Hi,
What is the optimal speed for L1 with a 350mm barrel shooting JSB King pellets? I was thinking about 880FPS.
Thanks!

I guess it depends on what your goals are. Short range pest control, long range target shooting, power over precision, or shot count.
I can't help you with the .25 but I have lots of experience with .22. Since the L1 is so light I found it more pleasant (and accurate) to shoot at lower power. I had mine tuned for 20 FPE. 250b fill, regulator 80b, JSB 18g, Ave 723 FPS, Ave 21 FPE, 38 shots.

That’s up to you. If you don’t mind your PCP feeling like a springer you can get some velocity out of a Leshiy. My dad currently has mine for some larger pest removal. Mine is a .22 shooting 18gr. I had to put my 350mm on it to get around 850fps and keep the gun nice to shoot. Best advice is start your tuning around 700fps. Then just increase the speed across the chronograph. You will feel when the gun starts getting ugly. Once you know that speed, then do a proper tune centered around that speed. A tell tale sign that your quest for speed has gone too far is the gun starts jumping to the left or right when you shoot. I can’t remember which way it jumps but it makes being consistent with the gun a real pain.

A lot of people say left but what I find is that my groups start to form a horizontal line when I take my Leshiy too fast. If anything it's more likely to be to the right of zero than to the left for me. But maybe it's how I shoulder it. I've heard a stronger spring can help but I prefer a lower power tune anyways. I agree that around 20 FPE in 22/250 seems to be a sweet spot.
Not knowing what the OP's goals are I should add that my first Leshiy was sent to me with a reg setting of 130 bar and the HST turned nearly all of the way counter clockwise. Seller mentioned a poor shot count but that's about it. I'll just say that that Leshiy has been problematic for me so proceed with caution.

The hinge is on the left side so the front will swing to the left - if pushed too hard the breech o-ring will expand and the spring loaded latch will not be able to keep the breech fully shut
Here's an example, if you look closely you can see the breech open a bit

..and then you will find horizontal slide marks from the valve stem on the surface of the hammer (not the best picture)

A Leshiy is a perfect example of just because it can do do something, it doesn’t mean you should. Lots of Leshiy second hand owners get stuck with guns that had the piss pounded out of them because the gun could. Listen and feel the gun, it will tell you where it’s happy. If you want big power in a small package, buy a bullpup.

My Classic in 25 cal is at 860 fps for 42 fpe with Hades 26,54gr pellets My Leshiy 2 25 cal is shooting 754 fps at 42.9 fpe with JSB Heavies 33.95gr and Hades 26.54 at 770fps for 35 fpe still experimenting with the L2 just got it probably gonna up the reg to shoot Hades in the mid *800s Both guns Stack em out to 35 yds and have plenty of bodies on them
