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.

    Am I missing something? My BSA Ultra with a Blast Tamer I fill to 220 Bar and it hits the mark from there to 100 Bar I calculate that it uses 2 Bar per shot and therefore gives me about 60 shots and yet that is far more than advertised! Any comments?

    Almost correct depending on how you look at it..

    If your getting 60 shots on target then that’s a plus, but the chrono may shed some light also

    What is max pressure on the ultra? Me and my son only fill ours (an se and a mmc) to 190 bar. Just thinking if you put more air in, youd get more shots out?

    60 shots sounds a bonus, but as said, check the figures on the chrono for those 60 shots to see what the spread is....although if they are on target they are all doing the job.

    Thanks

    Thanks for your reply Tim. Chrono say's there is about a 15 ft sec variation. I am just amazed that I get this shot count from an unregulated Ultra!

    Excellent! Try bringing the target in to about 15 yds and you may get at least another 20 shots!:laff:

    Did you log the numbers Simon over the string? without having a regulator there would be a sweet spot where the variation remains quite low (in theory) - would be interesting to see how close to 60 this was.

    Thanks

    My .177 ultra se has a huma reg fitted,from a 230 bar fill with unweighted pellets I get 45 shots before it drops off,each shot is within a single fps of each other and an overall spread of 10fps over the 45 shots.i was expecting to get more shots but you don’t you get a better shot to shot consistency and therefore don’t have to find it’s sweet spot

    180 down to 150 but no noticeable difference to the POI through out, this is why I was so surprised!

    250bar fill (JB Blueprinted) and HuMa regged, I get 80+ shots per fill in .177, sweet spot from shot one until the pressures so low it won't spit them anymore. ;)

    The only way I’ll get that many shots from my se is by fitting a scorpion cyclinder

    I sold my .177 Ultra last autumn. I had replaced the standard 175m cylinder for a 250mms unit. That, together with a blast tamer gave me 58 good shots. I used to fill to 190bar.

    Sounds like it may be running at a lower power than being in the 11’s

    One of my regged ultras ran at 10ft/lbs and had a surprising amount more shots per charge at that power ....

    Hi Mikey,

    Sometimes I have to give myself a check and remember what these Ultra's are like out of the box, unregulated and untuned they are mediocre guns but when you have them tuned and regged they jump into a whole different league, of what you'd expect from something costing a whole lot more. (Hw100 territory)

    I like the Ultra so much because they are comparatively easy to work on and not badly made at all IMO, I think after 2015 or 2016 that all changed though.

    The lasted incarnations from Gamo.... nah! no thanks!

    I’m not sure the exact shot count I’m getting but I reckon 40ish on a 225 bar fill at 11.4 ftlbs (.177 ,heavy pellets) ☹️ Before I see the power start droping off.
