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.

    'Behaviour

    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.

    I have recently aquire a bsa r10 mk2 .177.
    Unfortunately its only putting out between 7-8ftlb with a variety of pellets.
    Since its second hand it has no warranty, and the seller swears the gun was full power when posted to me (I 100% believe the seller as they are very genuine), so what caused the power drop is unknown to me.
    So as per title, I am wanting to up the power to around 11.6, can anyone tell me the easiest way to up the power on the R10.

    AS PER FORUM RULES, PLEASE COMMENT ON HERE WITH ANY IDEAS WHY THE POWER DROPPED, BUT ANY INFO ON HOW TO ADJUST THE POWER VIA PM ONLY.
    Thanks in advance :)

    is the power consistently low or is it 'up and down' and have you checked it when the pressure gets below 100bar because some regs on the r10 produce a bit more power as the pressure drops and pm in bound

    It sounds like the reg needs a service and resetting.

    It's one way of giving the Reg a reset, the old turn it off and on again trick

    Are the regs vented to atmosphere in these guns? If not it sounds like a classic case of the reg becoming pressurised due to a leaking seal..

    It is a "reset" for the reg, they sometimes get stuck or the Bellevilles can move and the reg pressure changes.

    The new HuMa R-10 regulators should be in stock very soon if all else fails.

    That seems to have sorted out the problem :up:
    I am going to give the gun a good running in to see if its a definite keeper, if it is I was thinking of sending it to you for a tune, which would you consider best, the HuMa or the tench regs?

    I’m pretty sure it’s calibre and barrel length specific, so what ever your r10 is

    Cheers

    XTX are no longer dealing with rifles, this is a six year old thread.

    Order direct from Humax and tell them the rifle and barrel length you have.
