supersonic next step
I have been thinking (I know always bad) I am back on the supersonic air rifle thing again. What I am thinking is small bore rifle barrel to get the correct twist say .17. Use actual rifle bullets to get correct dynamics for supersonic flight. Then get Sean to make me a custom high flow valve. Possibly make it a large bore for maximum flow and then use a breach to taper it down to .17? What you think?

If you want to test “supersonic” with .177 Cal, I believe the stock “high Flow Valve” can provide you that speed.
