This gun fills to 300 BAR!!!!!!!!
My Impact only fills to 250? Why?
Like said different materials used and wall thicknesses.
Just because a gun can fill to 300 bar doesn't mean it's necessary. My .30 Flex is capable of 300 bar fills when regulated and 250 bar when unregulated. But I have it tuned right now for 21 shots at 85fpe unregulated with the string starting at 2700psi which is 186 bar. I'm debating on tuning it for more shots at a higher pressure but it's nice having such a low fill pressure.
Regulated filling to 300bar doesn't gain you much really if you think about it. Sure more shots per fill technically but it's over a wider range of air so your not saving anymore air you just technically don't need to refill as fast. Now if you don't have your tank with you when shooting I can see the issue but if not there's no real benefit
Pressure vessel design calculations require thicker wall thickness and that drives up weight and cost. I used to design pressure vessels for power generation, and the hoop stress calculations are the same. This is why a long skinny tube gun is cheaper than a bottle gun
