Yep, my stock HW 95 gets about 680 fps for pellets in the 14.5 grain category. Around 15.4 foot pounds.
If you want velocity, go with the H&N FTT Green 9.56 grain. Stock the HW95 shoots those at 850 fps / 15.5 foot pounds. It makes sense because the pellet is in the .177 weight range. At closer ranges it'll shoot flatter than the heavier lead pellets. At 10 yards the lead pellets, although still slower, start edging it out for retained kinetic energy. So if you want more punch at longer range, the lead pellets may be better.
The hybrid plastic/alloy H&N Prometheus 9.0 grain gives you a skosh more muzzle velocity/energy: 883 fps / 15.6 foot pounds. But it has accuracy problems and more downrange energy loss than the FTT Green.
According to my amateur testing, the JSBs have slightly lower initial velocity and energy, but seem to retain it better down range. For example, the JSB 14.35 grain Express loses only 4% of its kinetic energy at 10 yards, compared to 10% for the H&N FTT lead pellet. The JSB 15.89 grain Jumbo loses even less, around 2%. It's a total mystery. Maybe JSB coats them with teflon or there's an aerodynamic boat-tail effect. JSB pellet skirts seem to be more feathered at the edge than the H&Ns. I'm just grasping at straws here.
