With unwanted "self-tightening" valve spring hopefully corrected, decided on another overall repair attempt. Completed full cleaning and lube, followed by removal of DonnyFL adapter and re-installation of baffles/air stripper. Regulator increased from 130b to 150 and HS adjusted fully in, out enough to just allow side-lever operation. Shotgun patterns and pellet clipping forced return to DonnyFL adapter and (pictured) empty can (STO-FALX) for noise control. Chronograph revealed JSB 33.95s were leaving muzzle @ 650FPS so lighter pellets needed. Out of (26 grain) Predator Polymags, (27.47grain) H&N Barracuda Hunters, JSB Hades (26.54 grain) and H&N FTT (20.06 grain), only Barracudas and Hades grouped. Further HS adjustments and testing showed Hades was best with HS one full turn out, from seated, Six shot group @ 50 yards (pictured) with median of 840 FPS and SD 6.5. More Hades on order, further testing ahead but promising results, WM 
JTS Another try with Airacuda MAX .25

Agreed, if further testing reveals consistency, I'll have no problem with humane hunting/pesting @ 40 FPE. WMNothing wrong with that from a sporting/hunting rig

I think that gun is one of the best bargain options out there. They are nice for the money.

I'm STILL amazed that Hades are the most accurate pellet out of my Royale 500. Started using them about 5 or 6 years ago & never looked back.

ChefSparrow,
Sorry, we don't see eye to eye on that, two years MAX ownership, still searching for accuracy/consistency. Wooden stocks cut wrong, shrouds shaped like bananas, self-tightening valve springs, just to name a few. Would not recommend MAX, only silver lining is PCP knowledge gained, been apart more times than can count. WM

Had a tin for couple years, no PCP would group, tried many times. Glad I had them, kind of saved the day. Ordered another tin from Pellet Shop, 27% off .25 Hades sale. WM

My 2 are great but I do not recommend them, Travis ghosted us on 3 of the 4 known defects and even permanently glued the thread protector on the max due to poor quality.

The empty can (STO-FALX) moderator has an exit cap of threaded 1/2 inch x 20 since .30 end cap clips. "Banana" shroud is flipped to least warped end and still clips a .30 opening! WM

On my MAX .22 purchased October/Novermber 2024 the shroud 1/2-20 adapter thread protector was permanently glued/attached.
I used 3D printed moderators on my MAX .22 without any issues.
This is the free to print moderator I used:
LDCs that screw directly into the Airacuda Standard shroud - Airguns & Guns Forum
LDCs that screw directly into the Airacuda Standard shroud, Air guns, Airgun Forum

I just bought this M22x1 to 1/2-20 adapter and it fits well: https://www.aliexpress.us/item/3256807772468394.html
It costs $15.99 + tax, free shipping.
I have used several moderators with this adapter with no issues.

Is that Travis from Jefferson state/JSAR? Not surprising. I would not buy anything from him or anything he has his hands in.

"Subscriber" from Gateway to Airguns is one of the main reasons I am still visiting the site.
I have many of the suppresors he designed, and made free for everyone to print.

UPDATE 12/17
Finished last of JSB Hades after airing up last evening. Accuracy consistent with slightly lower 830 FPS and higher SD of 9.5, thus keeping hope alive. WM

Update 12/20
Thanks to The Pellet Shop for quick, well-packaged delivery of JSB Hades. Noticed a full air charge caused MAX regulator to creep from 2200 to 2300psi, which Hades seemed to prefer. After 10 shots, Hades grouping opened up. Re-adjusting regulator from 150 to 165b happened to stop creep and provided consistent Hades grouping, HS remained one full turn out from fully seated. Chrono work ahead but formula seems promising. WM
