I don't know if you have an interest in a heavier pellet, but my .22 K carbine shot the JSB 18 at the velocity you are getting with the 14. And that was close to max HST, about 96% probably. I didn't change the reg set point. And if your BP has the longer barrel, then you have more higher speed/heavier pellet potential. My carbine was the 410mm barrel, about 16 inches.
