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. No longer allowed 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- We now do not allow political and religion threads anywhere on the forum (including the Adult section) unless Airgun related and they must be put in the Airgun related politics section..

    Staff will not move posts for you if you put it in the wrong section – it will simply be deleted. You will then have to type it all out again and put it in the right place, so heed this warning.

    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.

    I got a Brno 511 yesterday and tried to zero it tonight, well it didn't go well:mad:

    I have a Pulsar 550 and tried to do one shot zero but didnt work at all.

    I used a board about 2 foot wide but 4 foot high, placed it 60 yards away and couldn't hit it. Moved the board to about 25 yards and hit the board :) but if I move the ret to the poi I can't hit the board again.:mad:

    Shooting off a bipod and rear resting on a block so rifle is steady.

    Any ideas what I may be doing wrong?

    Is the gun well used? Check that the barrel is clean and straight, are open sights fitted, if so try the rifle with those. Is the scope/mount combination tested before, its just a case of eradicating variables and checking each item in turn. Also which ammunition are you using, as some semi automatics can be a bit fussy.

    So if I read this right, you hit the target at 25.... then set the crosshairs on the point of impact, re-centred on the target then missed the target.... as 1961 nuffield says it's about getting rid of the variables... first check the scope mounts are tight, both on the rifle and scope no movement, next do a test fire of about three into the target see how the rifle groups this also helps evaluate the ammo, then move the crosshairs into the centre of the group, again fire another group of three see if this group is better, repeat until your happy... you may thing your using alot of ammo but sometimes it better to waste ammo now getting it right, rather that spoil a card or miss prey at a later date. If your still not happy after about six goes try another type of ammo..... btw what ammo you using?

    i have a pulsar n550 but never had a problem zeroing it . however i dont use the one shot zero as you cant see the impact point through the scope. i just aim at the target fire a shot have a look at the target and adjust until its bang on. normally 10 shots is more than enough. if your mounts are tight and the rifle is ok you you shouldnt have a problem....check the rifle with another scope or the scope with another rifle ....hope you sort it mate ...matt

    I have a BRNO 581 which is identical to what you have, if not the same thing. There is no such thing as a BRNO 511 as far as I am aware, although I may be wrong, it's either a BRNO 581 or CZ 511 (CZ were the parent company of BRNO I believe and used the 581 as a copy for their own version, the 511). That's why many of their parts are interchangeable. I had a problem with zeroing mine as well. Importantly, are you using subsonic rounds? Also, mine was fixed with a thorough cleaning and oiling of the barrel.

    Thanks for the advice, sure its the rifle as I can't get it to even shoot in the same spot even twice in a row. Spoken to the dealer I got it from and said bring it back and will give me money back.

    Oh well on the look out for anouther semi auto again.

    As abouve it will be the CZ511 if it has a heavy barrel. As with all CZs they like to be clean and they love Eleys and Winchesters. Have you tried resetting and centring your scope on a mirror somtimes that can help. Also every time you move the windage or elevation give the turret a light tap, sounds mad but if its an old scope they become loose and can move a tiny bit on first recoil but are fine after that.

    Download the Hawke Balistic Calculator if you are looking to do your one shot zero as you input your variables and it tells you a fairly accurate near and far zero and also the variation on the bullet on its travels

    Funny you should say that.:D

    I took the rifle back and got my money back, felt a bit sad as I don't like giving up.

    I then went to my local RFD to stock up on some rounds and he offered me a stainless Ruger 10/22 with synthetic stock for £25 pound more than the Brno:D

    Now why didn't he tell me he had that on Friday when I spoke to him.

    Just wish this wet weather would take a hike now so I can go out and play.

    aint cleaned mine in nearly 2yrs, and still spot on 60yds

    theres many home mods you can do with the ruger, the one thing I found to be a pain, was having to push up the button in front of trigger to release the bolt, sometimes took me 20-30 attempts, theres clips on utube on how to modify the internal catch, so simply pulling back the bolt releases it, if you end up wanting to do this mod, let me know your address, I have a spare internal release thats already modded, save taking a file/dremmel to yours
    these rifles are so easy to fully take apart its a joy:up:

    I took the Ruger out last night and it took 2 shots to zero the pulsar 550 :D, tested 8 shots after that and its just shooting to the right:), will fine tune this later.

    Did get three rabbits after the zero though.:D

    How did you swap one for one like that? Did you not need your slot opening back up after selling the first gun. It's a long time since I swapped one for one but I am sure that is how it works. Cheers Andy

    as the rifle was purchased on the 1st, and returned around the 3rd, I would imagine the gun shop hadent sent details through, as its within 7 days, they probably wait untill end of each week then send all paperwork through, on the certificate it may or maynot state semi, but its then a simple fix for the shop, to cross one out and fill new one in

    I had not done the notification yet and the gun shop had not either, he just cancelled it on my ticket and booked the rifle back into his stock.

    As Pestie said cross out and redo.
