Superb!

Interesting to see the effects of multiple ignition points, you can clearly see the difference - Bravo!

Also, love those Brenneke slugs... that barrel needs to go on ThorJack too ;)

thank you
For Thorjack, I would need a gun metal!
And 19mm internal, it is difficult to find ...

For ignition tests, I've done a lot, I have videos!

I used PVC pipe as a barrel for hybrids up to 15x:

The heavy duty stuff, I believe what the Americans call Schedule 40 - roughly 1" outside diameter, 0.75" inside.

It works great :D

Looking forward to seeing them :)
