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.

    Yes, up to a point. They won't be good enough for final zeroing but can get you close very quickly. They are also useful for checking that your scope hasn't had a bad knock etc once you know where the laser dot falls with a correctly zeroed scope.

    they are a complete waste of time and money.
    give me any gun and scope combo and I'll bolt the scope on and get the first shot on paper @ 100 yds using a plumb line,B&D workmate and a spirit level bubble cartridge

    Bought one a few years ago, used it once. They are alright for getting a starting point, but worl by assuming a perfectly flat trajectory.

    Pointless on an air rifle IMO.

    At best they only get you close to being zeroed.

    They are really designed for full bore shooters who want to save on cost and barrel wear, and on very large calibres the joy of extreme recoil which can become irksome after only 4 or 5 shots.

    Pellets are cheap, it should only take 2 shots to get in the same area as a bore sighter, maybe a few more if you can't be bothered to roughly work out how many clicks to move you POI and just twiddle the knobs.

    On a rifle with a removeable bolt it is fairly simple to boresight the rifle but not so with an air rifle. The laser boresighters are not likely to be perfectly aligned with the bore but they will give a fair idea of the projection of the bore out to a considerable distance. This should certainly get the windage sorted out and will also be fairly close for elevation at a normal air rifle zero range. Once the rifle is properly zeroed you can then replace the boresighter and, at a known range, compare the laser dot to the reticle which will give a better guide for future use.
    One of the problems with the boresighter is that if you rotate it in the bore then the laser dot is likely to move in a circle around a central point, if this circle is greater than a few inches at 30 yards then you would have to be careful when using it to make sure that either it is always put in the bore in exactly the same place or that you rotate it through a whole circle and use the central point as your datum.
    I would only use one if it were not possible to actually shoot the rifle as it is generally easier and quicker to zero by shooting first at close range (to ensure that you are going to hit the target), get an approximate zero and then move steadily further out until you reach your zero range.

    I wasn`t aware that these were available for airguns/guns with non removable bolts until I just googled it:eek:
    my previous answer only related to rim/centre fire guns:up:

    I've got one of these laser bore sighters and as Terry said they do save time on initial sighting in meaning you only need to fine tune the final adjustment by a click or two.They're not that expensive either I bought mine off ebay and I think ii cost about £12.99 ,does .177 & .22 plus other calibres.

    I am puzzled by the statements of a 'flat trajectory'. Even full power FAC rifles do not have a totally flat trajectory because eventually the projectile drops to earth in an arc. My duties as an armourer whilst in the forces taught me that.
    I now only shoot air weapons but I always use one at the distance I usually shoot at (35m) and since I stared using it have saved loads of wasted pellets and targets. No more hours spent walking backwards and forwards, no more wasted pellets or air and no more tired arm with cocking a springer! Set it up, use it and a few shots after that to see where the pellets land, the final fine tune if it was little out and its job done. They are a great time saving item and everyone should buy one for the little they cost.

    Don't think you will be disappointed. Have found it particularly helpful when first trying to zero a gun with pronounced barrel droop. Over the years have saved myself loads of pellets as I enjoy trying different scopes:)
