Do you know whats the difference between someone dumb and smart?
The smart person will admit they are wrong. It is not shameful to be wrong about something. actually after being provided proof that one is wrong it is a sign of great intelligence to admit it (and it is never too late).
Lately on the internet most people are hellbent on never giving in. I have no idea how this trend started that “wrong = bad” but its completely false. As far as i remember, it wasnt always like this. its pretty sad how dumbified the internet population has become.
Again, being wrong and admitting it is a sign of growth, be proud of it, not ashamed.
Now with this in mind, read my explanation and carefully consider the words within and your next move.
First thing’s first. What exactly is recoil?
Recoil happens because when a normal gun fires (that’s chemically propelled), the trigger hits the bullet, and the gunpoweder inside the bullet ignites creating an explosion. An explosion sends an equal force in every direction, thus propelling the bullet forward and the gun backwards. The force sending the gun backwards is what you feel as recoil.
Thus the bigger the bullet the more gunpowder needed the bigger the explosion the stronger the recoil
Now here’s another important note : EVERY single chemical propulsion is nothing more then a glorified explosion. It doesnt matter what it is, if its liquid helium inside a rocket, or gunpowder inside your bullet, or promethium inside the jet of your valkarie (40k only, prometheum doesnt exist in real life… yet) All of it, is a controlled explosion
Now in order for a gun like the boltgun to actually work, you need to do 1 of 3 things.
Scenario 1 : you make the bullets start their ignition inside the barrel, this results in slower rate of fire, because jet explosion is weaker then that of gunpowder ), it needs to wind up (Aka bullets leave the barrel slower). It is a weaker explosion but absolutely perfect for a constant thrust.
The bad side : due to the rocket staying longer in the barrel, it exerts too much heat on the gun, thus resulting in higher degradation of the barrel (and god forbid, heating up of the magazine resulting in you losing your arms)
also slower rate of fire.
Scenario 2 :
Make the gun expel the bullets with a spring (primitive and dumb sounding but it would work).
But again slow rate of fire because the bullets (or rockets, however you want to call them) need time to wind up and build up speed due to the weaker explosion a jet produces.
If you would fire the gun like this at the rate of fire of a normal boltgun, the bullets would hit eachother. But hey! At least this way you would literally have 0 recoil Yay for you!
Bad side : slow rate of fire and the more talented xenos will literally be able to see the bullets leaving the gun and starting to head in their direction which will mean they will dodge it.
Basically you will never be able to hit any Drucchi or Aeldari .
Scenario 3 :
(Now this is what the imperium chose)
We want high rate of fire, high velocity and deadly power. The only way to achieve this with your mini rockets is to encase them inside a normal bullet and give it the best of both worlds and make it first use gunpowder (or whatever magic powder the imperium uses) and then prometheum propulsion (or whatever magic liquid is inside those things).
First you trigger a gunpowder explosion, granting it 100% speed from the very first ignition and making you feel the might of the imperium of man in your arm as recoil, the now empty bullet cartridge that held the gunpowder and the rocket leaves the gun from the side, meanwhile the rocket leaves from the front of the barrel and ignites its fuel source at full speed increasing it to 150% and never slowing down now able to reach even the furthest of foes (as long as the rocket still has remaining fuel).
Immediately after the first cartridge and rocket leaves the gun, the boltgun can reload a 2nd bullet and fire that one off immediately giving you the ability to shower your foes with the might of the imperium of man.
If you want to see how fast a jet propulsion is alone without a gunpowder to give it the first kick, go to youtube and look up any rocket videos.
Now is that clear enough for you now?
And anyone else reading did i make any mistakes here? I couldnt possibly care less about guns, i just used logic and my knowledge of physics.
