1. The Forum Rules have undergone some minor changes and updates.  Please take the time to read them; it will only take a couple of minutes of your time. By doing so, you lessen the chance of incurring the wrath of the moderation team or making yourself look foolish to other members.

    90% of users posting adverts in the Sales forums need to be reminded to read the rules as their posts are wrong.  This is unnecessarily time-consuming and will no longer happen - if your advert doesn't follow the Sales Rules it will be deleted and you'll have to start all over again.

  3. Dear members,

    Our membership (like our country) consists of people from all walks of life; different in far more ways than can be listed here and each with a different view based on their experience of life - regardless of their colour, religion or cultural heritage. Every single person in the UK has been born of mixed race – we are a multi-coloured and multi-cultural country.

    As many of you are aware there are a handful of individuals amongst this membership that persist in making provocative, inflammatory, racist and otherwise offensive comments. This has been happening across the forum to a certain degree but is most especially prevalent in the Adult section.

    The moderation team has tried to stay on top of this, however unfortunately because of the ‘offensive’ nature of much of its content we don’t monitor the Adult section quite as much as perhaps we should. As a result much of this behaviour has gone unnoticed unless it has been reported to us. While the team always intended to take a "light touch" approach to the Adult section it would seem that some people aren’t quite adult enough to be left unmonitored after all.

    This behaviour is, and always has been against Forum Rules as well as the specific stipulations of the Adults forum and it will no longer be tolerated. We feel it's time to draw a line in the sand and as such from this point onward offenders will receive an immediate and permanent ban from the forum.

    In order for us to achieve our goal of restoring the forum to the friendly and tolerant place it once was, we ask that ALL members be mindful of the content they post and help us to stop unacceptable behaviour by using the 'Report' tool at the bottom of any offending post - the results of which can be seen only by Admin/Moderators.

    You should all receive a copy of this message by PM.

  5. Postings on Politics, Religion & Controversial Off-Topic Material

    The majority of users do not want to read about these subjects and people have left the forum as a result of it – this is after all an 'Airgun' Forum. It’s all very well to say they don’t have to read it if they don't want to, but as most of us use the ‘New Posts’ button there is no easy way to avoid it.

    All AGF staff members are in favour of people being able to discuss what they want, but we have to draw the line somewhere if it is upsetting other users. We don’t want to read about these topics either.

    IMPORTANT- The discussion of politics and religion is no longer allowed anywhere on the forum (including the Adult section).  The only exception is if it's airgun related - they must be put in the Airgun Related Politics section..

    We will not tolerate bullying or personal attacks, racism or any other offensive 'isms'. we will remove these topics from the forum, we will not give you an area where you can abuse each other. We will not hesitate to ban offenders.

    As Al says unless a choke is perfect it effects accuracy and infact my best barrels are chokeless after visting Al

    It all depends on the individual barrel.A choke is only there on a barrel to take into account for any perceived slop in the said barrel so a choke is not always needed,most guns shoot fine without a choke. None of my barrels on my guns have a choke . ;) I do however have a .20 LW match grade barrel here off my Rapid EPR that came fitted as std without a choke and that could do with a choke, a very slack barrel tbh and groups to match .

    I cut a bsa .25 choked barrel in two and of the two the unchoked barrel far out performs the choked one

    The choke on my Harsan AT44 was far too tight
    and accuracy suffered badly.
    I machined the whole choked section off ,recrowned it and fitted a 15mm silencer adaptor
    to replace the section I removed.
    Now it shoots very well indeed, in fact as well as my old AAS410 .22 with a good selection of ammo.
    Chokes are not always necessary it seems.
    Happy days.

    The choked barrel helps more pellets to go well, with the unchoked barrel it is probable only a pellet is fine.
    On my rapid .25 over the original lw I also have a choked bsa that fired well the 1.64-gram jsb and good jsb heavy from 2.20 grams.
    Eliminated the choked, those from 1.64 have discreet accuracy but those from 2.20 give to 50 mt 8/10 mm for 5 shoots.
    Which one to use? very difficult to say which is better if you do not do tests with different barrels and different pellets.

    u find a real working choke is just a thou more on feeling a easy traveling pellet when u test it with a rod test, and I mean a thou.
    not hammer a pellet out sets I worked on.
    soft pellets skirts expand a lot in the rifling with a blast of air , so don't thinking there rattling down a non choked barrel. Al
