Power should always be adjusted gradually, with the assistance of a chronograph so you have a reference of the velocity of the projectiles. The power adjusting screw has no stop, so theoretically, you could unscrew it out – don’t do that. The maximum recommended turns are two (720°). If you absolutely want to reach absurd power levels, then you can make it two and a half turns total, but take care to refill the gun when the fill pressure drops to 220 BAR at least.
