   js is proberly right about your rifle,but higher fpe isnt everything when comes to airgun hunting,i have no hesitation taking a 12fpe 177/22 cal gun small game hunting as js said they doso very effectivly in the UK out to considerable distances with 12fpe rifles i have 177cal pcp rifles that are twice 12fpe and 22 cal rifles up to 3 or more times 12fpe i use for hunting,the only real advantage more than 12fpe is the rifles can effectivly use much heavier pellets a decent velocitys,it really all comes down to accuracy accuracy is key for effective airgun hunting,any rifle that will keep 5 shots within 10mm at 15yds will be very capable of head shots on rabbits etc out past 50yds as many forum members can attest to,there is no point chasing more power if accuracy deterorates at higher power levels as it can do at times, there is bound to be a 16gr pellet this rifle will shoot very accuratly,its just a matter of trying different 16gr pellets til  you find one that will give you the accuracy you want thats my two bobs worth anyway.
 cheers mike

	Thanks J-S tried the 16g JSBs but the accuracy wasn't there, the 14g JSBs shot real well. Will put up with the tang, next time I'll go the TBT way.

	The HW80 should be around 20fpe. it may be a case that its in fact a UK sub12 model? if that is the case, it may be oversprung which is trying to force power resulting in a harsh cycle. Its a large capacity rifle so at 18fpe it should be pretty smooth - like a 17/18fpe rifle performing at 15fpe will be a lot more tame. sub12 will usually have "Hull Cartridge" on barrel. OX mainsprings are notoriously reviewed as pretty average and removed pretty quickly by airgun tuners.. id stay clear. Weihrauch original springs are likely some of the best quality around. I would try and ascertain for sure its not a 12fpe model, then give it a strip down, clean out, re-lube, change the seal and spring to HW original, (also look into Titan springs for aftermarket) Polishing the spring ends and using a little moly paste can help twang Or go the tuning route - TBT (airrifletuning.co.uk) have a pro kit including spring guides and spring etc http://www.airrifletuning.com/store/weihrauch-hw80-35-maxi-tuning-kit/ Nick from TBT is helpful, so he may be able to give advice as well - to ascertain if its a full power or UK version. Weihrauchs do twang, the spring guides are steel and not usually a tight fit (perhaps allowing some variance in spring winding?) so can be a little harsh until they settle. Tight fitting guides will eliminate a lot of the twang and a thin layer of grease will help as well. Id use a dry spring in a low power target rifle but not in a high power sporter.

	To get rid of twang, you can fit a kit that has guides for the spring. Tin Bum tuning sell them. If you take the gun apart and can measure accurately the spring ID and the ID of the piston, it's pretty easy to make up a top hat spring guide for inside the piston. Then using some coke can, or coke bottle make a sleeve for the spring. These take up the gaps around the spring and absorb vibration that causes the twang.

	Has a inside spring guide. Doesn't have the outer spring sleeve like the Vortec kits have, can see how that would stop the twanging.

	Need Mike to comment, he is an ace at problem solving. Did it have the spring guides? I forgot to put them back in on a gun after a rebuild and it's sounded like a church bell after each shot.... Another option to try is put a washer in behind the spring to give it more tension/pressure (some people call the power washer etc...)

	Have you tried a heavier pellet in it? you might find it likes the extra weight when firing.

	From what I understand it does. I've greased the spring on the gamo, just a light smear around spring. No lumps or clumps. piston as well. TX will get it soon as its just started that twang sound. As I haven't touched it since I brought it, I'm guessing it's due.
