relivingmyyouth Posted April 11, 2008 Report Share Posted April 11, 2008 (edited) Don't get me wrong. It feels great, looks great, and in fact i'm really glad I bit the pellet and bought it. I love it; and its lovely Weihrauch silencer; and its little frrts!! BUT ...... My pellet testing tells me it's well down on power Best figures are 10.9 ft/lbs from a Defiant 5.48 with the next best 10.3. The highest velocity being 602ft/sec from RWS Hobbys with the next best being 575. Only 8 of 32 pellet types came over 10ft/lbs I have sent an email to Webley but I don't expect much help from them... I know that, rightly, 'tuning' PCPs is a no go area but if anyone has any suggestions I will be very glad of them. I've never worked on a PCP but have done a few springers As I said, all suggestions gratefully recieved Edited April 11, 2008 by relivingmyyouth Quote Link to comment Share on other sites More sharing options...
kdubya Posted April 11, 2008 Report Share Posted April 11, 2008 The mechanism of this rifle has been factory set to ensure its power falls within the current U.K. 12 ft.lbs. maximum kinetic limit allowed without possessing a firearms certificate. The hammer adjustment screw is bonded to the hammer and any adjustments made will break the bond. Unless rebonded the hammer spring compression may vary which will cause inconsistent power. If the bond is broken, consult Webley & Scott. seems most raiders are sent out at 11.2 max with a heavy pellet not sure of the weight of your pellets but 10.9 aint far out it aint gonna come at 12lb!! cheers KW Quote Link to comment Share on other sites More sharing options...
chrispti Posted April 11, 2008 Report Share Posted April 11, 2008 I had the same figures with my s410, I also found that my peak power was at 150bar not 190 as aa recomend, power droped off at 90bar. s410s are eaisly adjusted though if you know how, I adjusted mine to 11.5ftlbs using aa field 16g pellets. I only did this so that the aim points on my hawke sr12 scope would be more accurate as they are designed for the trajectory of a .22 16g pellet @11.5 ftlbs. After I did this the aim points where bang on, however I didnt notice any change in the guns performance. Depending on weather conditions and you capability you will still bowl bunnies over at 50 yrds with a 10.5ftlb rifle. Quote Link to comment Share on other sites More sharing options...
Big_Sam Posted April 11, 2008 Report Share Posted April 11, 2008 I recommend you check the seal on the pellet probe, mine was perished and I lost over 1ft/lb power. Got a new seal from webley for free and back up to full power. Quote Link to comment Share on other sites More sharing options...

If you got arrested and the police confiscate your rifle and ammo, I quite sure they would test the equipment you where caught with?

relivingmyyouth Posted April 11, 2008 Author Report Share Posted April 11, 2008 Thanks all for your help so far. None of my guns, all sub 12ft/lbs like Magnums of any kind. However Bis Mags, Bis Pest Control, Weihrauch Mags all come in around 9.5 ft/lbs and 440-480 ft/sec. Logun Penetrators 9.7 and 525. AA field 10.18 and 529. By the way its .22 I'm going to run with Weihrauch F&T Specials which gave 10.08 and 549. Single hole @ 20m. I will run a power curve from 190 down to around 80 and see what happens. Did seem to have a sweet spot around 150-160 but only a 1 pellet type test run will tell. My family are going to hate me Watch this space....

The airgun is tested using three weights of pellets providing a data spread over a wide bandwidth. In use are Eley Wasp, H&N Diablo Spitz Kugeln and RWS Hobby. Also tested are any pellets found with the airgun at the time of its confiscation. In cases of borderline results, say 11.7fpe for rifles, further careful tests are carried out using individually weighed pellets. Any single reading with any of the pellets that is above the firearm limit makes the gun a section one firearm. Information is passed to the Crown Prosecution Service who decide whether it is in the public interest to prosecute Quote Link to comment Share on other sites More sharing options...

Big_Sam Posted April 12, 2008 Report Share Posted April 12, 2008 Out of interest, what pressure are you testing the velocity at? My raider is 10 ft/lb at 190BAR 12 ft/lb at 140BAR Quote Link to comment Share on other sites More sharing options...
relivingmyyouth Posted April 12, 2008 Author Report Share Posted April 12, 2008 in the interests of testng pellets accuratly i kept the pressure between 160 and 190. I am going to run a power curve from 190 down to 80 with one pellet type, plot the results and see what happens from there on. thankyou all. keep the info coming Quote Link to comment Share on other sites More sharing options...
