Just for fun i saw what kind of power the impact makes in .25 at 100 bar on the reg. 64fpe with heavies, turned the valve adjuster down to the 4th line. I figured it was around 950, but got home and was 1002fps.

Just shot one group but 3 through the same hole basically at 50m. Furthest right hole is from another day.

This is shooting off a tripod, sitting.

I expect, as long as you stay sub sonic, you shouldn't have an issue with turbulence. So maybe it becomes a matter of the pellet's ability to remain stable at its rotational rate, which gets down to the barrel twist rate. Since the traditional diablo style pellet was designed for much less speed, I don't know what the flight characteristics would be at these advanced velocities. Seems the world of air rifles is approaching a point at which the power levels may require slugs and different barrels. That advances the sport, but I kind of prefer the traditional power levels and pellets. I have cartridge rifles for more power, but, each to his/her own goals.

What about the transonic zone, still subsonic but causes turbulence and instability doesn't it? Yeah i agree pellets aren't designed for transonic and beyond speeds. I shoot many different slugs and enjoy that also, having the heavies flying at 1000 accurately was a happy surprise thats the only point of this thread. 

Are they as accurate at that speed than 900+/-? Probably not, im shooting for fun not as a profession. Just a funny observation wanted to share. I just have a shotgun for bear defense as a last resort as im in bear country and always hunt alone, powder burners don't really interest me.

You're kind of predicting something that's happened already. Slugs and different barrels? They're doing that.

I would like to see if my guess would be in the ball park. The three voids in the Hades tip look to me like they would act as NACA ducts, that would help to reduce the turbulence caused by the diabolo shaped head. By giving a path for the highest pressure air to bypass the sharp (relatively) trailing edge of the pellet head, it appears that the shock wave would be significantly different for the Hades vs. standard pellets.

My R/C aviation hobby background is showing, now. Shoot'em good.

@JimNM this is what I was thinking too. I'd like to see what the group looks like at 150+ yards and if there is any evidence of spiraling as they slow down.

@Glem.Chally good group there. Is it possible to get a long range grouping test so we can see if the slowing pellet is effected much at distance?

Yeah I'll do some testing at further distances once the longer range dries up, at my friends property where I shoot I have a good long distance to shoot from if I want just gotta set something up. Might take a while I'm on the one day a Week off program for the next Month or so. 50m I have all setup already but will stretch them out and see how they fare.
