I just received my FWB124D back from Precision Pellet, It was shooting 700fps with 8.4gr JSBs, now it is shooting in the 780s. Rick said the seal and spring that were in the rifle were fine and looked barely used. I do not know why it was shooting at 9fpe, maybe the seal was not fitted to the receiver??? The seal that came out looks like a Maccari seal.
