    Thank you for this information. I note, however, that you would be running a tad hot if your figures are correct. Have you recorded the requirements for 'not hot' version?

    Cheers, Phil

    Hi J
    Thanks for the correction. I have added the info to my small database.
    From your dimensions, your SFS spring seems a bit heavier, but shorter, than some others.:

    WEIHRAUCH HW95 19.6 13.6 3 245 31 Cobham
    WEIHRAUCH HW95 19.8 13.6 3.1 270 Versandhaus

    I hope the above is self explanatory. the Cobham and Versandhaus terms are where I found my information.


    And to the post regarding Titans 13, 14, 15 .... my info only goes up to No. 12 so I would like to know as well if they do more.

    Cheers, Phil

    This is the spec of the spring in my new .22 cal HW50s from DB Shietsport Holland.

    wire diameter 3,15

    active coils, 28

    inside diameter 14,25mm

    free length 248mm

    gap between coils, 6mm.

    Both ends are finished rather than cropped and it pushed hobbies out at 695 fps from the box. Now it bits for a spring crop and the fitting
    of a guide and top hat!

    just ordered a hw97k .22 from Netherlands he never had the uk spec rifle in stock so I ordered the standard its on its way with the spring removed so I have the problem of cutting this 14.7ftb spring down to make it 11.6ftb, the specs on the spring is as follows, Energy (Joule / ft.lb) 20 / 14.7.
    Link to gun
    http://www.krale-schietsport.nl/en/w...ch-hw97-k.html

    I have a chrono but I want to be able to cut it so i don't over cut and end up having to pack the piston out with delrin washers.
    watching videos of 97 uk 12ftb strip downs it seems that when spring block is removed the spring guide and spring seem to be flush with the threaded chamber should i use this as a guide?
    I have no idea what type of spring is in this gun as I don't get it until this Tuesday and would appreciate any help I will upload spring dimensions when I get the gun on Tuesday.

    Cobham are not a spring supplier. The reference is to the book 'Air rifle and air piston maintenance and repair' by Q Cobham.
