You saw the numbers I PM'd ya, what are you shooting pellet wise, what are your hammer throw and spring adjustment to get those numbers. It was suggest that my spring was weak, its possible even with a fairly new gun, so it was replaced with a slightly heavier spring amd just a little longer.
with this heavier spring my numbers were still not any where near your numbers, using both 14.3g & 15.9g pellets.
