fruity Posted January 13, 2012 Report Share Posted January 13, 2012 What power is it at the minuite ? Quote Link to comment Share on other sites More sharing options...
Hamster Posted January 13, 2012 Report Share Posted January 13, 2012 You don't mention the model, my guess is it may well be one that's hard to get running close to the legal limit accurately enough for serious vermin shooting. A half decent service or mini tune up would cost somewhere around the £50 mark, unless you want to use this particular rifle for sentimental reasons I would say you're better off investing £200 or so for a nice 2nd hand hardware including scope .

I would agree it would be better to buy a nice used rifle from a dealer, that way you know that its under 12 ft lbs, its a prison sentence for being in possession of a firearm without a ticket, in air rifle terms if your rifle is capable of exceeding 12 ft lbs with any projectile then its a firearm. So you rebuild ot with maybe anew spring and washer and you might be in serious trouble. Assuming its an older rifle ( a picture would confirm) then Meteor which is really a beginers gun and ok for a few close rats wont get anywhere near 12 ft lbs. Mercury which from memory was a break barrel was a good tool as was Airsporter ( underlever with loading tap) . Still got a 177 airsporter myself. Both mercury and airsporter are capable vermin performers, do 10-11 ft lbs usually. The sight ramps are very shallow so get a GOOD set of mounts for them otherwise they will slide off the back. Whats good these days god knows, in my air rifle days it was Sportsmatch and Theoben. Older than that, then still good performers and worth getting them done up properly.

ordnance Posted January 13, 2012 Report Share Posted January 13, 2012 Its hard to get more power out of a spring air rifle without ruining it, unless done by a professional at a cost. Quote Link to comment Share on other sites More sharing options...
Livefast123 Posted January 13, 2012 Report Share Posted January 13, 2012 (edited) The Supersport is a decent bit of kit and will be capable of power close to if not over the legal limit if you are not careful. I would get a standard tune up kit for it, strip it, fit the kit, re lube and see where you go from there. Around £72 from - http://airgunbuyer.com/Showproducts.asp?cat=Accessories&SubCat=V-Mach%20Rifle%20Tuning%20Kits Make sure you have access to or buy a chrono to check power readings.I've just rebuilt my PCP Falcon FN 12 and on running it through the chrono the first reading with a 14.2 grain pellet was 13.51 ft/lbs :blink: que some rather quick adjusting to get it back to a far more legal 11 ft/lbs. Apparently lighter pellets give more power in a springer and the opposite in a PCP Edited January 13, 2012 by Livefast123 Quote Link to comment Share on other sites More sharing options...
stu nesling Posted January 13, 2012 Report Share Posted January 13, 2012 be careful, i had to give up my hw35 springer as it was at 28ftlb without my knowledge :blink: Quote Link to comment Share on other sites More sharing options...
luvbus Posted January 13, 2012 Report Share Posted January 13, 2012 IIRC one of the features of the BSA Supersport being able to adjust the power using slotted washers behind the piston?? As said above make sure you get it checked out properly after messing with it. Quote Link to comment Share on other sites More sharing options...
the crowman Posted January 13, 2012 Report Share Posted January 13, 2012 (edited) When i was a lad they were all springers buy an ox spring put that in and cut about i think it was about 5 to 6 rings off the old spring what's in the rifle at the minute and put that in with the new one that worked for me Edited January 13, 2012 by the crowman Quote Link to comment Share on other sites More sharing options...
brett1985 Posted January 14, 2012 Report Share Posted January 14, 2012 the supersport was, and still is, a very capable gun when its working correctly. to be honest, they are as simple as you like. i would strip it, degrease EVERYTHING, get a new standard spring and seals, polish any metal to metal mating surfaces to NEAR mirror finish ( a complete mirror finish can stop the grease from sticking to the surface in some cases!) make sure you also polish the spring ends and spring guides (will help to smooth down the recoil slightly) degrease everything again when your finished, and then fit the new seals to the piston head and breach. add a very light smear of non combustable lube to the piston washer (i use abbey sm50) and put the piston assembly back in, being carefull not to damgage the piston washer. very light smear of cv moly grease to the spring and around the spring guide and then reassemble. if all is well, the gun should shoot smooth and be around the 11ftlbs mark. you will need to get it chrono'd though..... brett Quote Link to comment Share on other sites More sharing options...
Dekers Posted January 14, 2012 Report Share Posted January 14, 2012 (edited) As someone else mentioned, be wary of spending too much on an old rifle, costs can easily escalate here, perhaps a better option would be to look at something else!

The former needs to be modded to fire live rounds to get past 20 ft lbs :lol: !? Quote Link to comment Share on other sites More sharing options...
saggy61 Posted January 15, 2012 Report Share Posted January 15, 2012 +1 for the ox spring , I was forever going thrue standard springs on my supersport but since changing to a ox spring i havent had to touch it fo 10 years or so well exept changing the O ring on the barrel Quote Link to comment Share on other sites More sharing options...
NIGHT SEARCHER Posted June 5, 2013 Report Share Posted June 5, 2013 The best thing i would do is send it to sandwell field sports. For £65 you get a stage 1 tune the gun will be near full power and very smooth to shoot. You get a new spring. Polished cylinder. Polished piston. new top hat and spring guide. It will shoot like a different gun very smooth accurate and low recoil. By the time you have got a new spring and other bits you will be spending £40 to £50 and a load of grief.

kyska Posted June 7, 2013 Report Share Posted June 7, 2013 if over... The law makes no distinction between air rifles and more powerful guns for which you need a licence – they are all classed as firearms. This means that any offence you commit can carry a very heavy penalty – and there are at least 38 different offences. Courtesy of BASC.
