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.

Question Define a gas powerd gun.

    I have said it before and I will say it again being ill has left me with far to much time to think and hear is my latest nuget of wisdom.

    We group all gas powerd guns loosley as airguns be they powered by air or co2. So If we extend this logic then all guns are gas powered so all guns are air guns. It dose not mater if it is a small rimfire or a a huge cannon they all use gas to send the projectile out of the barrel. Place a round in a pistol and the bullet will stay there untill the powder is turned into a gas. The main diferance is the so called air gun is that the gas is allwase a gas and it makes the projectile move by compresion and expansion of the gas. The other type of gun uses the conversion of a solid into a gas trough the use of fire by a fuse a flint or percuson cap. Regardless of how its made it is allwase the gas that makes the gun work. Ok i must say sorry in advance but as i said i have a lot of time on my hands just now and I hope this will get some good reactions both searius and fun.

    Gas that is pre contained in a reservoir attached to the gun,not gasses already in the surrounding atmosphere.

    If I were being picky I would say that only CO2 powered rifles and pistols were gas powered; air is a mixture of gases rather than a gas, so that's my take on it.

    Does this mean my arse is an airgun?
    It has fired the odd projectile in the past. :)

    In that respect then, all guns are gas powered.

    They all use expanding gasses to propel a projectile along the barrel.

    The difference is what it starts off as - a compressed gas (air or CO2) or stored chemical energy in a rim fire round.

    An airgun uses natural atmospherical gas, compressed, to provide the energy to propel the projectile as the gas returns to it's original state.

    A CO2 propelled gun is a gas gun, but it is NOT an air gun. It uses a specific gas that is produced, not natural, ambient air.

    A powder burner uses a chemical reaction and HEAT to provide the motive force.

    So no, not all guns are gas guns. All guns might use gas to propel the projectile. The fundamental difference is that airguns and CO2 guns have an already compressed gas that is REDUCING in pressure as the shot develops. A powder burner uses gas that is INCREASING in pressure as the shot develops due to the heat of the chemical reaction.

    Hi Accuspell You are rite about the gas being under presure and the expansion of the gas propeling the pellet but only im co2 and PCP guns. A piston gun first needs to compres the gas then allow expansion before it can push the pellet out.

    Would my arse be classified as a pistol or a rifle?
    It's touch and go at the moment.

    I'd hate it to be found illegal and detuned or even worse destroyed. :(

    Air is not a gas. it's a mix of gases. whereas gas guns use a single gas....so a gas gun is not an "airgun"...but an "airgun" is a gas gun...rofl.

    NO. A piston gun still uses the compressed gas to fire the pellet in the same way - a PCP also has to have the air compressed before it can fire a shot. The piston gun simply does it for each shot in turn. A PCP has a number of shots done at the outset.
