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.

    To close this box once you've read it (and the Rules), click on the X in the top right-hand corner.

    Thank you.

  2. A reminder of one of the Forum Rules:


    Do not make inappropriate or offensive posts - including threats, harassment, swearing, prejudice, defamation, deliberate insults or name-calling, other negative remarks about this forum, its moderators and administrators or your fellow members. Even if this is just your own personal opinion, RESPECT YOUR FELLOW MEMBERS.'

    There have been changes made to our censoring software in an attempt to help with this growing problem.

  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.

Todays Tinkering - Internal Component R & D Testing - "the Results"

    Following a previous post of a similar title, I have now concluded my tests both in the Shed and in the field...

    Stringent parameters and protocols were adhered to whist undertaking these tests...

    On test today were 8 of the Wondrous moderators that have been born from the tinkerings of my Shed and the "mad cap" ideas that have emitted forthwith..

    CAVEAT... these tests are in NO WAY designed to under-mine your faith in other moderation systems... These results are PURELY MY OWN and are NOT intended in any way to cast aspersions or ambiguity on other products that fulfil a similar function.

    The Sound Meter used was a BEHA Unitest No. 93411E, which was located 1 meter in front of the moderator muzzle and 300mm to the right and 100mm below. This was maintained for all the mods used..

    The ambient noise level within the Shed (with a small gas heater in operation) was 33.7Db

    The Rifle in todays test was my BSA Ultra SE in .22 cal. and ALL shots taken were DRY FIRED..

    3 shots per moderator were taken with an average reading of the 3 shots being the final result.

    ADDITIONAL CAVEAT - There was an element of "mechanical noise" of the hammer strike. This factor MUST be taken into consideration at the point of the breech.
    However, at 25 yards (arbitrary distance), this hammer noise may have an influence on the actual sound heard..
    Also in the Shed, there are no "soft furnishings" or "egg box baffles" on the walls to dampen down any resonant frequencies. Outside in the open air the sound vibrations are not resonated as much.

    SO... without further ado.... here are the results.

    The moderators on test (in descending order in the photo)

    1) Newly designed mod with "revised internal components" 47.2Db

    2) Shorty mod (standard internals) 60.1Db

    3) Db Mod - recently featured and with some specific internal features 53Db

    4) Shroud and Moderator (standard fitment on my Ultra for hunting) 51.5Db

    5) Hybrid mod 64Db

    6) Halloween mod 51.6Db

    7) Pressure decrease mod 61Db

    8) The "Cannon" pressure increase mod 47.9Db

    So Gentlemen.....

    There you have it.... the results of the testing in my Shed where every unit was tested EXACTLY the same.

    It goes to show that SOME of the internals that I have made/developed/come up with.. are actually EFFECTIVE.

    However, I do not think for a moment that branded proprietary manufacturers should be worried.... as I shall only use my OWN DESIGNS on my own units....

    The "field testing" results can be found in the HUNTING section of this most prestigious Forum...

    I thank you...
