Nice work on the extension. What is the thread size?
Can you directly test the velocity difference between 600mm and 700mm with no other changes? I'd be interested to see how much speed is added with the longer barrel.
Thanks,
Rusty
A friend of mine make it in about 1 hour without the draw, and works perfectly. 700 mm is what I like, and this simple extension save me a few coins on a new barrel

I’m interest in buying one of those extension if your friend is willing to make it. Please pm the price.
I watched Matt's excellent slug liner video today, and it changed my plans for the two 700mm liners I have. I had planned to cut one off at each end, to try with and without the choke at 600mm. In the video, he talked about chokes and the fact that some barrels don't need them. He stated with 100% certainty that the STX barrel will not perform well without a choke, so he probably saved me $110. I cut one of at the breech end today, and opened up the rifling as carefully as I could to match how the factory breech end fits. I'll plan to keep the other liner full length, and find a way to make an extension.
Thanks,
Rusty
