  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.

    I'm putting a variation in to my local Firearms department in the next two months for a .223 and mod to be used for fox control. I'm also considering applying for FAC air but not really certain of what calibre to apply for .22 or .25. What are the pros and cons of each?

    Got both mate, both a good tool been playing around with the recent .25 acquisition
    In my eyes .22 has greater scope of ammo choice and .25 although a bit more limited (but catching up I think) has the edge for energy retentions at range especially with slug etc

    Both run 900/1000fps. 22 uses less air to do so. I on 22, both play by 100yds if u no the art. I hit a shotgun cartridge 3 out of 3 Sunday at 90yds. Then the wind and it sat in line took a few to hit it again, so shows wot a 22 will do.
    Still doing more that 12ft at 100yds.
    More of take your pick. ;) al

    I've got the Impact in .25 flavour, absolutely awesome pest control gun - it just kills, no twitching or jumping about as long as you do your bit of course.

    Just ask for a .22 with a .25 spare barrel (or vice versa), then a Crown or IMPACT will do both very easily!

    To me, the argument for .25 over .22 FAC in the UK is much the same as .22 over .25 in sub-12. There's little point... not even the logic of minimising pass through at short range. If there were other legal quarry that necessitated the extra energy of the .25 it would be a different matter. As it is, you have to go up in power and air consumption to get the same trajectory and, at the range limits, the biggest uncertainties are accurate ranging and wind estimation, nothing to do with the calibre per se.

    The speed of sound is 1125 ft / sec. USA folklore which is probably correct says you don't want to go there with pellets as they aren't stable enough.

    When the Career 707 was being sold it could reach that level in FAC and heavier pellets were also bought in for it to keep the speed down. I was told that in Korean form it was 40ft/lb in 22 but a local dealer reckonned his was 60 - probably with lower weight pellets.

    So I would say choice depends on the power of the gun and the pellets that are available. Do some sums. In the USA people can buy these

    For me it's difficult to justify FAC air over .22LR.

    So you want to keep it fairly different to the . 22LR so it has a clear function. If .22LR is too much gun- the FAC air has a place. .22Lr is around 100 ft lbs with subs.

    I would want a flatter trajectory than .177 12ft- but use .22. So perhaps 30ft lb would be nice. Point and shoot out to 40 yards or so.

    .25 will warrant more air per shot unless you sacrifice the trajectory a little. Plus fewer pellet options.

    I was lucky enough to have shot both .22 and .25 fac air before making my decision. .22 at 30ft hits hard but .25 at 46ft hits ALOT harder especially if you use 33 gr pellets. .22 wacked the spinners but .25 destroyed them snapping the heads off 3 mm thick steel ones. Apart from more air usage the .25 has no downside for hunting for me. Effective humane hunting at upto at least 80yds is possible with both calibers.

    If I could have only one it would be the 25 cal as it is amazingly versatile and allows me to creep into rimfire territory without the noise of an hmr and the ricochet worries of a 22lr. Also if you have big bear paws 25cal pellets are that much easier to deal with..... Having said all this I have a 25cal and 22lr and 22 fac airguns so clearly I am not fussy.

    Please forgive me if this is a daft question, I’m considering applying for FAC certificate for a FAC Air rifle and I’m reading up on the Impact mk2 PPlenum in either 600 or 700 Sniper. In regards to the capability of the two calibres was the .25 at 46 FPE a pretty flattish trajectory?
    Thanks

    @rbov depends what pellets you're shooting. With jsb kings the trajectory at 46ftpe will be flatter than a sub 12 177, with the 33 grain heavies probably on a par. The thing about the impact is that, at fac levels, you can change the power very easily to pretty much whatever you want. This means it is easy to hit 900ftps with any pellet you chose or indeed faster speeds with various pellets and slugs. I shoot heavies at 850ftps then drop down the power wheel to four and shoot kings at 890ftps with the regulator at 105bar. Works well for me but you could easily chose to shoot the heavies much faster, the world's your oyster.....

    Yes its a lot flatter than .177 and the speed means the time between pulling the trigger and hitting the target at sub 12 ranges 50yd the impact is almost instantaneous! Another advantage of .25 is the pellets are considerably heavier ie 16gr verses 25.4 or 33.4grn so wind age is very slight. I remember shooting my mates .25 loaded with 25.4grn at a target i was at the time using my sub 12 10.34 grn .177 and holding off the 50yd spinner by 2 inches to hit it in the strong breeze. I asked how much should i hold off and over? He replied dont just aim straight on, it worked and the 1 inch spinner spun around at high speed.

    Thanks Keithy. Sounds like .25 is a very capable calibre at FAC power levels.
