It is after all a test setup so why not ;) Do you ever plan on mounting a proper stock and trigger to fire it from the shoulder?

I also had an idea about making a hybrid rifle soon after I bought a strong stainless steel 8mm barrel, but the idea of cartridge it'a really interesting, if a relatively small cartridge (10cm of 3/8 copper) is strong enough to accelerate a 8mm dia steel bb to a average muzzle speed of 200m/s, I'd make it. Are you really going to make that stock? That would be very cool.

Make cartridges that's great!
But for safety, you must fill the cartridges locally ...

yap, I know, I even have 1 ml syringes :lol:
