We were able to make the impossible happen, test out two rare Gyrojet rocket guns. Remarkably, instead of just taking one or two shots, we were able to take 4 shots. We were able to learn a lot with these limited test still.

  1. I wonder if it would be possible to create modern reproductions of these rounds to enable further exploration into this fascinating part of firearm history. I imagine they would be much easier to machine with modern processes, though likely not much more economically I'd imagine. However, if it were possible to obtain new rockets, further testing could be achieved, and comparisons could be made with the data from rounds that have aged since original manufacture. You would likely be able to achieve much more predicable angles for the nozzles, and consistent burn times in the propellant. I imagine it would still cost an arm and a leg to make, but could be worth it if you just happen to have a machine shop on hand haha

  2. Wow that was really nice of the owner. Is it even possible to get ammunition for them anymore? If not you all just increased the value of the remaining ammunition significantly. What a very interesting concept that was pretty much doomed to fail from the get go. Maybe someday we will be able to make consistent rocket propelled ammunition.

  3. I tell you what if they made guns like these now abd made them better military would have way better chance of being more "stealthy"

  4. Ed Kline used to make his own version of rocket bullets in the late 1970s, made his own gun which would fire multiple rounds in automatic mode, and he put some kind of explosive in the rounds. I've no idea how fast the bullets he made would go or how much damage they would do as just a bullet. But, I know of a test where he went out into the desert and hit a broken down VW with one round and sent the engine flying through the air. He had spent a year or more making the ammo he ended up using in something like 30 minutes, but that 30 minutes did get him in trouble.

    He ended up having the FBI pick him up, take his gun, ammo, and explosives away. They didn't end up charging him with anything, but they gave him stern warnings about not making any further explosive bullets of explosive anything, or making any full automatic weapons. I think their biggest issue with him was the explosive he was making and he was also under some kind of a legal requirement to not tell anyone how to make that explosive or make a fully automatic weapon, which he signed as part of his not being charged with a crime.

    Considering he almost blew his hand off one time, it was probably very good this stopped him from making any further home made explosive bullets because it was fun to go out in the desert and blow stuff up.

    I watched him make one of the bullets and it was really very intense, a lot of detailed work which had to be done very precisely, thus it was costly and time consuming to make even one bullet, which considering how fast they get used up makes them ridiculously impractical.

  5. Cellulose is highly corrosive in time. I had sheets of cellulose (kinda like you'd have sheets of plexy today) and they degraded in time. Became crumbly and eventually broke to bits. Left them where they were standing, they emanated a specific smell and later i figured out why there was so much rust on a metal shelf nearby, why the jacket i had on a coat hanger also near by was off color etc (for those wondering, a work in progress house i own).

    Anyways, figured that the cellulose was degassing something, put it in a metal bucket (meant to hold acid etch primer in a previous life) and then left it for 5 months. Came back to it a week or so ago, the thing was rusted on the outside and when i picked it up, the whole bucket came apart and the cellulose bits fell off on the ground.

    Highly corrosive. And highly useful to start fires. One fist of the stuff is enough to light a damp log fire, which is what i've been using the stuff for.

    All this story is to express the amazement that these shots, 50 years later, haven't fallen apart in the gun at prime point splashing metal all over the place.
