Hey, Just started the machining of my hybrid.
It had an 18mm ID. 1/4" threads at the rear and 1/2" threads at the front.
I know the end is flat, however the through hole is only 12mm and is about 50mm deep

I doubt I will take it even close to 200X
Maybe 50X regularly and go from there.
I have a .22 rifled barrel I will be shooting pellets from, Looking for some BIG numbers

Looking good there!
Did you cut those threads with the lathe or with a tap?
Did you figure out your fueling system yet?

Thanks guys, I cut the threads using taps but was really surprised how clean the threads are
Im going to use the manometric method.
On the rear of the chamber there will only be a (Rated) ball valve and a male quick connect.
Propane will be coming from a big 5kg tank. A famale quick connect and gauge will on a tee connected to the propane hose.
For air i will be using my air rifle pump

Get yourself some heavy slug style pellets, if you use diablos you'll just be firing lead shrapnel
