Others Paradigm repair

["That doesn't seem completely correct. It's a 32 tpi thread on the adjuster which equates to 0.0026" per hour which is about 50 psi. It's important to note that the spring stack is not linear in terms of force/deflection, it's more of a bell curve, so depending actual deflection the rate will vary. At some point I will post a a calibration in hours/psi. It can get you close; there are so many variables it is impossible to have a generic calibration that matches every regulator."]

This is really good to know. I measured the change to be .005" on my regulator which changed it 250psi and I extrapolated out the rest.The actual starting length was 2.170" (for 2000psi) and ending length was 2.175"(2250psi). I actually moved it back 2 "hours" to do that. I was figuring that it would be close to linear in that close range, but obviously not. I look forward to your information as I really don't like wasting time guessing. Thanks Tom!

edit: Unless, of course, I have a bad regulator guage! Tom, do my numbers look right for the length of the regualtor? Thanks for the help!

When I have adjusted my regs Ive found it very close to 50 psi per hour on all three of mine.

Yeah, I know I measured thrice, with excellent Starrett vernier calipers, and my regulator says what it says, so now this has me wondering about my guage. I only moved ccw two hours and my guage, which originally read 2000psi, has been reading 2250 ever since. I got a jump of 50fps with pellets from the change. Is that the normal bump in speed for the change from 2000psi to 2250psi? I don't know, but I hope somebody here can confirm. If not, it's replace the guage time.

I have noticed that my reservoir fill gauge is slightly off, I have an airtanks plus fill station as well as a wika gauge on my compressor and that fill station I use when filling my SCBA tanks. The Wika gauges all match the airtanks plus gauge, however my airtanks plus gauge will read 3500-3600 and my air resevoir gauge on my rifle will read 4000.


Having worked in the automation field with pneumatic actuators and various forms of testing equipment I can tell you that I expect no less really, those small gauges IMO are REFERENCE points really and are typically not as accurate as a full sized test gauge.

I was just looking at Tom's numbers again and am relieved that I at least measured accurately, .0026x2hours=.0052
I don't remember changing my hammer strike, so I guess it comes down to the difference in speed of a 100psi change to a 250psi change in pellet velocity, without hs adjustments. I won't be changing anything until the new plenums come out but I am really curious if anyone has already figured this out through experimenting.

I too am waiting for the plenums before I fiddle but that will be some good testing just to see how it works out.

Woogie_man, sorry, I didn't want to hijack your thread! Just realized it, caught up in my own thoughts. I'll end this here.

 

[Woogie_man]

No worries man, what you are talking about is usefull information.

I should be able to go get some shooting done this weekend. Though we are in deer season now as well, so trying to balance my shooting hobbies right now. Lol

I agree with your assessment. 2 hours was about 250 psi. 3 hours was around 375-400 psi on the reg.

 

[Dairyboy]

When I tuned my 15" 4hrs was about 300psi so 75psi per hour. I'll need to look at what my Mini was.

 

[ctshooter]

Tom did say they can vary a bit. With my Huma regs and tester with a digital gauge it’s also varied between them.

 

[Dairyboy]

Yeah I'm sure it can't be set in stone. Also curious is maybe the changes made? Say mine was lowering from 1900psi to 1600psi.

 

[Woogie_man]

That is awesome information!

I am thinking about taking my guns in Wednesday and do some shooting. Need to get something done with them.

 

[Pumacarl]

Thanks guys, I was worried, only mine, or my guage, was bad. Now that I see others are the same, or different still, I'm not so concerned about it, as long as it stays consistent.

I have only ever adjusted my rifles down so maybe that is why your results and my results have been similar , if I did make an adjustment up it was ever so slightly.

Was able to get out and get some testing done. Started with the 25.4gr pellets at 950 fps, and then went to some Zan slugs in the same grain. Was hitting the round target with a center flapper with ease. 50 yards was no question, 100 yards was just as easy, 200 was a little more of a test but still very doable.

The ability to adjust the regulator and fine tune is awesome! The added consistency that the new plenum extension adds was seen for sure. Was averaging 909fps with a spread of a few fps. Planning on running the Paradigm in the next NRL22 match.


Looking at the rifle and the private range. 50 yard berm with the scope check plate from Atlas target works.



KYL rack at 40 yards, gong with center flapper at 100 yards ( center flapper is size of golf ball ), and the 200 yard plate.



View through the Tract Torric scope looking at the 100 yard target. With pellets it was EXTREMELY easy to smack the center of this target. With slugs it was just as easy, but slugs are far more expensive.

So you're saying your .22 is shooting slugs very well? that is fantastic news. Good shooting man. I'd love to see ya get 3 / 2 inch spinners out there and smack em. You're nrl22 ready now bud.

 

[Woogie_man]

Yeah the slugs were great. Was talking with Tom and he made mention that slugs up to 30gr are great.

I have some gongs those sizes and thought I brought them with, though in my rush I left them at home.

 

[Dairyboy]

Wow that's impressive! Would be fun to have one shooting heavy slugs like that!

This has been a great thread to read I must say. Mostly because you all are having too much fun. Following
