What happens if you fill the fx impact to 300bars? I know the bottle will hold but what about those burst screws on the gun?
Fill a fx impact with 300bars?

Yes there is two, one behind the bottle and one behind the handle..
to get more shots pr fill
i havent tryed it, i was just thinking why they don`t fill to 300, my compatition rifles all fill to 300 bars

Your other rifles were designed for that 300bar fill where as the Impact wasn't. Idk I own 300bar fill guns and never fill over 250bar.

There’s also the fact that the factory pre regulator gage won’t handle those higher pressures. My hatsan bully is a 3600 psi max fill, but it is most accurate with only a 3200 fill. So the higher fill pressure could affect your accuracy, maybe.

Aloha,
I'm with Bob, don't do it. I don't think the internals will handle the pressure. But I you want to experiment (make a video) stand far away and fill to 300 bar then us impact owners will know what happens if you fill to 300 bar.

Ha ha i was just wondering why any havent tryed it yet. I know i just can put a bigger bottle on, or two, but it just seems like a easy way to get more shot count pr fill if it worked. The worst thing that can happen is a o-ring burst

I had an FX Impact Gen 1 (sold it) with an after-market bottle that was capable of holding 300 bar. I filled it to 300 bar and it seemed to be just fine. I wouldn't try that with a factory FX bottle though.

Also, the amount of shots gained from 250 to 300 bar is not linear. So although it would appear that shooting from 300 down to say 150, compared to shooting from 250 down to 150 would be 50% more, its just not true. It obviously has to do with the physics of compressed gasses at very high pressures. One past approx. 250 bar, the amount of energy per additional bar of compression decreases due to the air molecules closeness to each other (in layman's terms). You may only get 20% more shots, plus stress your system more than is necessary.
Additionally, duro 70 or 75 o-rings are really only capable of approx. 250 bar for extended periods without extruding. This is why 90 duro o-rings and gaskets are used in systems (like SCBA tank valve o-rings) where the pressure can be at 310 bar for extended periods of time... So the o-rings in the bottle fitting, and all the O-rings and internal parts that see bottle pressure on the high side of the regulator are suspect.
Bottom line: The juice isn't worth the squeeze...
