    Given the relatively small swept volume I doubt you could extract more that 14ft/lb from the little 99.

    I could be wrong.

    I'm sure more able tuners will confirm this, but the reason the '99 is considered such a sweet shooting air rifle in .22" is because with its' internal dimensions (swept volume and piston weight, etc) its' optimum is sub 12fpe. I don't think there's enough spring room for FAC. You'd really want to look at an HW80 for FAC springers, although in the USA, they run the '95's at about 15fpe.

    Hard air magazine review on a hw50 's
    muzzle velocity for the Weihrauch HW50S air rifle tested by HAM peaked at 799 fps. This is a .22 caliber model, don’t forget: the .177 version would shoot significantly faster.

    This muzzle velocity – obtained with Gamo Raptor Platinum 9.7 Grain alloy pellets – was combined with a peak muzzle energy of 13.74 Ft/Lbs.

    Hello to All,

    Below is what HAM got for the HW50S.

    For what we would call 'normal' pellets, the output is ca. 11 - 12 ft.lb.

    Have fun

    Best regards

    Russ

    The HW80 at FAC level done properly is a sweet springer to use.

    You might manage to get a bit more than 12 but you would need a much heavier piston and bigger spring. It would suffer from piston crash. It would be horrible to shoot.

    pointless - 12-13 or so max

    as already stated go with a 95 for ~ 16 FP, or an HW 80 for ~20FP, job done
    Always looking for any cheap, interesting, knackered "project" guns. Thanks, JB.
