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.

    Just reading a book at the moment called "Country Fair".It was written about 50 years ago. It says that in June when the grass gets high its increasingly harder to shoot rabbits with a .22 rifle .Then says that "to avoid fiddling with sights, the Ommundsen "Negative Angle Battle Sight" principle is useful. You sight the rifle accurately for 60 yards and then, whatever the range of the target from 20 to a 100 yards, you aim 2.5 inches below the "bull"". Any one ever heard of this, I certainly haven't!:confused:

    ive heard of something simular.

    on my SR scope. you zero at 30 yds and then anything between 15-25yds uses the same aim point

    I don't think they mean air rifle when they say .22 rifle. :)

    I've heard of similar ideas the rifle in the book will be a .22lr rimfire and 60 yards is quite a close range for zeroing a rimfire there has been a similar idea for airguns the idea bein if you use .22 the normal zero is 25 yards in .177 35 yards by reducing that zero to 23 yards in .22 and 29 yards in.177 you should be able to aim dead on bull from 10 yards out to 25 yards in .22 and 15 yars to 35 yards in .177 and it will be close enough to give you a clean kill.

    Those few extra yards just flaten out the sight picture enough to reduce the holdover/under to such a small amount that by aiming dead centre each time your close enough.

    I've messed around with it and it does work but when you want to shoot beyond the 25 yard or 35 yard points it becomes to big an adjustment to work out on most scopes

    Yes it will work to a degree for most guns, but it all comes down to the vital kill zone size.
    The Negative Angle Battle Sight is based on a human so you have a bigger vital area to shoot at.

    i think the military snipers class the whole torso down to the gut as a kill zone

    Correct, you get a nice bit of 7.62mm (or larger in some cases) in there it'll definately tingle a little. If it doesn't kill you it'll definately put you 'out of action' for a little while.

    well i think thats the point isnt it?

    not to kill but to wound:confused:

    say now they try to retreat and they get a man down if hes dead theres nothing you can do so you leave him there, diferent story if hes still alive!

    if they try to take hin they lose yet more people out of the fire fight so you can come in and over run them.

    plus if they did leave a liveone behind you could get some intel of him.

    That's the idea behind 5.56mm. It's been proven many times since the calibre was introduced into modern infantry tactics.

    7.62mm is designed to kill, if you need proof, how about it's capable of going through pretty much every type of body armour there is?

    As for extracting 'intel' they stopped bothering with that after the first gulf war. It's only the hierarchy that still believe in all that crap, most of the troops on the ground don't know anything worth extracting.

    It might well survive, but would the person wearing it survive?

    Can't see the British army getting any new body armour in the near future, they're still rolling out the Osprey stuff to front line troops. I didn't even have plates in my 'old style' CBA when I was out in the hot and sandy.

    probably not mate but if it can take the frag at that range if you were further away from it your chance of survival improves

    A fair point. But I still wouldn't stand next to it and say "it's okay, I've got my body armour on" :p

    7.62mm will still do plenty of harm, apart from that, any self respecting sniper will aim off the plates anyway.
