    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.

    Excellent article on zeroing.
    A lot of emphasis was placed on getting the recticle vertical, when i hold my rifle comfortably the weapon leans slightly to my right and then the cross hairs are tilted clockwise. Should i get the crosshairs level/vertical by lining up with known plumb object with the gun plumb or with me holding it comfortably or is it personnel choice? I hope i have made myself clear. I am a newbie to this site and am loving the feel of it compared to other sport forums.
    Thanks
    Archie

    If zeroed at ten yards, what's the drop/rise of the pellet from ten to thrity yards in .177 at 12ft/lbs or is that dependant entirley on the rifle?

    It's dependant on the pellet type and muzzle velocity.

    Great thread on zeroing scopes.
    Wondering if anyone has come across the same problem as I’m having, bought a cheep 4x28 scope for my DB4 Underlever. The problem I’m having is it’s shooting 3in below target and 3in to the left and that’s with elevation and windage set to their limits. It’s power seems constant pushing every pellet through a yellow pages with the point protruding from the back.

    Can anyone advise me on how sort the problem or is it a case of reap what you spend.

    Here's another zero method if anyone would lie to try it....

    Set up your target at 25 yards/ metres. Fire a 5 shot group at the target keeping the same point of aim for all 5 shots (please do not be tempted to "chase the shots" otherwise it will not work)

    Retrieve the target and with a ruler try to draw a cross [X] from the extreme most verticle and horizontal shot holes. If this is impossible, box the 5 round group in, then draw the cross from corner to corner of the box. Where these two lines cross is the "Mean point of impact" or MPI.

    Measure the distance from the MPI to the centre of the target and adjust the scope as neccessary: Most scopes = 1 click is 1/4 inch adjustment at 100 yards so quadruple the number of clicks for 25 yards. (Say for example you are 1 inch left....you will need to adjust 16 clicks right at 25
    yards :up:)

    You will also need to measure the distance from the two outer most shot holes and divide this figure by 4. This will give you the permissible variation (PV)

    That done............... set up another target at the same range and fire another 5 shot group keeping the same point of aim for each shot. Retrieve this target and do as you did before to find the MPI. Measure the distance from the MPI to the centre of the target. If it falls below, or within the figure you recorded as the PV the rifle is zeroed :D.

    Maybe your scope needs shims, take off your scope and look at the mounts, this is really the first job you should do before mounting any scope. ensure that the mounts sit square on the scope rail.:up:

    I must admit i use this method to. I found with PCP's this is the easiest and fastest way that works.

    Its a little harder with springers due to cocking etc but for CO2 and PCP its great.

    Good Find Lonesome. :up:

    Having only ever shot over open sights, found the info on zeroing very useful. I am picking up my TX200 HC and scope tomorrow so this will be a great help to me, cheers.:p

    I'm lucky in that I've got an end wall of a pub which is painted white about 40 yards away which is useful for scope setting. It has a tall chimney which provides a fairly accurate 'plumb' vertical reference so I can line up the vertical crosswire with this and rotate the scope till the crosswire appears to cut the cylinder exactly in half. The white wall provides a bright surface for adjusting the eye bell to bring the crosswires in focus and to adjust eye relief.

    On the first page Andy mentioned about zeroing with a piece of string. Could someone explain in further detail how to do this please.

    If you hang a piece of string with a weight on the end. Looking through your scope at the string will tell you if your scope is level if the vertical hair isn't alined with the string your scope ain't level.;):up:
