9 ft lb hw97k that kicks like mule.

[Stevie-L]

I have a hw97k in .177 that is only putting out 9.3 ft lbs and still kicks like its putting out 14 ft lbs.does anyone have any idea what the likely causes are for this.the spring is one piece and is straight and has polished ends.can I shiiiiiite get consistent groups with it.

How many coils in the spring? Could be a number of things. Mach 1m5

I would have to go back inside of it and count to tell you that mate I have never bothered to do that

I had a very tired .22 example with the opposite problem,it could be cocked with your little finger

Breech and or piston seal failure,or just oversprung?.

I've had it on the chrony and it's as consistent as can be.i thought I just could not shoot until I got my hands on my mates Springer and knocked out 5p size holes out to 40 yards with ease off the bench.then I realised my 97 is crap

You got there before me. Probably one of those three.

When you say oversprung do you mean over powered?also do you mean a loose fitting seal?

Sounds like a split seal , check both your breach seal ( youv loaded but the pellets almost jumped out getting sandwiched between barrel and breach seal splitting the seal ) the pelled jumped all the way out you havnt noticed and dry fired causing the piston seal to split against the cylinder head crown .. easily done with loose pellets .. may even have cracked the spring .replace all 3 and change your pellets . Sorry bud

That's the axis pin fitted.the comp tube no longer moves and it is now a little easier to shoot but is putting out 11.5 with h&n field targets and that's with a brand new piston seal in so power should go up some more,is that right?I will wait for it to bed in and remove a coil and see what's what's after that.
Thanks for the advice

Maybe an idea to put some RWS Hobbies and JSB Exacts (8.44 and 7.87) through it to make sure it's not over, Steve.

If too close or over the top, that'll give you the option of softening it down even more.

How does it feel now?

It has definitely improved but still a bit uncivilized.i mean its easy enough to keep everything inside 20-25mm out to 35 yards but I know me and the rifle can do much much better than that.theres a chance I've not yet found it's best match pellet wise either so that may help improve even more.i will let the new piston seal bed in and chrono once more then take it down to just under 11ft lbs and see where things are then.

Maybe it just doesn't suit you.

I had a .177 '97 that I really liked - I loved how it looked and shouldered but, I just couldn't get it to shoot right for me - I know it might sound silly but, I tried different innards, different stocks, different scopes - I just couldn't get to grips with it.

I once managed to hit a 3" bell at just under 60yrds with a standing shot (a complete fluke in front of people at my local club ) but, I could never manage a decent 10 shot group at 35yrds so, I moved it on.
....... The chap that bought it is more than happy with it it and, I gather is doing pretty well with it.

Airguns eh
