Here is what I'm getting with the RW .22HP at 35 yards. Pellets straight from the tins, no washing nor sorting. Aztec Emerald 5.5-25x50 scope settings are indicated ( e.g. E: 3.5 W: 0)

25.39 JSB Monsters (original version) perform well on LOW (est. 751 fps), MID (est. 858 fps), and HIGH power (931 fps).
21.14 H&N Baracuda Match are just "ok" on LOW power (est. 889 fps), but inconsistent
18.13 JSB are pretty good on LOW power (est. 889 fps)
15.89 JSB are crappy on LOW power (est. 949 fps)
So, it seems that my RW .22HP likes the 25.39 gr Monsters at all three power levels (nice!). These are probably the best performing pellet with my gun. And JSB 18.13 gr are pretty good as well.
For most of my shooting, I prefer LOW power, as the performance is good at my 35 yard range, the shot count is well over 150 rounds, and the sound level is lowest. I bump up the power for longer range and taking pests out of the picture.
Shot count:
LOW Power about 150-170 rounds
MID Power about 125 rounds
HIGH Power about 85 rounds
Overall, I'm pretty happy with the RW .22HP. Trigger and cocking action are, of course, superb. And shot count on LOW power, at well over 150 rounds, on a fill is enjoyable. Electronic selection of power levels is really nice.
"Regulation" of air seems quite consistent. I have not yet chronographed the rifle... that is to come before too long.
