    So what you're saying is, make a lighter piston and put a better piston seal on it (as well as putting the spring back in) and it will be much nicer to shoot and probably make power?

    BUT IT'S GERMAN! and you know that's a big no no in my books

    There is that other thing that there might be a new British break barrel finally showing it's beautiful head soon

    The barrel on your ProSport is German, and the stock is probably Italian. So you are going to have to sell it back to me, yes?

    I think it's time you invested in a decent pre-War BSA. Get one that is not collector's grade, put in a nylon parachute, proper guides and spring and put a scope ramp on it. Then get a TX200 CD trigger unit and have that grafted on to it - T20 has one of these and it is pretty good. You can make up a full-length laminate stock made up for it. It will be as British as pork pies and I think you will like it. The build quality on some of those old BSA is truly remarkable.

    Nope it's staying with me, it's the last rifle I'd sell if I had to sell my collection.

    The pre war stuff don't really do it for me, the youngest rifle I'd consider is a mk1 Airsporter, I can't even put a bloody spring in a Theoben and get it to shoot properly let alone try and graft a different trigger onto another rifle.

    What is this new British break barrel you are hinting at? Is it made in China?

    If that's sexy then I'd hate to think what your ideal woman looks like

    The the new rifle that has been '' at by a certain teaser on here, certainly won't be Chinese connected hopefully (unless one of the machinists had a pot noodle for lunch), it probably won't happen and we're just being lead up the wrong path and a mk4 version of something else will be forced upon us instead.

    Better piston seal will always help, Pete.

    Lighter piston in a wider bore gun will certainly give quicker piston acceleration, Pete, but might not make it nicer / any more accurate as, depending on other set-up parameters, you're more than likely to get greater piston bounce, which is much more detrimental to better accuracy / improved hold sensitivity.

    I've sometimes wondered in this scenario, however, if we went for an aluminium piston to reduce overall weight, but a nice, heavy steel top hat (idea here thinking of increasing the cross sectional density) if this may help?

    Any thoughts, JB?


    Of course, going back to the original flavour of the thread, at our power level, narrow bore is always going to be best.
