Leshiy tuning tricks
I thought I would start a thread where everyone could share their tunes. The gun can be adjusted by just the HST but to get top shot count you should adjust the regulator to the pellet weight and HST.
I’ll start:
.177 10.34 grain
250mm barrel
290 BAR Fill
Huma regulator
Regulator setting 95 bar
Max HST speed 825
Low 760
45 shots at 770
37 at 805
Best ES at 805

220 bar fill 7 Shots.
-jsb king heavy mk1 221m/s.
-grizzly 225m/s.
-jsb(1,645g) 249m/s.
Shots per fill at what fill pressure?
huma reg (135bar) .25 .250mm barrel
-jsb king heavy mk1 221m/s.
-grizzly 225m/s.
-jsb(1,645g) 249m/s.
Ok thank you. I was av bit confused When you said hammerspring but now I undestand :smilen:
My huma reg is on its way so I look forward to try with that installed
Heres a look at the “VALVE”(not hammer) spring spacer, Ed added this in the newer guns to put more tension on the valve spring which restricts the air flow in the lower pressures once off the reg and gets better efficiency and consistency with a 130bar reg setting instead of the original 110bar setting.
Earnest calls it a “hammer spring” twice too but it is the valve return spring.
Awesome thread! I love this gun and the ability to adjust it. Being my first pcp I am trying wrap my head around all the numbers, But in my testing this is where I have landed.
.177 10.34g
250mm Barrel
Stock regulator set at 120 bar
+10 Hsta
Average 833 for 21 shots.
SD 2.6
ES 9
Why the hammer spring spacer? And how is that done?
oops sorry, added
Keyser, what pellet weight is that?
Here’s a good tune for the 250mm .25cal barrel with the Huma reg set to110Bar, 700fps with 25.4gr kings, 27 shots
Valve fitted with valve spring spacer. 250 bar fills

Hi all,
So today I had about an hour to play with my new Leshiy… only got to play with the 250mm 0.177 barrel
After some very usefull advice from Wingman this were the results:
Gen2 Leshiy(with new stiffer spring)
Huma reg set at just below 100bar
Jsb 4.52 10.34 gr
HST set at the 16th click from min
I got 19 full power shots before pressure going below the reg. Pressure range 220-100 bar
Average velocity 850fps with only 6fps extreme spread
I think I am very satisfied with this… what you think?
Now accuracy wise, I cannot comment since I only have 9 yards in my basement and it was one hole shots from that distance…
