Hw99S Out The Box Vs Home Tune Review

[tomburras 2,729]

Great - Bet your well chuffed. Looking forwards to the updates!

So I have put her back together tonight...when I say put her back together, she 98% complete, only noticed a shim had slipped out when screwing the barrel pin back in place.lol and the fecking little bolt that goes in the trigger has been a pain in the arse so will have to sort that out tomorrow now. I checked to see if she cocks and locks into place and took a few test shots and things seem ok. Just need to put that shim back in place and get the trigger guard screwed into place properly.

 

I didn't put any power washer in, didn't bother with the metal piston sleeve either. I'll chrono her tomorrow and see roughly what she's putting out ft/lb wise and I'll know to add washers when I shim and bolt back in place.

 

These are a pain in the arse to work on in comparison to my HW77, or should I say this ones a pain in the arse. The bolt that locks the barrel in place must take ages to screw in. Crack on again tomorrow and finish the re build grrrrrrr. Haha

I have been able to fire some shots over the chrono, I realise the spring needs some pellets putting through before it beds in, but ATM I'm getting between 735 - 745 FPS what's about 10:30ft/lb. question is when I take it apart tonight to add the bits that's need adding. Do I put a power washer in or leave it as it is bearing in mind it's a .177 and could become jumpy??

I doubt you will find much difference with power washers mate, they seem to make bugger all difference in a 99, but do report back, your findings may be different, I take it you went with the standard seal and did not buy a Vortek?

ATM Ive stuck with the standard seal but in due course I'll be looking at replacing that as well as a barrel cut and thread.

Thought I would do a 10 shot string over the chrono and show what power she's putting out consistanly.

 

#1 738FPS 10.16ft/lb

#2 740FPS 10.21ft/lb

#3 736FPS 10.11ft/lb

#4 742FPS 10.29ft/lb

#5 735FPS 10.09ft/lb

#6 744FPS 10.32ft/lb

#7 745FPS 10.34ft/lb

#8 738FPS 10.16ft/lb

#9 738FPS 10.16ft/lb

#10 739FPS 10.19ft/lb

 

So the lowest reading was 735FPS and the highest was745FPS so 10FPS max spread over 10 shots, so she's not shooting at max power but a level I'm more then happy with. Once the spring beds in I'm hoping she puts out a little bit more power but becomes slightly more consistent...maybe 5FPS spread.

Wanna know what that needs now?

Yes please mate

a washer. Just one. 10.9 all day long. Beds in at 11.1-2. Job done. Then you can sell it. To me.

[Rez 4,957]

Just v-mached me 98. To my surprise, after a tin, was way low at 9.8. I'm using hunters mind at 10.6gn. One washer, 10.5 with the hunters now.

 

Got a text from the pigeons just yesterday... "we've moved on"

Cheers mate, I plan to strip her at the weekend, I read about power problems in the .177 HW99 and adding washers caused them not to cock. While I have her in bits again I'll give it a try and post the results....10.8 - 11.2 was the range I was aiming for. When it comes to selling her you'll be my first pm

Ahhh I forget it's a 177. Don't worry

 

Great post Richie.

What that needs now is a correctly sized Vortek piston seal, adding washers will have little or no effect, adding a far more efficient piston seal, in my experience with 99s will, or a .22 barrel (much as I hate to say it)

I read up on the vortek piston seals and because I don't have a lathe I could have a problem re sizing it correctly, would that be correct?

[Richard Collett 102]

Silly question time...I'm having problems getting both shims in place when connecting barrel pivot point. one of them has a slight nick and it's stopping both fitting it. I no it works with just one shim in, if I grease the side without a shim on will that be enough over time or will I have to order a new shim?
