I bought a second hand Weirauch HW100K with thumbhole stock in .22 Nikko Sterling Gameking Side LRX 4-16X50 AO IR All the above is two years old and in excellent condition. I have noticed two things while setting up the scope 1, I only get about 50 shots befoe the gauge drops to about 90bar from 200 and the pressue drops overnight by as much as 80bar!!! 2, I noticed that the silencer was loose so I tightened with my hand and the barell started to rotate with ease, I can just keep turning the barell in either direction, should this be possible? Has anyone any ideas on how to remedy the problems?

You'll need to have that replaced. I don't believe the barrel should be able to turn. I'll ask my buddy what the problem could be since he's more at home in Weihrauch rifles, and he owns a HW100SK. I'll get back to you about it as soon as I get an answer. _________________ BIG GAP   Posted: Wed Mar 31, 2010 4:34 am rikwalter New Member Joined: 30 Mar 2010 Posts: 9 Location: Dorking, UK Hi Broommaster2000, Many thanx for the reply.

You should be able to find it with a parts diagram Provided by my local airgun-buddy, Jan. _________________ BIG GAP   Posted: Wed Mar 31, 2010 1:28 pm rikwalter New Member Joined: 30 Mar 2010 Posts: 9 Location: Dorking, UK Hey, Found the grub screw, it was loose, not by much but a quick full turn and all is in order. I have marked my barrel in case this happens again as I now have to re-zero, shots dropped a bit and to the right!! Many thanx All I need to do now is find out how to increase the power by a bit as it is apparently only shooting at 10.5ft/lbs, I would like it back upto 11.5ft/lbs but not over 12 as i don't have a FAC but do have a Shotgun Cert that I do not want to loose.... _________________ Cheers RiK HW100K TH .22 NS Gameking 4-16X50 AO IR LRX White Diamond O/U 30" MC Sporter Don't come round my house dressed as a Pigeon Weirauch HW100K TH - Barrel moving     Air Gun Home Forum Index » General Air Gun Questions and Topics You cannot post new topics in this forum You cannot reply to topics in this forum You cannot edit your posts in this forum You cannot delete your posts in this forum You cannot vote in polls in this forum All times are GMT - 5 Hours   Page 1 of 1   All Posts1 Day7 Days2 Weeks1 Month3 Months6 Months1 Year Oldest FirstNewest First  Select a forum Main Forums----------------AirGunHome Q&AGeneral Air Gun Questions and TopicsPicture GalleryTarget Shooting: Casual, Fun and CompetitionHunting, Pest Control, Varminting People/Events/Airgun Issue Discussion----------------Introduce YourselfThe BS TopicClubs/Events/Regional/Political Airgun Issues Maintenance, Modification and Reviews----------------RiflesPistolsAntique, Collector and Novelty AirgunsBB GunsPellets/AmmoOpticsAccessoriesAirgun Smithing Buy, Sell or Trade Forums----------------For SaleWant to Buy   Note: If you are seeing "Please enter your username and password to log in."
