1000v 360j capacitor bank
switch: auto relay with bigger contacts
projectile: lead slugs with plastic tails

shot through 22 gauge steel

From the muzzle flash it looks like the discharge time is too long and I'm losing a lot of efficiency, so I tried shooting a 17 grain (estimated) slug instead of 6 grain, and I guess the cartridge couldn't take the pressure...
This is what happened to the capillary tube and the cartridge was jammed in the breech, I'm surprised the barrel didn't explode.

Here's a video of an old chamber design.
