I asked CHAT GPT THIS….

[PasadenaMike]

I asked
“List me PCPs from most reliable to least reliable “ (I didn’t make the list the Lizard People did)





PCP Airguns Ranked: Most to Least Reliable (Based on Leak Resistance & Simplicity)

Compiled from personal experience, community feedback, and common failure points.

Most Reliable (Low Maintenance / Rare Leaks)

1. AirForce Airguns (Talon SS, Condor, Escape) – No regulator, direct valve, steel tank = rock solid.
2.Benjamin Discovery / Maximus – Simple, unregulated, 2000 PSI system. Great for long-term reliability.
3.Crosman 2240 PCP Builds – Basic and dependable when sealed right.
4.RAW HM1000X / TM1000 – Built like tanks. Regulated, but high-end machining = minimal issues.





Moderate Reliability (Good but Needs Attention)


5. FX Impact / Crown / Maverick – Excellent performance, but complex systems mean more seals and potential leak points.


6. Daystate (Huntsman, Red Wolf) – High quality, but electronic systems (especially Red Wolf) can be tricky when issues arise.


7. Weihrauch HW100 – Great guns, but not user-friendly to service if leaks start.

Least Reliable (Frequent Leak Complaints)


8. Hatsan PCPs (AT44, Flash, BullBoss, etc.) – Inconsistent QC, common valve and fill port leaks.


9. Umarex Gauntlet (especially Gen 1) – Regulator creep and slow leaks are common.


10. SPA / Artemis (P15, M16, etc.) – Budget builds, but sealing issues are well known.




Dishonorable Mentions:

• FX Monsoon – Legendary for how unreliable it was.
• Evanix Semi-Autos – Cool on paper, nightmares in reality (leaks, jams, electrical gremlins).

Feel free to add your experience—especially if you’ve had good luck with one that’s lower on the list. Just trying to help fellow shooters avoid the “leak-chasing hobby.”

as for me all I can say AAA EVOL!

 

[Pumacarl]

Well I haven't run a million simulations a second lately, like CHAT-GPT, but I have put over 25K pellets through my Gen 1 Gauntlet, from the very first production run, and it has never leaked, or had the regulator creep either. The Daystate Huntsman didn't deserve to not be in the top list either.

 

[PapaT]

Interesting results, I won't argue with it, as I haven't the breadth of experience to void it. But... I've never had an issue with any Hatsan I've shot.

Yeah same here my Hatsans just worked

How many rounds down range with any PCP has chatgtp sent? Answer zero… Value of its very own opinion in the matter? Zero. It cannot put hands on and appreciate any PCP. Simply collected data…

No but it’s fun asking it’s like the modern day one of these

Magic 8-Ball & CHAT GPT, sounds about right! lol

After seeing this thread I had to ask some questions:

Calculate the twist rate for Nielsen Specialty Ammo .249 | 26.8 gr | slugs traveling 850 fps from an air gun using the Greenhill formula

Spoiler

To calculate the twist rate for Nielsen Specialty Ammo .249 | 26.8 gr slugs traveling at 850 fps using the Greenhill formula, you will need the bullet's diameter (D) and length (L)
.
The Greenhill formula is expressed as: T = (C x D^2) / L

Where:

• T is the twist rate (in inches per turn).
• C is a constant, usually 150 for velocities below 2800 fps. Since the slugs are traveling at 850 fps, C = 150 is used.
• D is the bullet diameter (in inches). In this case, D = 0.249 inches.
• L is the bullet length (in inches). According to NSA specifications, the length of these slugs is 0.290 inches.

Calculations:

1. Calculate D^2: 0.249 inches * 0.249 inches = 0.062001 square inches.
2. Calculate C x D^2: 150 * 0.062001 square inches = 9.30015.
3. Calculate T: 9.30015 / 0.290 inches = 32.069 inches.

Therefore, according to the Greenhill formula, the calculated twist rate needed to stabilize these slugs at 850 fps is approximately 1 turn in 32.07 inches.

Important Notes:

• The Greenhill formula provides a general guideline and is a simplification.
• Other factors can influence the optimal twist rate, such as bullet shape, weight, specific gravity, and atmospheric conditions.
• While Greenhill's formula is useful, it has limitations, particularly for modern, high-velocity projectiles.
• The cited source notes that the length of the .249 caliber, 26.8-grain NSA slugs is 0.290 inches.
• A user on a forum thread noted that for NSA 26.8 gr slugs, a 1:24 twist rate stabilized them, but a 1:18 twist provided better accuracy at longer distances. This suggests that a tighter twist than the Greenhill formula calculates might be preferred in some cases.

Not to get off subject but it’s an absolutely useful tool for business and every day life

Amazing!!

Oh, and I want to add something, from my real everyday life: the only gun, not just airgun, but the only gun in my life, that I ever pulled the trigger on, and it didn't fire, on not one, but two occasions, was my Airforce TalonP.

Like a locked trigger?

 

[Pumacarl]

Like a locked trigger?

The safety wasn't on, otherwise it would have been right, it just refused to fire. I had to push the bolt all the way forward, hold it there, and smack the gun, then it worked. The trigger has never been worked on either. I honestly don't remember if this was before or after I removed the toggle, but if it happens again, I will tell you about it for sure. I love simple and reliable too, but I don't like crude, and this trigger group is that. I like the gun, but I won't sugarcoat it. I will be painting it this weekend though.

Number 10 the Artemis M16B 25 caliber is one of my most reliable and accurate air rifles. I've been shooting it for about 2 years with no problems. I guess i just got lucky with it i guess! The ones that give me problems are the Air Venturi Avengers and Avenge-X. They leak all the time, always need filling when i put them back in the safe full of air i take them out and they have went down 2000 psi. Number 9 the Umarex gauntlet 1 and 2 series the 25 and 30 cal have been super reliable for over 3 years. Brocock, BSA, all good!

 

[Danman]

Ahh is this the Same Chat GTP that thinks shells fly with bullets when fired?
Heeeey Where's AirArms and Brk on this list!? Near the top no doubt I asked it the same question but for Springers. AirArms didn't make the list again.... It's rigged I say!

lol the shells and bullets are the best lol.

If my Talon P or Condor SS ever act up they’re fired .

Not me, I'll fix'em, they are solid little buggers! I really wish someone would figure out a good way to upgrade those trigger components though.

Mine are a bit weird but man they put ground squirrels down. The safety is always a song and dance
