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

A .45 jacket soldered into half inch pipe with 4.5 grams of melt cast ETN.

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

Very little of what video is coming out of that conflict is exactly what it appears or is described as.

I note in one video segment, someone is just walking along next to the "death ray" and just KEEPS WALKING NORMALY?! I assure you, IRL someone in that position would hit the dirt or go into a higher gear, be it away from kaboom or towards his squad mates smoking remains, not just keep plodding.

From video quality, could be CG animation.

From detail level visible, even if real, could equally likely be Ukrainians getting hit. I've found several videos where Uk propagandists changed titles on some RF drone video of their guys getting whomped and claimed "glorious victory over the evil moskals"! Easy to do when they're carrying same weapons, wearing pretty much the same gear and at least initially were operating very similar vehicles.

Obvious next step is test with a truncated 90° cone primary liner and a proportionally designed disc as secondary liner sitting on top-

A stupid simple bit of machining to accomplish that claimed 70+% increase in depth.

You are absolutely correct. I belive both the title and the level of the comments below the video have one common cause.

It's posted by The Sun ! My expectancies from tabloids are pretty low ;)
