Technical Analysis of the HW100
hw100 fac
Hi guys, I'm from holland, and have a hw100 fac 5,5 . 265m/sec. on chrony, with a H&N FTT weight, 0,97 gram. was about 33 joules.
I agree that the air cilinder is to small for the 35 joule type, only doing 45 shots with it. And Yes, here in holland there is no limit in velocity....
Does anyone knows if the regulator on my hw. is put to the max.?? and if I increase de presure on de hammer spring, will that make a change in velocety ? with a fac model???
thanks oane.

we passed 350m/s but, it is unusable with this cylinder, you have to attach directly on scuba usable shot count is decreased to 10-14 shots with cylinder and the silencer must be unf type , mine is attached with a little grubscrew and flied off and when you pass the speed of sound you cannot silence it anyway... But this level is destructive for belleville washers, and if you dryshot accidentally (with no air inside the tube) you can definately damage the valve unit irreversibly.
After trying different power levels, Passing 25 ft/lbs is innacurate for .22 HW100, because of it's loose barrel. i use 5.52 mm FX pellets for accuracy. i can say the rifle is very good at 20 lb/ft power level, it shoots about 750 ft/sec and +- 4 fps deviation. it groups 7mm at 50 yards. My washer configuration is

Hope it helps.

Hi all
Brilliantly interesting thread, well done and thanks to all that have contributed ETA, sniper e.t.c.............
Although I have read the thread several times as you can see from my post count I'm new to the pcp world but have recently bought a 3 year old HW100s .177 and would like to uprate the power a little.
I just want to make sure of the details, idiot proof them if you like.
I have a chronograph and the tools and have had the gun apart and back together to service it but like I say I just want to make sure of the details before I turn any screws, the gun currently shows 11.74 lb/ft on the chronograph.
I'd like to uprate the power to about 18 -20lb/ft.
I understand that the hammer spring and the regulator need adjusting and you can also adjust the arrangement of the disk springs. Problem is that because I'm a bit thick when people then start talking about velocity dropping off despite the increase in lb/ft everything I thought I understood turns to confusion.
I would be very grateful if someone could explain in easy steps/layman's terms what I need to adjust to reach the extra lb/ft I'm after
thank you in advance

I'll think you have the 16.3 J with the 41cm barrel, I have also this configuration.
You can also play with the washers of the regulaor, mine is set in this congfig. ))(())(())(())((
The max. speed, with the hamer not to high, with Jsb exact is (+-) 275 m/s, this gives 20,4 J
When you have the 60cm barrel, this will increase to 290 m/s (22,7J)

You can easily achieve that power with just setting up the regulator and hammer spring correctly.
You can get an insight to the adjustments necessary from this PDF (use Google Translate to translate the text)

thanks gtir500 !
this is a fantastic guide on tuning the HW100 !! This one should be translated in English once for the users that do not speak Spanish. But, there is one but, he does not state what the starting point is. When screws the rifle together again, he gets around 20 J without adjusting settings. That makes me think that he has the 16,x J version which possibly has the more rigid hammerspring already (that's the one I bought, the "exportfeder" from WaffenSchneider in Germany. But it also can be that this version has a different regulator piston already. The "different" regulator piston I found, was the one that is used for the FAC (>30J) version, also on WaffenSchneider. So to stay in the 20-25 J range, I only change out the hammerspring for the more rigid one and leave the original regulator piston in?
My starting point is the 7.5 J version as sold by WaffenSchneider.
Groeten,
Johan

Hello Johan,
I thought with that name, you must be a persone, with Duth roots, ghghgh
Do not forget, that a longer barel, will give you also a higher speed of the pellet,... on the same setting
The new HW100SK, F-version, have only a 31 cm long barrel, so you will never get the same speed, as the fac-version.
If I where you, I will give it a try without change the original regulator piston .
And please, tell use what the results are

I just came across this string and have been informed by TW Chambers www.gunspares.co.uk that they are getting in spare parts for this gun and have a few parts already listed in stock.

For me this guide is not done very well because we must know the pressure of working with a pre-gauge ...gtir500 wrote:Johan

That is verry hard to tell, you have only one solution, and that is measurre the speed, certain with your laws in Germany (F-version)diehard84 wrote:hi,
i have cleaned and oiled my hw100 and now i´m not sure about the original position for the "C3" Screw on the "F" Version (how deep).
If anyone can check it (please in mm) or know it please post it here
When you have a difference off a few 1/10 of a mm., there is also a difference in speed off your pellet.
Find with a friend a shooting chrony ore a combro, ...
ore go to your dealer.
