710 ft/s with 14.3 gr pellets = just over 16 ft/lbs
Must say, the HW57 is also one of my favourites.
Only used it once before and was blown away by the accuracy. It was almost to easy to shoot ragged one hole groupings.
I wouldn't mind having a HW57 or a HW80, but my wife will really bliksem me if I spend any more money on toys. I still have the BSA lying at home and I don't even get a chance to shoot with it, not to mention all the other "project" guns.
