Regulated .177 at 1400 psi

I agree regulators should be tested before they are sent out. That is why I test my regs before I send them out.

You are getting that much variation because the output from the regulator is varying (but you already figured that out).
I am not familiar with the BSA and such regs. I have yet to tear into one and take a peak. I would not be surprised if they were similar to those being offered for sale just better quality.

I am considering putting a better reg on the market just busy with other project for the time being. At lower pressures I am happy with the results my regulators offer. Even thought there is always room for improvement.

I’d like to weigh in on this one. Oh and I am Mat Bean experthpa.com is my website and the above contact info is all correct.

What is definitely true with all these regulators is that they have the same design, similar internal pieces and even similar origin.

Someday I will get round to posting pictures on my website of the internals of 5 or 6 different brand regulators. They are pretty much identical. Differing in quality and cleanliness is what gets you the variation.

One thing I am hoping to someday impress upon the airgun community is that although a really consistent high quality high pressure regulator exists it hasn’t made its way to airguns yet. These are all still being lost in aerospace applications where people can afford a 150$+ regulator.

The regulators being supplied to the airgun community right now are giving you all mixed results because of one main issue: QUALITY CONTROL. Truthfully ANS (the brand I sell) is not alot better than some of the other brands being supplied. None the less the guy setting and selling you the reg needs to know what he is doing and should give proper customer support after the sale. If something isn’t working he should have you send it in fix it and send it back.

Washers binding, bleed up and other irregularities are in part going to be the nature of the beast given the quality of regulator that is currently standard. Only with truly expensive regulators could we deliver much better consistency. As it now stands the stuff we are selling you is all about the same. That is why we all have individuals singing out praises and some that have been disappointed.

Speaking for myself I can say that I am happy to make it right. I have gotten much better at understanding these things since I sold the first one. I am pretty sure it hasn’t been hard to get my attention when people do have problems and I feel I have improved the product through a better understanding and application of setting the regulators responsibly so as to get more consistent output.

Bleed up comes from when the spring pack slowly compresses under pressure over time. Irregularities basically come from irregularities in the materials used to put a regulator together. A difference of .0001 in the spacing of the washers in your spring pack can change the output of the regulator. That is really small. Think of it. You could get that kind of a difference in size by squishing all the grease to one side of the reg. The variation you see from one shot to the next not only has to do with super tiny variations in the regulator but all the other variables in your gun and pellets etc.

Thus unless we all get serious and start spending ridiculous money on very precise parts for these regulators you are not likely to get a total absence of problems like this. This is also a sign that the regulators are of limited quality and capability. And if the current suppliers are being totally honest with the community they will tell you that they can’t deliver a regulator that is never going to need maintenance or be affected by the limited quality of their product. Either that or they are trying to sell you something.

Higher quality you will have to pay for. For now there are reasons I don’t provide regulators above 1400 psi. Safety is one . . . consistency is another. I

I have heard the regs airhog is buying are being set more carefully by his supplier. He looks to be getting some good results from those that are using his regs and that is great. Perhaps someday I will tap into a supplier of higher pressure regs set responsibly with higher quality internals. I know it would help you all out as providing quality at competive prices is really what I like about dealing with these tanks. For now I am happy with what I supply and the results it provides.

If you are unhappy with the results you are getting the guy supplying you with the stuff is the one to talk to.

Hmm, did you figure out your issue?

I have the same setup (JDS air with the 2000 psi regulator) but it’s only deviating by + or – 20 fps. I’m using HPA. Factory hammer. I was using 15 gr. Gamo pells.

Setting on 12,5 was was getting 810 and 790. I was at my friend’s place using his Chrony and we were shooting from 3 feet away from the photo cells. Lot’s more adjustabililty (velocity) than with the standard TSS valve.

The guage on the bottle was reading approx. 2400psi.

This was a TSS with the the factory 12″ barrel.

What JDS does is that he plays with the # of washers in the regulator until it yields expected results…according to John at JDS.

Forgot to mention this is with 22 cal 15 grain Gamos.

Not sure about that but, the variance in fps when the regulator or air valve screws up is huge….Sometimes as much as 200fps deviation….Doesn’t seem that turbulance could be that big of a factor but, then again, I don’t know enough about regulators….

Could be the sensing piston is sticky or the spring stack is binding/cocking over.
Loosen the setscrew once you have all the air out of it and take a look.
check for rub marks and binding as well as good lube on teh piston oring.
