To a point. Once the magnetic field gets to a certain strength, the projectile magnetically saturates and the only way to really get more kinetic energy into it is to make the barrel longer. If they can demonstrate this firing the equivalent to a .22LR, it would be really amazing.
Edit: They claim "up to" 75 ft-lbs muzzle energy, which is in the realm of .22LR. Check out this chart: https://www.mcarbo.com/22LR-Ballistics-Chart https://www.mcarbo.com/22LR-Ballistics-Chart
- graderjs 5y agoAwesome, this is why I come to HN, for comments like this; to learn. (aside from the dopamine hits from posting...)
- amluto 5y agoDoesn’t saturation of the projectile mean that further increases in field strength increase acceleration roughly linearly instead of quadratically?
- GravitasFailure 5y agoYes, but it also means an already inefficient system takes an absolute nosedive in efficiency.
