I agree that 775fps is the maximum for the HFT500. Mine shoots very consistently between 765 to 775, but starts to spray pellets like a shotgun at anything over that.
Just relooked at this and the spikes where how the laquer had dried, and i agree there a to tight fit i even sanded the laquer down and its still a a very tight fit those to bits of sponge at the fore end must make things even worse.
I think theres way to much laquer on the inletting of mine.
