus slug achieving 2,200-fps plus peak velocity due to the additional boost of the rocket motor inside the hollow slug. Basically a smaller version of rocket assisted artillery rounds !!!

As I commented on the video. I got my patreon moneys worth from this one.

Super Awesome that you guys got to shoot one of these!

Thank you Sean, if you're on here! That was absolutely fascinating.

Fascinating and educational video. Thank you so much for posting this and sharing it with us.

First thing, Hey SomeGuyInSandy!!.. Jeff, It's really supportive in more ways than one, The firearms community has been under attack for many years, However, The example is shown here. The Gyrojet is an rare exotic system that really was thought outside the box, Jet propulsion was in its heyday during the time period that this was tried. It's history we witness today only through the generosity that the owner of these museum pieces allowed us to experience and enjoy. although your show isn't like "Forgotten Weapons" or similar channels, Your show shows the inside view of the science of Ballistic characteristics in a format that is funny to watch, also enjoyable to view because of the quirkiness. anyway, Thanks to the community we can watch subjects like this without the "Hollywood Documentary" opinion's in a real time format.

Definitely a once in a lifetime! The owner made the right choice by picking you to do the video!

Fascinating video. I remember seeing a few of these and the ammo for sale at gunshows years ago when I was a kid, if only... Does anyone know what the propellant is? Makes me want to see if I could make something that would work. The plug in the back of the ammo wouldn't be difficult with modern machining techniques. If there was enough demand I think the plug could be made using MIM but would be expensive.

Great video and really fascinating guns. Thank you for making this video possible Sean.

I wanted one of these pistols so bad but my dad wouldn't let me buy one . I still love my Dad
