  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.

    Crossman 14.3 or Accupell - no problem about damaging the gun. FTT would work at that velocity too. It isn't like you are whacking them out out 980fps.

    In my Rapid .22 fac running at 28fpe, I use Air Arms Field Heavy, 18gr which produce superb groups and drop live quarry with ease. At only 16fpe, a standard AA Field at 16gr would be my start point and I would also test pellets such as JSB RS which while lighter still are very effective.

    Just as a matter of interest, I am only using AA Fields, 25.3gr in my FAC Impact .25 running at 47fpe with great results hunting.

    Test loads, learn loads.

    Which rifle mate?

    I've got two springers (FWB 127 at about 13.5 and Diana 350 at around 24) and they both work best with average weight 14gr pellets.

    You gain nothing imo from going heavier, and generally get less energy and a slower shot cycle. Kodiaks for example are too heavy even for the Diana which brings when firing them.

    Crosman Premiers and Premier Magnums, JSB Exact, and H+N and RWS in the 14gr range.

    Tbh at that modest output I'd expect any of the usual suspects to be fine - even 13.43gn Exact RS would only be motoring along at a leisurely 730-odd ft/s at 16ftlb.

    More to the point, why are you wasting your time and filling an FAC slot for a meagre 33% hike in energy over the legal limit? In the real world a 16ftlb .22 springer is unlikely going to give you any additional range over a a 12ftlb equivalent; especially if that 12ftlb rifle was a .177 PCP..

    I don’t know about springers but JSB RS at 900 FPS are “bang on” for me

    16fpe isn't worth having in my mind I believe fac min should be 26fpe and with a good pellet it becomes pinot an shoot 95% of the time no need for old over thinking of adjustments etc etc, so if I was you I would 're evaluate your needs for the gun, put it back down to sub12 being it's a Springer I find my old Springer work best at 10.7fpe using 14g h&n pellets, for fac you really need pcp with buddy bottle to give you average shot count, then you can run 40fpe plus with like of rapids the s10 full length version and still get good air usage,

    am changing it to gas ram and will see where it 'sits' powerwise then. i imagine will be around the 14fpe so will be much like a 12fpe when it comes to pellet choice

    back when gas rams first started being used you could put a 177 in a 22 and it's would run 15s, but these days they done the maths and it don't work like that now, with a ram you'll find the gun smooth to handle, Blackpool air rifles did them for 80 sobs last I looked, I've got a spare ram kicking about as when I was finished with rams I decided to convert it back to a Springer and test my skills to see if I could better the ram, guess what's still in Springer, YEP the spring. that doesn't mean don't get one it's the opposite buy one as a shoot they work well, for me it's tuning and testing boundaries new and old, then I compared my to my old Wembley venom. one thing I will say is rams ain't kind to crappie scope mounts and scopes so but the best one piece mount you can find or dampa mount

    my ram is coming from South Africa where a guy , sadly passed away now, specialized in tuning these gamos and had rams built to order. Am getting one of those.

    can get it from 580n up to 640n. apparently 580n is the sweetspot. lets see.

    i will still be doing all the de burring and polishing etc. and while the piston is out will spend time fettling that and then do the comparison.

    I do have dampa and bkl one piece mounts already. have a sidewinder and a m18 Falcon will see which fits better

    sounds like your getting it sorted, my ram was one of the originals from a gunsmith in Bedford area that helped the Cambridge boys, there been around for some years now. I BeLeave in Bedford area the company awd still is going they made direct replacement units, I must admit I've seen it all in every shape or form but when you handle a perfectly tunned springer you'll know the difference, as I built to identical Wembley xocet first was tweaked gas ram version the other was fully tunned springer, when I past

    them around my friends they couldn't believe one was spring powered they could BeLeave it,

    If jsbs at 16gr are too light and Bisley Magnums at 21gr is too heavy why not try BSA Blue Star at 18gr? They seem to be pretty accurate out to 35 yards in a sub-12 fpe (info from Airgun Shooter magazine) so that extra bit of 'oomph' might be OK.

    I don't think that there would be any issues with any standard 14-16 grain pellets at 16ft/lbs. What ever the barrel shot best before should continue to perform.

    I've used Premiers up to 1080fps, 14g Sovereigns, 16 and 18 grain AAF / Exacts up to 1000fps so at 680-700 your choice is still fairly unlimited.
    I'd say maybe headsize might be a a little more critical.

    obviously shooting a PCP at 40ft/lbs+ and longer range shows up the difference between brands and sizing but if you want to lob artillery rounds I think jsb is the way to go.

    I found BSA reds awful over 30yds and at 15yds my sub-12s wouldn't group with them either. Straight from the tin they are slightly better quality than GamoTS18 and Proshots but not much. I think they are the same but with a different factory lube.
    The skirts are really thick and hard to seat, maybe ok in a 24ft pcp with a moderate choke but otherwise thumbs down from me.

    AA Fields or Accupells at 14.3gn are plenty man enough for 25ft-lbs. Not tried them any faster but I don't see why they wouldn't take it. One way to find out!! :D
