    HW100 Power Issue

    Could any HW100 gurus give me some help on this please.

    Filled gun to 200bar
    Using Bisley Mags .177
    After 80 shots down to 150bar ish

    Shot No1 - 446fps
    Shot No20 - 467
    Shot No40 - 515
    Shot No60 - 564
    Shot No80 - 679

    I've never had it apart, never messed with reg or hammer spring, only changed the cylinder to A&M

    Could this be a problem with the hammer spring?

    cheers

    Firstly you're better off with the standard cylinder rather than an A & M.

    The fault is likely to involve the regulator, it could be dirt in the Belleville washers or the piston O ring faulty casing it to stick. It's unlikely to be the hammer spring or you'd be getting irregular readings across a charge.

    Hope this helps.

    Give Shaun a bell, Matt - he’ll sort that no problem.
    Put on heading 270, assume attack formation

    Cheers guys

    Craig, I did wonder if Shaun had a play with them.

    Why better off with a standard cylinder as opposed to the A&M ?
