    How powerful is your HW45?

    Just bought a combro chrono and was pleasantly suprised to find my 15 year old .177 HW45 running at 5.5 FPE (eley wasps), thats with original spring and seals!

    Mine's a week old (still dieseling), and on Weihrauch F&T's I get;

    ft/lb
    4.98
    4.94
    5.14
    4.94
    4.88
    4.88
    4.95
    4.98
    5.01
    5.06
    4.98 Average (SKAN chrono)

    Let's call it 5ft/lb!

    I'll try it with something heavier, see if that makes any difference.

    Update: Just tried it with Bisley Magnums, and the power went down to 3.2 ft/lb !!!!!

    Heavy pellets in a pistol are a waste of time, they are pushed out at a much lower velocity compared to medium or light pellets that the ME suffers.

    Which are the lightest pellets, and the people that get almost 6 ft/lb, what pellets do you use?

    Eley Wasps are one of the lightest pellets at about 7.3 grains, as a comparison mine drops to 5.2 FPE with FTTs.

    I prefer Beeman FTS (H&N FTT) in my pistol for the accuracy. Beeman sell their Laser pellets which are 6.5grains. I also believe RWS Hobby are a light pellet too, give 'em a try.

    Done a bit of testing with my very early HW45....

    Milbro Match 7.7gr........av. 5.08 ft/lb
    RWS Super H point 7.28gr......av. 4.94 ft/lb
    RWS Hobby 7.1gr........av. 4.92 ft/lb
    Eley Wasp 7.35gr......av. 4.73 ft/lb
    Bisley Magnum 10.46gr.....av. 4.08 ft/lb
    RWS Supermag 9.3gr......av. 3.89 ft/lb
    H&N Rabbit Magnum 16.8gr.....av. 1.73 ft/lb

    The RWS Supermag's are a surprise - I expected them to do well
    The Milbro Match were amazingly consistant with only 4 fps variation over 5 shots!
    This particular gun shoots tights groups and most smoothly with RWS Hobby although I will try the Milbro pellets at some point now.....

    When new, my .22 HW45 was getting 6.0FPE or very close to it. At that time I had lots of Beeman FTS pellets which the H&N manufacturer calls Field & Target Trophy. I had a heavy lot that weighed 14.9gr and hit 425fps.

    http://my.tbaytel.net/~coopers@tbayt...LOCITY_TESTS_1

    My .22 HW45 is now on it's second spring. I changed the original at approx 7500-8000 pellets but I could have got more out of it. The spring change was part of my review. Anyway, the new spring has seen around 6000 shots and is now doing 415fps with 14.2gr RWS SHP (5.4FPE).

    Cheers,
    Todd

    Did a little more testing on my .177 yesterday, just curious.

    RWS C02 3.2fpe

    RWS Superdome 4.0fpe

    Defiant 4.1fpe

    AA Field 4.3fpe
    Stopped there a ricochet T*####*ED my trigger finger (From a catalouge backstop)
    Result not much change from last time I checked it although i cant explain the initial drop from over 5.0fpe.
    John

    Hi webranger,

    Here are a few possible problems to check for when velocity drops in the HW45.

    1 - Breech seal. Nicks or missing chunks will effect velocity. Sometimes a thin shim under the seal will help a sloppy or worn example.

    2 - Broken mainspring. The HW45 often sees close to 10,000 shots before the spring is broken. I'm not sure if you shot this much in 2 years. Velocity will sometimes drop a bit when you pass the halfway mark but you had a large drop. Possibly the spring was not a good example.

    3 - Dry pistol. I find I get best velocity when there is a very slight dieseling. After the shot I can see a very faint, palm sized, whitish cloud at the muzzle. There is no loud bang from the fuel burn and velocity is consistent.

    Cheers,
    Todd

    I had one as a kid. Loved it! It still delivered reasonable accuracy and power even with a broken spring.

    Fully tuned and serviced .177 action with .22 barrel over 5ftlbs. consistantly.

    I got a bit worried when I fired the first shots as it was over 6ftlbs but it has now settled down nicely, it must have been grease in the compression chamber.
    Enjoy every step you take, you never know which one will be your last.
