What calibre and what pellets are you using? Quote Link to comment Share on other sites More sharing options...
The Duncan Posted January 15, 2011 Report Share Posted January 15, 2011 I think the first thing to do is chrono a mags worth of shots and see what consistency you are getting. Q's Has it been used in an excessively dirty or dusty place? Have you put any oil in the wee hole below where the mag sits? Duncan Quote Link to comment Share on other sites More sharing options...
Albion Posted January 15, 2011 Report Share Posted January 15, 2011 When you say 'occasionally' does that mean several shots in a row or the odd pellet now and then? Quote Link to comment Share on other sites More sharing options...
UKPoacher Posted January 15, 2011 Report Share Posted January 15, 2011 I'll bet it is the scope at fault. Chrono the rifle, check the barrel crowning with a Q-Tip and if they are OK swap the scope. Quote Link to comment Share on other sites More sharing options...
bruno22rf Posted January 15, 2011 Report Share Posted January 15, 2011 Take it back where you bought it-the fact that it is 18 months old is not a factor unless they can prove beyond doubt that you have misstreated the gun in some way.I would try and agree that if they find the gun full of dirt then you will be liable for the service cost-but the gun would have to be returned to Hull Cartridge for an independant diagnosis.Before you lose faith in the gun you need to remind yourself that this is the ultimate gun from one of the finest makers in history-most likely something simple.

The Duncan Posted January 15, 2011 Report Share Posted January 15, 2011 Could be something as simple as the barrel being a tiny bit loose - easily solved! Worse case scenario - valve fault. They cost a oner from hull cartridge when they do the work. I hope its something cheap and simple for you Quote Link to comment Share on other sites More sharing options...
lefty 100 Posted January 16, 2011 Author Report Share Posted January 16, 2011 sorry its a .22.have read through instuction again and have removed and drained the cylinder as supposed to do if being left unused for more than 4wks.i only have a stirup pump,have retested and full mag groups seem much better even pellet on pellet a couple of times at 30yds.I wonder if moisture may have crept in,even though pump has a filter and moisture trap.now im only refilling indoors before use.need to test more when i get time to make sure.but thks for all your advice.

Clubshot Posted January 16, 2011 Report Share Posted January 16, 2011 Lefty 100 No Location Check out local Air Gun Club - sure there will be other HW100's on Range/s Try different pellets - Does make one hell of a Difference BOB/R Quote Link to comment Share on other sites More sharing options...
plumber Posted January 16, 2011 Report Share Posted January 16, 2011 clean the barrell, every time my gun shots a little off i clean the barrell Quote Link to comment Share on other sites More sharing options...
Albion Posted January 16, 2011 Report Share Posted January 16, 2011 Consider buying a scuba tank. It might cost a bit but the air you'll get will be clean, dry, and so much less effort! Happy shooting Quote Link to comment Share on other sites More sharing options...
UKPoacher Posted January 16, 2011 Report Share Posted January 16, 2011 clean the barrell, every time my gun shots a little off i clean the barrell I don't clean my barrel and never have except when trying some Pax made pellets that supposedly don't work in anything other than clean barrels. They didn't work in my clean ones either. I've put thousands of RWS Superdomes through my old HW77s and never touched the barrels. Same with the HW100 and AA Fields and my Prosport and JSBs. No need to clean barrels when you use good lead pellets. Quote Link to comment Share on other sites More sharing options...

No need to clean barrels when you use good lead pellets. i wash lube and weigh all my pellets and still clean my barrell when signs ov accuracy starts to fade, accuracy returns once cleaned, justed stateing a possible cause and through my own personal experiance, it what wrks for me.

FalconFN Posted January 16, 2011 Report Share Posted January 16, 2011 I give my barrel a clean probably once a year then put 20-30 pellets through before taking it out, and you notice the difference in accuarcy. Take 10 shots at a target, clean barrel, re-lead with 25 pellets then take another 10 at a target and compare. You might be surprised.

Andy75 Posted January 17, 2011 Report Share Posted January 17, 2011 Last time my 100KT went off, it was down to me fiddling with the barrel band - the one around the air cylinder that mounts into the stock. Somewhere there is a manufacturer of a band that doesn't grip the barrel - when funds allow I will be getting one, as it's a pain. I have heard of people just removing the band and hack-sawing off the barrel support portion - depends how ghetto you want your rifle to look I guess! The band is in the picture, about halfway along the sun-shade of the scope. Quote Link to comment Share on other sites More sharing options...

I don't have any problems with accuracy and I never clean my barrels. No problems at all. I though it was only the Prometheus brigade who bothered chimney sweeping.

On the HW97K and 95K I used to own, as well as my HW100S I've had for the past 4 years, I've found that if accuracy takes a dip, cleaning the barrel using a pull through with cleaning patches (1 with gun oil impregnated, several dry until they come through clean) can help to restore accuracy, after a few shots to add a very thin layer of lead to the bore. On my HW100S, I tend to give the barrel a clean about every 500 shots so I don't suddenly find myself out in the field with a rifle that becomes inaccurate - heading it off at the pass, so to speak. :yp: Quote Link to comment Share on other sites More sharing options...
