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.

    Bit disappointing Chris that I can buy your MK4 Combro cheaper elsewhere (£42.99 collected or £47.99 delivered), thought it would have been cheaper going direct!

    Is the £42.99 one you have seen metric or imperial?

    Not 100% sure on the Mac, I think there maybe some software around but I wouldn't know where to find it. Someone on here might be able to help :)

    Not sure as I ordered it this morning and it arrives tomorrow, I would hope it's imperial as it's coming from a UK gunshop but i'll let you know.

    If you can let me know that's great. It could be a retailer that had stock from before we put the price up.

    Yes they will work with a Mac, contact gantongunner on this forum and he can supply you with the cable and downloads.

    i'm intrigued as to why you put so many pellets through your Combro in a string. I only ever put approx 10 to 20max. Am I doing something wrong or missing the point?

    Yes a shot string is usually 10 or 20 shots but, he said he gave it a bashing, perhaps in the excitement he got carried away? ;)

    chatting to grey skull and I think he has the answer.....the OP is testing the power drop over the full charge in a PCP possibly.

    The reason for the large/long string is that I had been adjusting the rifles internals to see the results of some experimental work.

    By testing a shot string between 100-190 Bar I am able to see the full "sweet spot" of the fill. It also shows me where along the fill that spot lies so instead of filling the tank to 190 each time I only fill to say 170 Bar which is where the "Sweet spot" starts.

    By doing this I also know where this starts to fall off and therefore know the point at which the rifle need to be recharged.

    Knowing this also means that if, for example, the "sweet spot" is between 170-120 Bar I can do shorter shot strings of about 5-10 pellets at 150 Bar for power testing and I know I am at the guns peak performance point.

    Shot strings of this length are only really necessary if you have made changes to the guns setup or perhaps changed pellets. Internal changes to the gun will change the starting/ending point of the "sweet spot" zone so I like to know where that is.

    On a PCP the Combro connected to a laptop is an absolute . send for doing this and for < £50 its the best value accessory I think you can actually buy for a PCP rifle.

    Here is the chart from the test I did:

    View attachment 92950

    This is on an unregulated rifle and the shot count and "sweet spot" is very good and fairly consistent for an unregulated gun, (IMO). This power curve was much less pronounced than the standard S400 setup which had a much less flatter arc before the changes.

    Interestingly these two pellet types give almost identical trajectories (in Chairgun software) and both pellets are comfortably within the legal limit with my non-anti-tamper S400's adjusted fully open so they cannot go higher without either a much heavier pellet or internal adjustment.

    I have since changed the setup yet again to make the rifle give me 11.3-11.4 ftlb with JSB heavies and about 10.5-10.6 ftlb with AA Diabolo Field. Have yet to do a full string through the rifle with the new changes to see the power curve.
