THATS COOL! I just went to Targets and wanted to buy one of those tanks. My question is, what type of fitting did you use to put the low pressure helium into a high pressure airgun cylinder?
Cool experiment for grins & gigglesBut imho that regulator really held back the Gladius quite a bit. I'd love to see the results of using helium with an unreg'd tube & the gun set at full power.
Uh......275bar on the Gladius? Arent those a 200bar rating?
Thanks for posting this info. I have been curious about using helium for a while so it is great to read to real world data.I agree with Mod90 that the regulator probably held back the power but the same is true when it was being run on hpa. 150bar of helium compared to 150 bar of air is a good experiment. In theory though, helium should deliver an even greater increase in energy compared to air in an unregulated gun.They have a chart on the Extreme Big Bores website which shows how their PCP rifles perform on HPA vs helium. I remember that one of their rifles output 450ft lb on HPA which shot up to 1450ft lb on helium. If you have the time, I would love to see the same experiment with the reg removed.I am also interested to know if, with the reg, the bulldog could be tuned down to deliver a greater number of shots on helium with the same energy as on air. Usually helium escapes faster than air delivering fewer shots but with the reg, I'm not sure what happens. How many shots did you get at double the energy?

Arent those a 200bar rating?Yes but i was told from the place that i bought the regulator from that once you install the regulator that you can over fill the reservoir because it then takes the pressure off of the valving system. In fact they told me i could fill to 300 bar but i just wanted a bit of margin of error.
Did you have to do any conversion to your gun? Or was it just a straight fill
That's crazy! I really would have been cool, if you had some 25 grain monsters to try
