    Default HW97 FIRST IMPRESSIONS

    I decided to add a HW 97 K in .20 to my pair of underlevers, a .177 LGU that I shoot HFT with and really enjoy and a TX200 in 5.5mm that I have had a love hate relationship with since 2014, but that is another story.

    I initially wanted a sporter stock, being a traditionalist but Rosenthals only had the KT in stock, so that was it.

    Dragged it home, a few pulls through the barrel, not half as bad as the SPA 5.5mm I had a bad experience with a few months ago and into the garage for a few shots.

    The first shot went right through 16mm plywood. Diesel de luxe, major time, 3 more shots with similar results, this thing needed a serious clean out.

    F#$K the warranty, out come the tools and I had the bitch in bits in minutes.



    Piston seal completely covered in grease!


    Piston face and groove grease covered



    Compression tube carbon fouling



    Transfer port face carbon fouling



    Quality of bluing of cocking lever latch housing



    Quality of barrel and shroud bluing



    Corrosion visible at barrel and receiver interface



    Blued burr visible above cocking lever pivot pin hole



    Corrosion visible in breech



    Corrosion visible in trigger housing



    Dissimilar finishes of butt pad metalwork



    Poor fit of butt pad metalwork



    1st 20 shots 25m rested



    1st 20 shot chrony string

    LIKES
    • Stock finish and fit to action
    • Accuracy
    • Ease of loading
    • No ratchet sound when cocking
    • No manual anti bear trap release


    DISLIKES
    • Quality of bluing
    • Trigger - might have been a Rekord 20 years ago, but not a patch on Air Arms or Walther for ease of adjustment
    • Safety cannot be re-set without re-cocking, same as TX 200
    • Push button cocking lever release, plain ball detent like TX and Wally would suffice
    • Butt pad abortion is just plain horrible!!!

    All springers need a little work before they shoot properly.
    The 97k still remains my favourite airgun of all times and I own several.

    Regarding the butt pad, it does not look like the original factory butt but an aftermarket butt, badly fitted? Rust anywhere, send it back for an exchange. clearly something is wrong as HW's are normally amost perfect

    I agree, that does look out of sorts for a new weihrauch, dare I say it could be a returned rifle and sold again as new? Id return it.

    From what I have seen a lot of the KT beech thumbholes have the aluminium adjustable butt plates fitted. The HW98 also has that type of pad. The alloy used in these is not brilliant and you do get some colour variation when they are sized to fit, the plates come oversized and require filing down to size.

    In terms of the grease and dieseling - fairly typical of a Weihrauch. Whilst they are still a pretty well made product, the standard of fit and finish during assembly doesn't seem as good as they were some years ago.

    Oh,
    HW97 need to be dissasembled and cleaned before first use. They use alot of lube which burn piston seal. As I see in pic your piston seal is K.O thats why your shots energy jump so much on chrony. Buy new piston seal , clean up piston room to be totaly dry. There cant be any lub front of piston just only side of seal and end of piston need to be lubed. Dont use any silicon lube cause its burn eazy. I use Napier-3034A-Power-Airgun-Grease and I achive after awesome result (on 10m Hole to hole with Gamo CFR whisprt IGT and shooting JSB exact .177). Before I use one adtitive to transmision oil and results was a little better then Napier grase.

    Pistons sels mostly if they are to old loosing pressure and make your piston hit hard and as you can see on your one make damage.

    There you have video how properly LUB HW 97 piston :

    Weihrauch HW97k Cleaning Lubrication - YouTube

    What you need to do:
    Replace :
    Piston Seal
    Transfer port Seal
    Properly lub piston and make shure you dont have any lub front of piston
    Clean Barrel becaus there will be alot of carbon and that can harm ur barrel.

    Enjoy more precisse shooting.

    After living with the HW97 since December with a less than satisfactory trigger I pulled the following mods:


    Cut the tab that adjusts the trigger first stage setting off - who wants to adjust a trigger by bending a tab?



    Moved the trigger pivot point forward as far as it can go - better leverage on the primary sear.



    Added a grub screw to adjust first stage travel to the trigger guard



    Easy enough to adjust first stage now



    Grub screw touches the trigger at the sweet spot

    Still had to go through the trigger guard on off on off to set the second stage but am happy with the results.

    A new trigger with a better fit to the pivot pin to reduce sideways slop with 2 grub screws like "normal" gun makers employ for trigger adjustment is on the cards.
