This is isn't calling any specific person out b/c I've seen this comment multiple times in just the last week, but why does it seem like the average airgunner views high fill pressures as a pro? 

From my perspective, I'm not a fan. I've seen what high pressure air does to male foster fittings, even high quality ones. It's harder on every component that is exposed to it, from air source to trigger pull. 

And yeah we don't have to fill that high but what's the point of the gun being capable of filling that high if we have enough wisdom to not stress all the parts and so we dont fill that high. 

Shot count from a full tank goes down with higher fill pressures too. 

I smile to myself every time I get into any kind of high volume shooting with my USFT and it's 1450psi fill pressure. The new electronic gun from SHOT show piqued my interest when I heard the detail of low reg pressure. 
 
More air compressed into the tank it doesn't really put more stress on anything else but the bottle and the regulator most guns that are filled to that use a regulator to knock the pressure down right off the bat to like a 150 bar if the reg were to fail then yes the rest of the gun would see the 300 bar seems like every one is on the more pressure more power kick that and slugs every one wants to shoot slugs it also seems

You asked why the average airgunner sees high fill pressures as a pro, but I have never poled airgunners so I can't speak to that. I can tell you why I like high fill pressures though. More shots. I don't care what other people fill their guns to as it isn't my business. I neither condemn small air people nor praise them. But what you are saying is that you are wise because you don't fill to recommended max pressure the mfg has recommended. In your view that has to make everyone who does fill (all the way) airguns rated to 300 unwise and you've said as much. Airgun manufacturers raised the bar, so to speak, because they saw the benefit to airgunners in every way. If you are finding fittings that are harmed by higher psi you may want to address that with the manufacturers as most of these fittings are set to withstand many multiples of a 300 bar psi stress point. I have never had a fitting or any other component on a well made AG that took 300 bar, suffer any damage from repeated fills for years.

I have an Avenger and a couple FXs. The Avenger is 300 bar and FX 250. Quite a few Eastern European guns can fill to 300 bar. FX is on the way to 300. If components are good enough, 300 is no worse than 250. Cheap guns don’t worry about longevity or reliability, they play the specifications game. Certain major brand always prints high FPS numbers on their boxes even though supersonic pellets are mostly useless. High end brands are much more cautious in their claims. In case of FX, new models are 300-bar ready. You only need to change two things: the fill gauge and the bottle. 
There is no need to reach the spec pressure when playing at home and it is good for your gun. But if you go hunting and don’t bring your big tank, the ability to fill 50-bar higher is pure happiness.

Exact words were why does it SEEM like that after I've seen multiple comments where as much was said. No, I haven't polled either. 

Maybe you haven't shot enough to see the effects on male fosters. Male foster deformation WILL happen eventually, higher pressures only accelerate that. It's in the form of tiny indents I'm the locking ring from the balls inside the female. I've seen it on some pretty high end airguns. 

You've also got the effects on orings. You know how they're flattened when they've been in a gun a while? Logical assumption is the air pressure they're holding back is what's flattening them. More pressure = flat orings = leaks sooner. 

Yes manufacturers are rating them that high, but they're also putting 140, 150, 160 on speedometers in cars. If I run a car to its limits on a regular basis it is going to shorten its life. 

If a guy wants to fill that high that's fine with me. Their gun their choice. I was just pointing out that the manufacturers toting it as a feature (and then airgunners also thinking it's a good thing) is kinda like the print on the boxes of cheap springers at Walmart with speeds listed as 1000 fps!!!

I've been shooting pcp's since the 1990's.. Been airgunning since the early 1970's.. Just fill low and leave supposed dangerous "recommended max fill pressure" followers be.

I'm not really onboard with high fill pressures yet. Higher operating pressure will equate to more power potential. In some cases, this would be desired, maybe even needed. I don't have that need or desire. Volume of charge does not increase linearly with more pressure. The amount of volume added to the recepticle per bar goes down more and more the higher you go. I like filling my guns a bit under their rating typically. 200 bar guns often around 180-190, 250 around 220-230. They just operate more consistently like this. Regulated or unregulated.

Nothing wrong with 300 bar fill guns. If the gun is rated for that pressure. Then go ahead. 300 bar will get you more shot per fill. It also allow for higher reg pressure. If you gun is only 250 bar and your reg is set to 200 bar. Then you only get 50 bars to use. People think having 300 bar will be too much for the gun to handle and it will break sooner. That is not true. Having a 250 vs 300 the gun is already under a lot of pressures. It wouldn't make the gun fail any time soon cause one is fill to 50 bar higher.
