I'm not at all sold on the Orgus hype. The theory only just works in TK Hop Twist barrels and there's a vortex there. What Orgus cannot get around is the eff ay see tee FACT that the wider the barrel is, the wider the exit cone. End of. It may well be possible under certain conditions with certain BB's to get positive results, but snap firing under skirmish conditions, even well aimed fire into uncertain air conditions, humidity, barometric pressure, colon disposition, etc... I just don't see it.
But thanks for the link - at twenty five bar for a 1 point sling, i'll make me own
