This is a pressure gauge that just reads the pressure?, not a regulator or valve set up?

Looking at gauges, there are some with M10 thread. I could probably quite easily fit one on the front end of the cylinder, so I will get one to try for this.

I remember you saying you fitted that huma reg into her.
Before Elly, in another time and another place, I had a S410 for many years which was also not regulated, but shot beautifully. So much so that I never once noticed a power curve in that rifle. Would just fill it up to 200bar and shoot it... Super accurate every time.

Weihrauch also have some sort of clever valve system in the HW100, which I believe technically cant be called a regulator, but effectively does the same job? Anyone know anything about it?

Pete, your Elly wasn't originally regulated. AA have a very good valve system.

I know I rember thinking when I was playing with one, that there must be a optimal pressure where you get rid of the first part of the curve. After all it loses pressure with those first shots to get to that flat spot.

That shouldn't be too hard. The big thing is that as I am really amatuerish at it, what I make is quite bulky, and to keep a pistol a reasonable size, but still put in a reg, it will compromise tank size.

Also regs, gauges and mags easily add $200 + to the build.

Regs aren't alwaks needed if you can get a good valve hammer ballance.

With that build of mine, it did have a good amount of very usable shots if you look at the shot string. I actually think that getting the triggers better go a hell of a long way to making it accurate.

Just re read through this thread...
I'm very keen to see how your current .25 cal build compares to these two previous ones, the progression as you are figuring out better designs and techniques.
If you can figure out a way to get a regulator, a mag and a manometer in there I think they would be awesome!

It was just a piece of wood. Those two shots were actually the first 2 after a fill. If you remember, the speed can be a bit low after a fill until the pressure drops, then the hammer has enough energy to open the valve completely.

Or they have hit old pellets already embedded in that bit of wood, as i've used it before to put targets on.

If you look back through this thread I have groups at 15m that are shot with 18 grn. I have tried rws and 15 grn JSB and the 18 grn JSB seem the best and yeild the best power from the pistol. I don't sort my pellets, but check the skirts as I take them from the tin.

Pretty sure those groups can be tightened with a better shooting position.

Couple more questions Pauly.
Whats behind the 20m target? I've noticed a couple of pellets haven't gone through paper.
Were you using strait out tin pellets as one of the ones that didn't go through has a lot of skirt damage that doesn't seem to correlate with how it sits in target.
Have you tested for best pellet or these just ones you were using as you had them.

Plenty on Web about DIY cheek raisers. Was looking into it couple days back for sig, which I don't get a cheek wield on either. Few good ideas on the nz hunting and shooting forum that popped up when doing a DIY search on the subject.
