I think that:
“but consider if that part of the passage were placed inside the grooves of the rifling and offset enough to allow passage of the bullet”
and
“oriented such that it opposed gasses escaping from the weapon”
are conflicting specification requirements.
sounds to me like a recipe for danger- the gasses NOT being allowed to escape could cause the barrel to explode
I have seen and read about Tesla’s device- he was SUCH an amazing man
Many of his inventions are tought to be hidden away by the govt (if you believe in conspiracy like that)
He invented a death ray and a tiny oscillation device that could bring down buildings. One day his experiment went wrong and when the police broke in to find out why the building was shaking itself to pieces they found him trying to destroy it with a sledge hammer because he could not turn it off.
I would have loved to have seen that...
