Check out this video of the new 95 cal. The slugs are HUGE!

2500gr. At 830 fps, around 4000 FPE

.95 cal, is between 5 (.977") and 6 bore (.920).
4 Bore, is .1052".
I wonder what it would do on Helium?

It runs pretty high pressure, so likely you'd have to do a mix of helium and air. If you can find it on the internet it must be true: https://www.tapatalk.com/groups/yellow/ ... t8056.html
from this, a pure helium fill would give 50% increase in power, but helium is only "packaged" at about 3000 psi and this sucker takes 6000 psi. So you'd have to do a fill to 3000 psi with helium, then top-up pressurize the tank to 6000 psi with air which maybe would mean 25% increase in power (assuming half and half mas mixture) ... just a wild guestimate on my part. But it does open the door to experimenting because any PCP can run a He/air mixture. Party City time.... ?

I need to have my education on the topic updated.

In a post regarding a 2240 PCP conversion. CO2 at 850 PSI was producing a faster pellet than Air at 850 PSI (PCP). It was explained that CO2 is denser/heavier than air and so it has more energy than compressed air. (At the same pressure)

Helium is less dense/lighter than air. Would it not have less energy?

No that post is backwards...That's one reason to shoot regulated HPA in a CO2 gun, you get more power (or greater fps) at the same pressure and of course its not temperature sensitive (regulated 800 psi).

So a less dense, lighter gas at the same pressure will produce more energy, a faster projectile.

Using helium, a very finite resource, would be wasteful.
There are other light gases which aren't so essential to many industries and in short supply. Hydrogen being one that comes to mind.

There are already helium 'air' rifles. "Mr. Hollowpoint" was testing one in 8 bore (.835") a bunch of years ago.
These are specially made rifles. I am assuming they need much heavier hammers and much larger ports.
Looked like an AEA rifle?

Not explosive if you don't introduce oxygen and far cheaper even now before vehicle adoption.
Once we have an infrastructure it could be as close as the gas station.

HHO - hydrogen gas makes a hot burning torch for cutting or welding.

Biggest shift will be that you have to purge a gun with nitrogen and also make sure there are no petroleum lubricants used.
Standard lubricant procedure for oxygen tanks, the nitrogen purge is just to make sure you aren't ever over 5% oxygen.
