Are the Korean guns still relevant?

Sadly.. the evanix line that comes in all calibers, like the Ibex..I only see them aviable in big bores 35 cal n up in airgunpro shop.. would love to try it in .30 n .25

I don't see anyone in USA .. no USA vendors no gun.. well my bad .New England airguns has most of the evanix aviable..will give them a call..

DE is not a person, he is a concept. "DE"-tuning in this context means tuning the gun to reduced power in order to improve performance.

"Blasphemy!"
Guilty as charged! And being a power freak myself, I can well understand your offense at my DE-tuning one of the most awesome PCP maxi-blasters in airgun history.
I present the following evidence of my power-hunger, as quoted from the chapter titled Precharged Pneumatic Pistol POWER, from my book Custom, Classic, And Otherwise AWESOME AIR PISTOLS!
"We love our toys, you and I. Being men-folk, we're fascinated by Physics. Rather, gizmos relating to Physics like wheels, motors, projectiles and shooting implements. Good thing we're fascinated by such tools; because lacking such benign interests, we'd never get our minds out of the gutter! And mechanical gizmos being immensely more easily manipulated than females, no wonder we take such sanctuary in our 'stuff'. Of few things more fascinating than mechanical things (and, arguably, females) are powerful mechanical things! Which brings us to precharged pneumatic air pistols."
So, having confessed my blasphemy, AND proven my power addiction, you must be wondering what is the method to my madness... THIS TIME?
Because I can't abide airguns that lose velocity with every shot, as do virtually ALL PCP maxi-blasters including Sumatras, Careers, DukIl/Evanix, Quackenbush and many (most?) AEAs, I have a long history of DE-tuning those that I find otherwise excellent enough to invest many hours in taking to levels they'd never reach on their own. In the case of the Korean lever-actions, like this-
Four consecutive SIX-shot groups at 100 yards.
And this-
And in the case of AEA, this-
None of the feats documented above are possible with PCPs losing velocity with every shot; at least without recharging every couple/few shots, or tethering. So that's the method to my madness...
THIS TIME.

I'm not sure if this was said by AirNGasman or Desert Silver
My .25 Sumatra DE-tuned to 'just' 63 foot-pounds to return a 30 shot bell-curve power-band consistently averages 1.25-1.50" SIX-shot groups at 100 yards.
But now I am very curious how this tuning result could be achieved on my 25 cal Sumatra 2500, also
The 30-shot bell curve (6 mags!!) is outstanding.
Are there instructions available?
Thanks
Ed

Yes, that was me. And yes, instructions are available. The best such instructions are probably here-
DE-tuning Sumatras and Careers to return a bell-curve power-band
The Korean-made Sumatras and Careers can be so much more than just MAXI-BLASTERS; so I sometimes lament there are no regulators available for them. That being the case, I've become pretty adept at DE-tuning them to realize their potentials as laser-accurate, mere super-magnums. Not an easy chore...
www.airgunnation.com However, I've posted several times about DE-tuning various airguns to return bell-curve power-bands. Thankfully those (other) posts are easily located by using the search function with the key word 'DE-tuning'.
But perhaps the most important part of DE-tuning success might be enough STUBBORN RESOLVE to reduce hammer-spring strength repeatedly, reassembling the gun after each spring reduction to chronograph it, and "lather, rinse, repeat" the process until you find a bell-curve at your desired power level.
Truth be told, my lack of machining skills and equipment are such severe handicaps that my powers of STUBBORN RESOLVE have OVERGROWN to compensate!

Thanks @ AirNGasman.
Here's an LOL for you,
I opened the thread from June 2022 that you linked.
And about 2/3 of the way down found those same questions I asked today, asked by none other than myself.
How quickly one forgets!!
(it was even saved in my bookmarks!)

Me too, Ed!
But that's one of the advantages to being OLDER THAN DIRT
; I don't have to come up with new lies, because I have surpluses of old lies I can constantly recycle. Thankfully most of my friends are equally senile, because they think they're hearing NEW stories if I just change a word or two with each retelling.

Makes me wonder if the dirt you are older than is as old as my dirt.Me too, Ed!
But that's one of the advantages to being OLDER THAN DIRT
Time for a carbon dating adventure!

You know, I just stumbled across an UP North Airgunner video today, where he was testing claims by a company called Cap Dragon that they could double the FPE of the Dragon Claw at stock pressure. And what he found was that somehow, those claims were 100% true. He got slightly over 460fpe which is always going to be relevant when it comes to hunting.

Looking at getting a used Sumatra 2500, are there any common problem areas to look out for ? thanks
