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.

    I asked this on a Facebook page.
    Why do people get hung up on numbers on there chrono, so we do a test, let's say we shoot 3mags and we get a deviation of 5-6fps and we call it done. we have our tune and now where happy.
    But in reality it's not the case, what we should do is stick the gun on the bench take a shot, leave the gun twenty minutes take another shot then 15 then another 10 shots at scattered times because in reality that's what you would be doing in the hunting scenario.
    I wonder if we would be happy then.

    I would be interested to know if anyone has done a chrono test this way.

    Thats what i do :) its a good way of checking for reg creep and consistency .many people rattle off shot strings . i look at the times between shots on some and they are a matter of seconds . which is not real world . to get a true reading you need to take your time .
    :thumb: nice one mate

    ps . a must for PCP owners...

    It would take some time a patience to complete a mag. Especially if you waited 30 mins and took the shot and chrono didn't read it. Might give it a go next time I'm messing in the shed.

    I use a crony just to give me a power output , yes I look for consistency but I don't and wouldn't get hung up on it , simply because sometimes the most consistent are the least accurate so it's more about groupings at a decent range rather than a small spread on a crony test

    I have previously done this, but more to check power through the fill. Fire off a string across the chrono have a chat (when at the range) plink for a bit, run another shot string, repeat till done.

    If you hunt, fine, but most of the people I know dont. We tend to run a check after filling, then periodically to get 4 or 5 strings till it goes.

    Youre assuming everyone "in the real world" shoots as you do. Pretty arrogant really.

    Shot strings are exactly how those in "the real world" of bench rest shooting fire where you have 20 minutes for 20 shots. Consistency and accuracy are vital when aiming for a 2mm target

    Yes, which was what I was trying to prove. I was having constantly shifting POI on a daystate MK3. A visit to Staffs custom rifles later for a proper service and it shoots properly and constantly, and hasn't missed a beat in the last 3+ years. (Rifle had come to me second hand and very cheap, and had what turned out to be solenoid issues.)

    Three shots through chrono when I return home, allows for a picture over time as to what's happening internally. It also confirms I am not creeping into naughty territory.
    I take 3 shots because I wouldn't trust just 1.

    Enlighten me please, what, pray tell does a solenoid do for an air rifle?
    The only remotely " electric" thing involved with my Springer, is plugging the ear buds into my phone..( I like music when I Varmint shoot.)
    Serious question, what's the function?

    the real world of bench rest :facepalm:
    Consistency and accuracy is about rifle set up .
    how do you think you set a rifle up for that .
    how do you think you find out if your reg is creeping in the minute between shots .

    arrogant is the person who speaks for the one .
    we speak for the many . for the lads with who are learning how to set up springers . pcps for targets ..hunters .. the lads setting up regulators so people like you can hit your 2mm targets . this forum is about people who come together to share info of how to .... not I am

    and just for your info when i got home i took 3 different spring rifles out . which i haven't shot of at least 12 weeks and standing yes standing not bolted to a bench...... in wind i still managed a 3/4 group :mao: arrogant ...my back side
    if i was arrogant i would not be on here coz i wouldent need anyone else coz i would know it all ..........

    Ps ... 2mm target 4.5 mm pellet yep plenty of room for error then . 4..6 mm ring with a 4.5 mm hole in the middle of it would be better . and there are quite a few good lads on here that do that . look up polo mint challenge .

    pps .... sorry not shot with a springer ... i wish tho . :)
