    Default Weihrauch HW35 "The Classic" | Review

    Weihrauch HW35

    When purchasing my first air rifle in 1980 the final selection was between the Weihrauch HW35 with its breech lock and leather piston seal
    and the BSA Mercury with its smooth shooting floating head piston with O ring seal. Back then the BSA Mercury was my choice.

    So now its the Weihrauch HW35 chance to impress me.

    The HW35 has been in production since 1951. The latest version retains the breech lock but even with lots of improvements to the mechanicals
    and stock design it still retains its classic look.

    The new HW35 that I have was manufactured in 2011, so it has been in stock at the agents for a number of years.
    The barrel and massive compression cylinder are treated with a nice deep bluing. The stock has a very attractive striped grain
    and is in the current Weihrauch walnut stained beech wood.

    The HW35 handles and shoulders well with its more slender plainer stock. I was surprised to find that it weighs 4.2 kg
    with the Gamo 4x32 AO compact scope ( weight 370 gm). With the small cocking lever slot there is lots of room for a comfortable
    grip on the forend. I also like the single front stock screw (as also on the HW30/50). The stock forend has the retro finger grooves
    to maintain its classic look.

    When I tried to clean the barrel i found that my DIY bore snake would not fit down the muzzle end, So I made up a new design
    and also modified the 2mm nylon line version ( the cord/string does last ) (See DIY Section)

    Note the rounded forestock end and smaller barrel latch cut out on current HW35 rifles.
    To release the barrel latch you place your fingers over the barrel and pull the latch forward with your thumb the barrel drops a bit
    and then you slide your hand to the end of the barrel to complete the cocking stroke. The rifle with its articulated cocking linkage
    is reasonably easy to cock with its very smooth action.

    The firing cycle is short with mild recoil and spring twang/vibration. The Record trigger breaks cleanly and consistently at 2 Lbs.
    Which is fine for a sporting rifle.

    One of the many updates, the barrels are fitted to the breech block with a locking nut.

    I had a go at using the supplied open sights at 10m and they are good but I manage better with the HW30S
    as the rear sight is closer to your eye..So to try and do the HW35 justice I have fitted a Gamo 4x32 AO compact scope.

    After fitting the scope and zeroing at 17m I got some good clover leaf groups but when I had a go at a 5 shot group
    the shots were drifting to the left. So I checked the forend stock and trigger guard stock screws and they needed tightening
    also the rear scope top saddle was tightened.
    So the group shown can be improved on as the scope had to be re-zeroed again. The five shot group can be covered by a ten cent piece
    (edge to edge 14mm as measured)

    Checking the power output and velocity using my Shooting Chrony :
    Average Velocity 749 ft/sec (10 shot string) Muzzle energy 10.5 ft/lbs using JSB Exact 8.44 gn pellets
    I will recheck these figures once I have run in the rifle but they are in line with Weihrauch`s claim of 230 m/sec (755 ft/sec)

    Verdict :

    In my opinion the Weihrauch HW35 is still a "Classic" . It is a man sized air rifle with its large diameter compression cylinder
    and solid build quality and retains its character with modern updates.

    To some it may appear old fashioned and why not rather buy the HW50S, it has the same power and accuracy with lighter weight
    but it does not have the "magic" of the HW35 maybe its an older air rifle enthusiasts thing .

    Hello Mercury,

    Congratulations on owning an excellent air rifle.

    I also have an HW35 in 4.5mm caliber , and I agree with your review , this rifle is a classic , it may not appeal to some shooters , but this is their loss .

    Your rifle's power output is almost identical to mine , so don't worry about that.

    Accuracy increases once the rifle has been shot a bit , the loosening of the stock screws will stop after a while.

    I also own an HW 50s , which develops slightly more power , these 2 rifles have a completely different feel and firing cycle to them, accuracy of these two rifles is identical in my experience , it is hard to choose between them , get both if you can.

    I suggest that you ditch the scope and fit a diopter (peep) sight , in my opinion this just increases the pleasure of shooting the HW35 as it was meant to be shot.

    Enjoy your Classic.
