As far as I can remember I registered around 3 ft lb. The fps was between 400 to 450 with various pellets, 7 grn to 8.3 grn. I did have one which the power was up slightly as I fitted a special spring that I ground down the O.D. to fit the piston. This made it a bit hard to cock and put a lot of strain on the sidelever. The chap I sold it to on here took the spring out. Was the prettiest 65 I have seen with a kind of "tigers eye" patterned wood grips.
