  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.

  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..

Question about BSA Ultra SE Multishot in .25 Cal

    Hello from the US, I recently ordered a BSA Ultra SE Multishot in .25 caliber from Pyramyd Air and have a couple of questions.

    I believe its a 12 ft/lb model, its doesn't specify and believe it or not the guy on the phone had no idea. It's quoted firing .177 @ 820 FPS, .22 @ 570 FPS and .25 @ 500 FPS.

    I will be shooting rats, squirrel, possum and pigeon sized game and plinking at no more than 20 yards.

    My questions:

    1-Does anyone have one of these in .25? Or a similarly powered air rifle in .25? If so can you comment on it's effectiveness at 20 yards and less?

    2- It's quoted at 45 max shots per fill in .177 cal and 55 max shots per fill in .22 & .25 cal, shouldn't you be able to get more shots per fill with the lighter smaller pellet?

    3-Am I better off changing my order to a .22 cal version, I've read so much about the horrible .25 cal trajectory and suck at using Chairgun.

    again,
    I will be shooting rats, squirrel, possum and pigeon sized game and plinking at no more than 20 yards.

    Any help will be appreciated.

    Thanks!

    20 yards and below,trajectory shouldn't be too bad ad the pellet isn't going to tail off as bad,I wouldn't worry,have fun with it :)

    Less shots with lighter pellets because they need more air to get them up to speed. All calibers will do the job, but its just a case of learning the hold over/under for a specific caliber. .177 will fly pretty flat out to longer ranges, .22, and .25 will need a bit more use of the mildots on your scope.

    Sub12 at sensible ranges, all will do the job nicley:)

    The SE is very easy to adjust to get more shots and a flatter power curve AND to increase the power IF your law allows it.
    PM me if you need any details.

    I've got a .25 scultra which is a scorpion se and ultra combined to make the best gun,you won't have a problem with 20yrds pest control,I moved on From .22 to .25 for my rat shooting about 2 years ago.you can't beat .25 for hunting close range.absolutely devastating.none of that rat running off stuff.takes half there head off.go for it.ive hunted rats at 25yrds before with no problems.

    Im on the hunt for a .25 calibre rifle but havent really been tempted by BSA because I had read somewhere that they arent actually .25 the are slightly smaller so can be pellet fussy and most people recommend a .25 pellet sizer for .25 in general but definitely so with BSA. Not got an issue with BSA though had a few of their rifles and never had any problems or complaints I was just thinking that it may be better to just get a .22 and use heavy pellets.

    It might be a good idea to turn up the power a bit since you are in US, around 600 fps with H&N FTTs would be quite perfect for the range you are stating.. If you want you should be able to make the gun shoot about 800 fps but that will drop the number of shots considerably.

    H&n shoot at 500 fps at sub 12 powers not much diffrence to a 16 grain 22 jsb kings 440 fps you can still stack pellets at 40 yard with heavys and take all small game /vermin but as your in usa u have no need to keep it at sub 12 powers

    Career707lover.i haven't had any problems with pellet sizes in my scultra,used bisleys and bsa interceptors mostly but I have tried some obscure makes from ebay and had no problems.the difference between .22 and .25 is massive.you won't believe the differance until you've tried both side by side which I have.my gun was built by Derrin from xtx and it's unbeatable for ratting.

    BSA's ".25" barrels used to actually be .243, hence the need for pellet sizing etc. I believe that this has now changed and that the current .25 barrels are a true 6.35mm. I had an old one which I bought from Knibbs (it was NOS) which required sizing but have shot newer ones that will shoot most .25 pellets straight out of the tin.

    Thanks for the info guys I didnt realise that the BSA's were actually "real" .25 calibre barrels now. I always fancied a Spitfire or even Lightning in .25. I think the guy I knew who had pellet issues was using a Supersport in .25 and it was a few years ago now.

    I can confirm, it's been a while that they've put out undersized .25 cal barrels. Anyway guys I ended up going with the .22 cal, I can just shoot heavies out of it.

    thanks, i was hoping a lot more chimed in and this thread got a lot longer, i would have loved to read more of those experienced in 12 ft/lb .22 and .25 cal hunting but then i'd be taking away valuable shooting time from you guys :)

    I use an ultra in .22, I hunt rabbits out to 35m sometimes 40m if the condition are in my favor, puts pellets within a 5p bit (18mm) shot after shot. 14.4g jsb exact express, puts rabbits down without a twitch no problem. With sub12 its all about shot placement, if the target is hit with a light or heavy pellet in the right place, its going down.

    Use the pellet that's most accurate, light or heavy:)

    Got my in my BSA Ultra SE Multishot in .22. The dealer ran 10 shots through a chronograph, 11.9 grain RWS Hobby pellets were 611-616 FPS or 9.86 to 10.02 FPE, according to them they filled it to 3200 PSI. I know that 12 FPE in the UK usually means sub 12FPE. I'm not looking to turn it up that high but would like to get at least the advertised 12 FPE or 13FPE
    It's filled to 125 BAR and I just ran 10 shots through my chronograph using 14.3 grain Crosman, I got 485-510 FPS or 7.3 to 8.2 FPE. I really don't know PCPs too well, how do I get closer to 12FPE? Do I have a bad rifle? Thanks

    Hey guys forgot to mention I don't have a pump, I was shooting it with the air it was shipped with from the dealer. According to them they tested it at 3200 PSI and got 611-616 FPS or 9.86 to 10.02 FPE with 11.9 grain pellets. I got it shipped to me at 125 BAR and shot 10 shots and got 485-510 FPS or 7.3 to 8.2 FPE using 14.3 grain pellets.

    Discussions on how to adjust power aren't allowed on the open forum. It's possible that someone will be able to point you in the right direction via pm. I would suggest that you need to shoot s few hundred pellets through it before you start worrying about making changes - happy pumping! Do you have access to a dive bottle, that's the simplest way to do it?
