Just had a thought,very dangerous, is there a shroud extention so one could go to a 500mm liner? Add 120mm a liner of choice and in my case a Huma dual port, mabe in the $250 range. Another though, how about a 500mm shroud?
I bet something could be 3d printed....
I am ordering a 500mm shroud for mine as my rifle recently took a fall from where I hung it (by the bipod feet, the feet came off!)
I've been itching to dial the gun in for some light weight slugs in .22
I had a .22 500mm barrel before (sold with my other crown) and didn't even fully dial it in, and was seeing 50fpe from it. Max on 380 is around 33 or so I think
My 700mm is tuned to about 62fpe, can go higher, just shoots 36gr slugs best there.
I only shoot 18.13 gr pellets thru the 380, nothing heavier. I have run the 380 on my slug tune, and I think it picked up maybe 10 or 15 fps? Lol. Super loud.

Wow. 62 FPE! I am impressed. I’m gonna have to go look at my 700mm tune again![]()

It peaked at 65. My reg gauge says 155 bar, but factory gauges have been known to be off. I use an additional 7gm hammer weight, and massaged the barrel port/pellet probe to streamline airflow. I run the gun on 30 cal transfer port, and bellmouthed the inlet of the barrel port to match the .30 opening![]()

That's why mine was outputting more fpe. More weight and more pressure will get it around 75fpe
