pez91 Posted February 8, 2019 Report Share Posted February 8, 2019 Iv had my HW80 for the best part of 10 years now and like to think its in good shape, but this model has been around a long time and im aware people have been tinkering with it just as long. I've done a little myself but would appreciate any input. In the last 6 months or so I've replaced the piston and breach seal, made a greased shim for the piston and installed a welsh willy drop in kit with delrin tophat, spring guide and power washers. I've also drilled the piston in strategic places to reduce weight, I've buffed and polished the piston the spring and the transfer port and also had the barrel honed. I'll be honest she shoots like a dream, i never plan on buying another air rifle. Im aware that iv already gone to great lengths to improve this rifle but good can always get better so all knowledge of tuning tikering or fettling a HW80 will be greatly appreciated.

washerboy Posted February 8, 2019 Report Share Posted February 8, 2019 Not sure there's much more you can do to improve it if you have fitted a WW kit. Great guns, in fact I keep looking for an older one Quote Link to comment Share on other sites More sharing options...
Hamster Posted February 8, 2019 Report Share Posted February 8, 2019 If it's running close to 11.5 ft lbs with decent fps variation then what more can you do if as you say it shoots like a dream ! The only way you could improve such a rifle is to spend money on fancy wood and maybe an old school Theoben long silencer. Quote Link to comment Share on other sites More sharing options...
Mr.C Posted February 8, 2019 Report Share Posted February 8, 2019 (edited) I don't shoot springer myself but there are a few 22mm piston kits being used for HFT but as far as I can make out they're not fit and forget. Think I'd leave it as it is. 4 minutes ago, Mr.C said: You tickle the trigger up a bit if you haven't touched it yet Edited February 8, 2019 by Mr.C Quote Link to comment Share on other sites More sharing options...
Ultrastu Posted February 8, 2019 Report Share Posted February 8, 2019 As above i'd leave it alone and buy another springer to tinker with . Why not something challenging like a bsa lightening or a smk Quote Link to comment Share on other sites More sharing options...
pez91 Posted February 8, 2019 Author Report Share Posted February 8, 2019 Yeah i thought i may of gone as far as i can but tinkering with my springer has become a way of life haha think im guna buy a silencer now though!. Might buy a cheap hatsan and see what i can do with that aswell. How do i get the ft lbs checked?? I know it was putting out 10.5 when i bought it. It shoots threw the side of an oil drum now so who knows. Quote Link to comment Share on other sites More sharing options...
Ultrastu Posted February 8, 2019 Report Share Posted February 8, 2019 You have totally retuned your springer and havent got or checked it over a chrono. Tell me thats a bad joke 😨 Quote Link to comment Share on other sites More sharing options...
pez91 Posted February 8, 2019 Author Report Share Posted February 8, 2019 Haha ok its a bad joke. (looks up price of chrono hurridely on amazon). Quote Link to comment Share on other sites More sharing options...
Ultrastu Posted February 8, 2019 Report Share Posted February 8, 2019 take the stock and scope off it and seperate it into different rooms .Then get a chrono bought as fast as poss.and check it . Hw80 s were designed to put out 20 fpe of energy.the hard part is keeping them under 12 fpe..most completely untouched 80s end up around 13 -14 fpe just by shooting them . Combro is what you need .they are about 50 quid. Quote Link to comment Share on other sites More sharing options...

I didnt think springers were big hitters, tbh i might jst take a coil or 2 off the spring if it dosnt sounds vastly over powered?? My grandad taught me how to tune a springer as a kid, i never assumed it to be a problem haha but then again he had an fac. Quote Link to comment Share on other sites More sharing options...
Mr.C Posted February 8, 2019 Report Share Posted February 8, 2019 Buy a cheap remmigton express in.22 and let me know how you get on. In fact if you want a cheap express, coincidentally, I can sell you one. Quote Link to comment Share on other sites More sharing options...
Ultrastu Posted February 8, 2019 Report Share Posted February 8, 2019 Problem is often the smoother and nicer a gun is to shoot .the more powerful it can be . Due to everything working in harmony and being the most effiecient Noise and recoil ..will tell you nothing of the guns energy Shooting at paper or tin cans will reveal zero .and that gut feeling about its power is you just needing a poo. . Buy a combro. £50 isnt a lot of money to keep you the right side of the law and out of hot water. Quote Link to comment Share on other sites More sharing options...
pez91 Posted February 8, 2019 Author Report Share Posted February 8, 2019 Taking it to gun shop monday. Says if its vastly overpowered he'l sort it or buy it if i want. He said if its only slightly over with the first pellet he fires he'l leave it because springers go stiff when sat for a few days then lose about 10% power after bieng used 2 or 3 times.

PPP Posted February 8, 2019 Report Share Posted February 8, 2019 If the gun shop gives you the gun back having identified it’s over limit you’ll both be in the Pooh, deliberate possession of an unlicensed firearm (deliberate as you enhanced performance) could result in an accidental holiday Quote Link to comment Share on other sites More sharing options...

The amount of legislation surrounding air rifles confuses me, iv got a barnett predator that will send a 400 grain bold at 430+ fps and its my springer thats the problem....what a country!!

PPP Posted February 8, 2019 Report Share Posted February 8, 2019 Why, and what was he doing with it? No limit on barrel or stock length on sub 12 air rifle, sounds seriously dodge Quote Link to comment Share on other sites More sharing options...
GingerCat Posted February 8, 2019 Report Share Posted February 8, 2019 There's nothing confusing about it, if it's over 12ftlbs you need a licence and he can't, by law, give it back to you. Invest in a chrono as already suggested for future tinkering. Quote Link to comment Share on other sites More sharing options...

PPP Posted February 8, 2019 Report Share Posted February 8, 2019 No what I mean I’d, if it’s sub 12 then you can reduce it, it sounds dodgy that he had it confiscated, must have been up to something Quote Link to comment Share on other sites More sharing options...

Ultrastu Posted February 8, 2019 Report Share Posted February 8, 2019 An air rifle becomes too short when its less than 600 mm or 24 inches in old money . Nothing to do with the barrel length unless its an fac ..for which 300 mm is min length. Quote Link to comment Share on other sites More sharing options...

Im sure thats the case regarding rifles which are 2 handed weapons, but the modifications he made caused the police to deem it a 1 handed break barrel air pistol. Which are limited to 6ftlbs, the rifle would not of been below that so i assume was classed as a section 5 prohibited weapon. It ultimatley lead to the guns confiscation with no further action.
