what the hell could be wrong with it

[pedro68 3]

Hi there ,im hoping someone can offer me some suggestions of how to fix my Hw97k,firstly i put a v mach tuning kit in it and once it was ran in it was great,very consistent at about 11.6ft/lbs, i crono it regular on my combro crono , now its started to give really strange readings , its varying between 11.1 and 11.7 and all over the place :wallbash: , no 2 shots the same ,i stripped it down and checked everything ,cleaned and re-greased every thing and rebuilt it and now it slightly better but not where it used to be and not as consistent . can anyone tell me how there hw97k perform and are these readings im getting ok. what does everyone else get with there guns and what else can i do to get it steady . thanks in advance

Erm, don't you have to let it settle down, you know, put half a tin through and see what happens or is this happening after that?

[Buster321c 1,010]

11.6 is taking a risk IMO ......

[secretagentmole 1,701]

Buster is 11.3 ok on a pcp or is that a bit high in your opinion? Just the X2 is running at that on a 60 shot string!

hi there , it was settled , had thousands of pellets through it, but now its all over the place , im at a lose on what to try next

[pedro68 3]

i would be happy with 11.3 if i could get it there and it to be consistent

[secretagentmole 1,701]

Ah, I mis read it

Pianoman knows HWs inside and out, could try asking him!

Tried a different chrony.

 

Just a thought mate.

Mole 11.3 is fine .

 

 

Have you changed pellets recently ?

 

Cleaned out the barrel ?

[andyfr1968 772]

Try another chrono if you can. Those little Combro things aren't always the most reliable.

 

If your 97's had that many pellets through it, it should have settled long ago.

 

If the shots tend to be on the low side, have you checked the breach seal?

 

Cheers.

ive been using rws superdomes for a while as the gun likes them, on a test with ten pellets the readings are about 11.5 but an odd one will go to 11.8 which puts my average up, some are 11.3 . its a big diffrence between the highest and the lowest, this was never the case before . i was at my gun club at the weekend and cronoed my gun on the club crono and it was 11,5 ish but there was a high reading on one at 11.88 which is to high for comfort

[pedro68 3]

fitted a new breech seal tonight, made no diffrence , im i expecting to much from a springer all be it a bloody good one

[Buster321c 1,010]

I agree that 11.8 is too high , but i also think there is a tendency to get carried away with the chrony , and especially when its `consistency ` that your looking for . 11.3 - 11.8 , with an average of 11.5 , ive seen worse , much worse .

i know what your saying ,and after all the tinkering tonight it may settle more once i get a couple hundred pellets through it , as iv just got a my first couple of permission and im going to be out on others land i want it to be right and within the law , am i right in thinking that if its inconsistent my hold over etc at longer ranges will be effected,and for hunting purposes thats a worry

whats the fps difference rather than the ftlbs,i wouldn't think it would be too much to worry about.the variation could be caused by too much grease on internals giving inconsistent readings.just a thought,good luck anyway mate.
