Hmmmm, I’m thinking of a 3 or 4 stage coil gun, compressed air to get the copper slug moving and I’m thinking a 200 grain slug moving at say 3,000 ft/second. No powder, no bang very little noise. Just the crack of the bullet.
Now if you could spin the bullet prior to launch so the bullet is gyroscopicly stable then you would really have something.
No gunpowder?
What would the batfe do?
They don’t get involved with non gunpowder projectile weapons do they?
