9.5MM Air rifle, bolt action

[Gnarp]

Hello

Building a gun that shoots 9.5mm steel balls

Gun spec:
40BAR @ 171m/s = 73j. Trying to hit 100+ Joules.
Ammo: 9.5mm 5g
10mm@49cm barrel
QEV: qe-03
CO2 tank 605ml
12v solenoid
Arduino controlling the pilot.
Removable bolt.
To do:
Longer barrel, 75cm
Buy 10mm steel balls.
Round the bolt for better flow and drill out the the coupling after the co2 tank for better flow.
Make less deadspace in the pilot and in the breach.
Need some tuning and stronger spring behind the qev piston!, it dumps to much air.
The solenoid is set to 10ms for now!
Longer barrel for the final design and 5 ball spring loaded magazine.
