Air Arms S510 .25cal - Hades

I have a .25cal AA S510 on the way and was going through my ammo and I have several tins of .25cal Hades sitting here. Has anyone ever used them in the .25cal with any success? Although this is not what you would consider to be a slug gun, I have seen a couple of videos (one .22cal and one .25cal) where the rifles seemed to be shooting slugs okay, just not super fast. Any experience with the .249, .250 and .251 diameters (and different weights) would be appreciated.
 
I've heard that the 510's are a bit underpowered when it comes to slugs. I've been using nothing but .25 Hades in my Royale since December of 2019 when I 1st tried them. They're even more accurate in that gun than the JSB's it was designed around. Hope they work as well for you but I know they just don't work well in some airguns. Mine is shooting around 875fps.
