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.

Even if this is just your own personal opinion, RESPECT YOUR FELLOW MEMBERS.'

  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 just bought a .177 99s just for plinking in the garden.I have put a setback trigger in it and its a great gun,but the other day I had the chance to shoot a .22 99 and it was even nicer to shoot then mine,so I was thinking with the 99 being a short stroke could I detune the power to about 600 FPS or would it make the action lazy and slow?

    Micah,

    take a little off the spring, it will make it a bit softer to cock too.

    I have some springs that have already been cut Micah, If you would like me to pop over one of the days and switch it to see what it will do?

    saves cutting your original!

    I know how to do it but some guns with a longer stroke go lazy .I just wondered if anyone has done it i read somewhere the hw50 was originally designed as a 8 FPE gun in .177.

    It is only 10 now I looked at a 30 but it was a bit too small for me.I have read the 99 in .22 is the perfect setup for our power levels,but I must admit I was well impressed when I shot a .22 version.

    Yes agree with above hw 30 looks and feels identical just got one for my wife ,its nearer 9 ft lbs its in 22 and shoots like a dream ,in fact I own many guns but have to say this little gem is now one of my favourites and I want one too. My wife loves it ,and I took 2 rabbits with this at 30 yards and they dropped straight away using superpoints which it loves .I like it that much am off to Yarmouth Saturday to to see chris at youngmans to see if he can order me one in 177 !.bought my wifes secondhand ,but they very rarely come up for sale which says something they are a very underated rifle and they come fitted with the full metal sights with changeable elements and the record trigger .

    I bought my first 99s in .177 last year just to add to the collection but loved it so much i had to have it in .22.Now have 4 two with screw cut barrels including the Black which is a German import stainless look with black stock & mod.
    My advice is get the .22 as well as it is perfect at sub 12.

    Buying a Hw99s or 50s in Germany would be very docile at sub 6ft lbs.

    I think the stainless black stocked Hw50s comes with a mod fitted, so I'm guessing the barrel is threaded ?

    Visit a gun shop John, would love to hear what available out in Germany, compared to the UK.

    Just an update I have lopped 3 coils off the spring and its doing 640 FPS with Superdomes so about 7.5 FPE.Its shooting even nicer and the action is still fast so I think it will be ok.I like this gun even more then the two 95's I have owned and I think for 200 ish quid you cant beat them.
