Looks like a muzzle velocity in the 500 fps range.

Would recoil be negated at all with this type of propulsion? I understand you're still throwing mass downrange and physics still apply but....and I could be wrong....it seems like (relative to instant explosion of current powder based rounds) the projectile would take a bit longer to reach max speed out of the barrel. Either way Ill take 5. |

It looks to me like his biggest flaw is that his projectile is rediculously large for his power source.
The whole point of magnetic propulsion was supposed to be light-weight/ ludicrous-speed. |

These things will get smaller over time
The problem with every one that I have seen built is that it is always a heavy projectile going slow. What they should be making is a light projectile that goes fast. |

The charging power value and red to green light made me wonder if something similiar will be implemented in a military gun someday. I could see waiting a ridiculously long time with a nearly drained battery, hoping it charges quick enough to get off a shot. Also brings up other ideas, like plugging into a non-portable power block in a fixed position, or into a vehicle outlet. |
