I´m in love with my WST again !
I´ve been fixing and tinkering with my Cricket WST .25 lately, more than shooting it. Imppu & Hannu from Websales in Finland (my trusted Cricket dealer and also the Finnish KalibrGun importer) adjusted and send me an extra regulator, which was set at 130 bar and market 110 b – 150 b in 10 bar increments to ease the future adjustements. I also adjusted the valve 3/4 turn in from “the touch down” as per Ernest. I changed every single OEM Russian o-ring to better quality stuff (Ernest Express) and Imppu also send me one of his newest HST adjusters (shorter threaded plastic part and much longer spring guide) and that also went in with Dr. Evil´s Delrin HS sleeves. I´ve polished and smoothed out the whole trigger assy and all the parts inside the hammer housing. I also changed springs on the trigger rod untill i found the one i liked best.
Now i have a cocking action that´s buttery smooth and the trigger is Match-issue. Not close,not near but bona fide Match ! :4:
Everything buttoned up i filled the gun and put my rusty , but trusty ,Combro on – with some new parts after the little mishap we had with it and that damned .308 cal Howlitzer – and went for it at my backyard range (+- 35 yards) to check the velocity. Fired the first shot and there was no need to even check the Combro reading to know it was shooting HOT. The backstop is a 1,5″ thick wooden thingie and the pellet blew straight thru it ! 😯 😯 I checked the reading and it said 304 mps. Turned the HST adjuster out untill i got it down to 280 mps where i wanted to be.
Anyway – the next thing i wanted to check was the consistency in velocity so once down at the more humane level at 280 mps, i shot two mags , 24 shots , to check the deviation. Well – the slowest shot was 279.7 mps and the fastes one was 280.4 mps. 14 of the shots was exactly 280.0 mps. With my world class math skills i got the extreme spread to 0.7 mps (or a hair shy from 2.5 fps for you with that stone age Imperial system) for those 24 shots.
Those 24 pellets (plus one dry shot = 25 shots) used 40 Bar so there is room for improvement but i´m very satisfied with my progress thus far.
All this tells me that the next step is to try the reg at 120 Bar but before i dive into things again i´ll just shoot the thing for a while to find the best velocity for those 25.4 gr JSB´s/FX´s and i´ll also test the H&N Baracuda 31 grainers to see how those behave in my Bug.
Time to get into Airgunning after the Powderburner hiatus again , or so it feels like right now. It sure is FUN !! :4: :4:

We have these (Combro on Steroids) 😛 Much more expensive but they seem to work really well.
I know a few guys using the CEDs. They say go with the IR. My local range bought three Oehlers for official results.
Much better !
I have my eye on one of these :

I guess it does fit Hoot’s chicken. 
If I was manufacturing guns in a small shop and wanted something quick and dirty it would be perfect. 😀
There is one (1) good thing about that little plastic device though : You always get the reading from the same exact spot.
Oehler $575 – built in printer that works correctly.
How dare you badmouth my Combro ?? 😯

The only thing worse than a Chrony is a Combro. 😆 😆 😆 Best thing is to shoot both of them and get something decent. 🙂
:1:
We´ll see but for now it shoots brilliantly !
I couldn´t believe it myself at first but the trusty (albeit a bit rusty) Combro never,ever lies to me. It´s not a Chrony … 😆 I´ll be at the range tomorrow, despite the weather, and will do more shooting and Combroing. The funny thing here is – either i was extremely lucky and got everything right with the first try OR that was just an odd thing with a new Regulator. What makes it even more weird is the fact the reg is spanking new and although adjusted with a manometer and all it has had no shots thru it and hasn´t have any time for break-in.

BTW – The centigrades are much more logical : Water boils at 100 degrees while the freezing point is zero degrees Celsius.
You´re right about the Third Reich though. The “der”,”die” & “das” is a conspiracy ! 😯
EDIT : The freezing point is -1 degrees. Zero is …. zero.
Ville, the ES is hard to believe! Out of the box, my .25 outperforms the Edgun by a little.
I know what you mean; freezing rain and 32 more-precise-than-centigrade-without-decimals degrees F.
By the way, the imperial system is our way of knowing if foreigners are in our midst. If a person can’t instinctively speak in these measurements, they might be a spy! It’s kind of like the “der, die, das” in German-if you’re not native, you’ll screw up sooner or later.
Before the tune-up i got around 4.5 mags (54-55 shots) before the POI started to drop. That at around 280-285 mps with 25.4 gr King´s (or FX). I haven´t much shot the gun, and even less with the newly adjusted reg /valve spring/HST but i will get back to Airgunning now again and do real strings and stuff so i´ll be able to give a better answer soon.
very nice group, Ville,,,
how many shots will you usually get per one fill …??
I´ll take pics soon. Just waiting for my newest CF shroud to arrive. It´s 60 mm shorter making the shroud end at the same place as the air tube does = looks wicked – or so i hope.
I need to shoot you some 50m groups although this time of the year the Souther Sweden is infested with hard,gusty winds and rain,rain,rain … Makes shooting small groups at outside a great challenge.
I assure you one thing : It beats both my EdGuns in accuracy. Let me refrase ; It makes them look like Gamo springers in comparison!
Just kidding with that last comment but it´s definitely every bit as accurate as any EdGun. My first time out with it – groups , without any adjustement to anything , at 50m and 12 shots (a mag) were around 12 mm C/C without even trying to concentrate for any grouping since the gun/barrel/everything was right out of the box. The .22LR casing is 15 mm long to give an perspective on things.
Every Bozo can muster a small group with 3-5 shots ( just ask Wingman,OG,Demp etc. Those guys can shoot smaller groups with 20 shots than most here do with five) , thus i did several 12 shot groups, just to break her in a bit.
Like said – shot with a brand new gun without any adjustement to anything so take it for what it is. I also managed to pull the second-to-last shot (naturally) a bit to ruin the otherwise O.K group …
Brother Ville;
i am happy too that you are happy with your Cricket, and your all mods that you have made ,,,, great ,,, but i would like to see the accuracy test within 50 mtr or more …
this is nice to get what you have paid for… or if the stuff deserves your spent money ,,,,
would like to see more and accurate details about your gun…

That one looks really good ! I like the way its sensors read the velocity : Always at the same exact point.
