  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.

Question How "normal" is losing zero on scope?

    Hi,
    I am sure that there are many factors on why a scope loses zero but wanted to know about your experience because I am getting a bit tired of mines...
    At the moment I am using two scopes permanently attached to two different guns:
    Simmons WitheTail classic 3.5-10x50 on a TX200 .22 and a Bushnell Trophy XLT 6-18x50 on a HW80 .22
    I know they are not top quality scopes but I would expect them to maintain the zero.

    I hunt rabbits from time to time but almost everyday shoot a target on my garden at 35 yards. I am a bit frustrated with the zero keeping of my scopes. I zero them and after about 50 to 100 shots they lose zero. It happens from one day to another; when I start shooting the first shots get at about 1 to two inches from the aiming point and I have to re-zero again. This will last again for few days.
    I find weird that the lost is so abrupt. I would expect it to be gradual from shot to shot.

    The question being: is this "normal"? Could it be the cause changes in the spring? I have the normal mounts; Would it improve if I put good mounts (leopold)?

    Many thanks for any advise!
    All the best,
    Adam

    Hi Adam,

    Do your mounts have a arrestor pin? (Ta barca)

    If so are you using it?

    Are any of the bolts holding the Scopes to the mounts or guns coming loose? Are you having to tighten them?

    No1 suspect would be the mounts. Check they are tight. Cheap mounts on a springer without an arrestor pin is asking for trouble.


    And those scopes are good quality not cheapo scopes.

    Thank you for your replies.
    Yes, the mounts have arrestor pins and I use them. They are definitely not good mounts; bought for less than 20. I check the bolts and are tight though.
    So, I guess by your replies that it is not normal then.
    I will try first changing on gun's mount. Any advise on mounts?

    If it's a springer, then the first few shots will be different to the rest of the shots. Take a gun that has stood a while and chrono the first say 5 shots and then watch what happens to the shots afterwards, they always seem to creep up on power as the lubes gets stirred up and those internals that haven't moved for a while settle in again (especially the seal). Not only will the poor differential of the first few shots make a difference but it will also affect the recoil characteristics slightly and thus affect aim/zero.

    Try a Sportsmatch one piece mount. Others may recommend BKL mounts too.

    Well; I have followed some of your advises and, although I had mounts with arrestor pin, I ordered a Sportsmatch one piece mount that I have set up in the TX200. Two things:
    When taking out the two parts mount from the TX200, I noticed that the orifice where the arrestor pin goes was ovalized. That much recoil this thing has...
    As a note, the pin in the SportsMatch doesn't seem very positive, although phisics says that a pipe section bar has far more resistance to bending than a solid bar... let's see, but the ovalized orifice is a bit scary. At the moment it has gone throught three days of shooting and the zero is there.
    The Bushnell scope has gone for repair in warranty! It did not only lost the zero but the focus as well! All has moved inside. Don't know what to think... it is not cheap scope.
