Job’s a good’un.
I’ve finished my new design. I’m getting just over 1000fps from 3000psi to 2000psi (extensive testing has shown that the 21-grain Bisley Magnums in .22 give the tightest groups between 950fps and 1000fps), so that bit’s fine. The best bit…interchangable heads. Going from a 6mm bore to a 1.5mm bore the ftlb energy comes in at around 11. Switching heads is a simple matter of pullling one out (with fingers) and popping the other in. There’s a nylon sleeve in there to give just enough friction to hold the head securely.
Only of interest to UK gunners of course. Legal head for use in the UK, 6mm head for use in countries that permit it. 😉
I’m very chuffed with meself. 😀
