I received 25 of the 25 cal hades this evening to test. Went right out to test before it got dark and shot all 25 at 50 yards in a slight breeze (zero was for the jsb kings). I was using an FX Streamline with a smooth twist barrel and an Airmax 6x24x56. The pellet is what looks like a cut up mark 2 heavy, much like the 22 version is a cut up 18grain jsb. Weighs in at 26.54grains. Over the fx crono it was shooting at around 830ftps as opposed to 875ftps with the Kings. In fairness to the pellets a few were a bit damaged in transit, however the attached 5 shot groups aren't too bad and I am sure could be tightened up. The pellets also seemed to rip into the cardboard more than the Kings making the holes seem more ragged. Being a tight scotsman I only had a one pence piece for sizing.
I think jsb are on to a winner with the 25 cal Hades.
