  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.

    As many of us know Air Arms are the sole official importers of a limited range of JSB branded pellets (.177 Exact @ 8.44gn and .22 Exact Jumbo @ 15.9gn), while also marketing some of JSBs wider range under their own name.

    While not exhaustive, below is a list of the most appropriate JSB offerings (in each calibre) for our market; as well as the equivalents offered in an Air Arms tin:

    At first glance it seems that AA have the range reasonably well covered, however in .22 IMO the 14.3gn pellet represents the "sweet spot" for 12ftlb rifles - the two heavier offerings being too weighty for springers and arguably for anything at our legal limit (ideally). Conversely, the Falcons are a bit on the light side..

    Having recently had the misfortune of being begrudgingly involved with some .22 rifles, the escapade has highlighted to me a stark lack of decent, middle-weight (14-15gn) domed .22 pellets. RWS Superdomes are reasonable quality but have similar drag properties to a caravan fired sideways, H&N FTTs seem to be somewhat variable while the quality of Crosman pellets seems to be ever-decreasing.

    JSB have pretty much monopolised the .177 pellet market (and rightly so) on account of their usually excellent quality and performance. While the 15.9gn Fields are undoubtedly popular, it seems strange that Air Arms haven't seen fit to further capitalise on this success by offering the 14.3gn pellets as well. Anyone else feel the same?

    Of course, we can always stick two fingers up at Air Arms by buying proper JSB's from Intershoot in Ireland - however unfortunately they're currently out of stock of the Express flavour in .22 :rolleyes:

    I was just about to order my usual jsb express, my rifle loves them!

    The tin I am currently using has too many badly damaged pellets, which is unusual for jsb/intershoot!!

    To save some of the pellets, you can always push the head of one into the skirt of the damaged skirt. Intershoot normally well packaged, as are BAR

    Funny, I've never noticed it until you commented. I have only tested the .177 which will be a bit different to the .22 but yes you are right, it does have a high drag coefficient for some reason. Maybe I should look at why it should be like that sometime.

    The Exact Jumbo Express is an excellent pellet, soon to become my default pellet of choice for .22. Requires a quality moderator/stripper for accuracy though. It took me a long time to find something close to the performance of AA-Field, with a flatter trajectory.

    Unfortunately, I am finding the supply of Express and RS in .22 very low. BAR have been out of stock for ages. Voymir has run out of RS. I got the last of the Express from Intershoot.

    I've got enough for the next 6 months, I hope the suppliers get more stock in.

    Cheers chaps :)

    Aye, only problem is that they don't sell the Express in .22 - I think they're only retailing pellets they can obtain through "official" channels.


    Thanks :)

    Tbh I've not noticed much of a difference - the price of "officially imported" Exacts and their AA branded equivalents is the same at around £9.50/tin in .177 and £12.50/tin in .22. "Grey" JSBs from Intershoot are often noticeably cheaper though; especially when you consider that postage is included in that price.


    Aye.. I strongly suspect it's down to their head shape - the dome is shallow and has a very large radius. Compare this to the AA Field in .22 (which appears to be an excellent design); the dome appears to be almost a complete hemisphere; the tangent of the dome's curve at the base of the head is almost parallel with the longitudinal axis of the pellet, if you see what I mean. Due to the angle at which the air is travelling (with respect to the pellet) when it separates from the head, I suspect this shape creates a smaller wake behind the pellet in flight and hence less base drag.

    With respect to head shape the AA Field is far more of a "true" dome design; while the Superdome is more like a halfway house between a dome and flat point shape. Indeed, the typical BC figures doing the rounds on the 'net place the ballistics of the Superdome very close to those of the completely-flat Hobby (around 0.016 v 0.011) and that's not taking into account the additional mass of the Superdome (around 3.6gn or 35% more than the Hobby). Based on these figures I suspect the drag coefficient of the superdome isn't much less than that of the Hobby.

    In the week I did some quick and dirty chrono testing with various .22 pellets. From a muzzle energy of around 11ftlb, at 50m the Superdomes only had around 4ftlb left while the AA had closer to 9ftlb (don't take these figures as gospel, but they've got to be reasonably indicitive). This was further backed up by the fact that the AA pellets were silent in flight, while the Superdomes displayed a very audible hiss as they travelled down range - highlighting the amount of energy being lost through drag..

    Air Arms not missing opportunity - With the Choice of Pellets out there it's not worth the Effort to Launch more

    While Shooters are able to get them under Different Labels and Distributers

    There is a Limit to what Most Retailers / Mail Order Houses can carry as Stock -

    I'd disagree with this - Air Arms have a contract with arguably the best pellet manufacturer of current times; all they apparently do with much of JSB's range is badge them differently and punt them on. It seems to me that distributing JSB Express under the AA banner would only require some new tins and some altered logistics - none of the time and expense spent developing / testing / manufacturing an entirely new product.

    AA choose to bring in many of JSBs other offerings (under their own name), yet miss out arguably the most potentially popular weight. There's not much competition from branded JSBs Express pellets as these aren't officially brought into the UK by AA (and are only available as grey imports through two shops that I know of) while AA have an entire, established distribution network at their disposal to sell such an item.

    As for decent JSB alternatives at 14-15gn - as I posted originally - I see very few (i.e. b****r all) of comparable quality or performance..
