Portable Coilgun

Q: Will a smaller projectile result in better efficiency? A: No, a smaller projectile won’t magnetically couple with the coil as well as a larger projectile will, and won’t absorb as much energy. So a small projectile will actually carry much less energy and probably even travel at a lower speed. Q: Will rifling in the barrel improve accuracy? A: No- Rifling depends on the bullet expanding within the barrel, which doesn’t happen with a magnetically propelled projectile at these speeds. Q: Will you sell it? A: You can buy my latest coilgun at Q: Will you post plans? A: I can’t share plans, but I’m willing to point you in the right direction. It’s not that hard- I started this project with zero experience with electronics. It takes more patience than anything else. Q: Will multiple coil stages improve power/efficiency? A: Yes! I only have one stage on this design for the sake of simplicity. Q: You should shoot it into some meat! A: That’s a waste of a potential sandwich Q:
