The next variable to be changed was indeed the flyer thickness up to 2mm.
The projectile from that test did hit in one spot with minimal breakup, the other marks are from previous tests.
Unfortunately it hit on the very top and transferred a third of its energy off the damn plate:mad:



a simple LASER pointer will help you to aim the impact point on target. If feasible you can try out variable thickness to improve penetration. Sof iron will be a good option for coherent projectile as it has better resilience.

I did have one that I always used to use but the battery went dead that day so I was forced to try and sight it by eye

Found this new paper on truncated charge shapes. The addition of a thicker plate behind the cone allows for a slower forming (think a subtle push of the cone into its inverse jet) and sharper jet that has better properties than its original counterpart. It acts as sort of an explosive lens-version of a shape charge. Maybe even incorporating the design of a lens into the shape charge might allow for tighter compression and inversion of the cone. https://onlinelibrary.wiley.com/doi/10.1002/prep.202100162
