Q:

Leshiy .177 to .25

Hi.
I have a Leshiy in cal .177 and a .25 barrel. When I use the .25 barrel I get arround 680fps with JSB king 25grs but I see others get more out of it.
Can someone tell me what is the expected fps in .25 and how many click is normal from .177 to .25 on the tension skrew?

Looks like my regulator is set to 90 bar. It is marked 110 but this shot string looks like 90 bar to me. JSB Diablo Heavy .177
I will try to adjust it a bit up and see if that helps on my .25 barrel

FPS Bar
1. 802 145
2. 800
3. 797
4. 797 130
5. 799
6. 798 120
7. 806 115
8. 800 110
9. 798 105
10. 805
11. 803 100
12. 801 95
13. 787 90
14. 773 85
15. 758 80

My gun shoots flat down to (an indicated) 110 bar. .22 / 15 grains / 795 fps / 250mm barrel

I’ve got Leshiy #58, and the regulator has 130 written on it with a black permanent marker. However, I got the gun from EDgun West, and he assured me the gun would be set to 110 bar. I am under the impression that he was adjusting the guns before shipping them out.

Brian, am I correct?

As far as I know Brian just readjusted it, as it was initially set to 130 (the figures on it). But now I return to 130 bar again with more stiff valve spring.

Is there any benefit from that either in v0 or air efficiency?

Ok, I finally found something related to adjusting the hammer spring. I’m going to tinker with it a little myself as soon as i get a chance.

Check out Edguns youtube channel “The Edgun”

I’m not finding any info on adjusting the hammer spring. Is there a video? or a link?

Thanks

I have opened it up now and the regulator is marked 110…

I would set it to 130 bar for .25.

Hm ok. I think I can try that but I like it as it is when shooting .177.

I would like to hear more about the new settings with stiffer spring. Maybe that is the thing to do?
What is the price on a regulator from you? And regulator tester?

The Leshiy multicaliber if you “act only” on the hammerspring and not also on the reg will not give you the “ultimate power/air tuning” for each caliber but it allows you to swap caliber easily and this is a great feature IMHO.

Ok I will take it apart and see what the markings on the regulator is.

In .177 it shoots really fine. No problem reaching 900 fps and actually shoots good in that high speed. Other guns I have tried in that speed with .177 spirals like crazy at 900 fps

Yes, I adjusted them from the first shipment. When I got the first ones, they wouldn’t go over 680 (25 caliber) The did the typical “hammer spring and regulator, not in harmony thing.” That means that the speed does not fall sharply off the regulator. Some discussions with Wingman and Ed and I changed the setting to 110. Since then I have shot all different calibers through the same gun. The regulator does not need to be adjusted, just the hammer spring. Of course the speed capability between each caliber will vary, for example, the .177 can hit 900 FPS comfortably where the .25 likes to hover around the 770-780 mark. I made that video, just to adjust the regulator one time, not for every caliber

Right now I am playing with the .177 in 10.34 grain. The little gun just whizzes the pellet out.

I have gone over 800 fps with mine in .25 while testing.

With a short barrel? 110bar plus hammer spring adjustment did the trick?

I have the short barrel.

I set about 720 – 740 f/sec with 250 mm barrel. Ask the previous owner if he didn’t readjusted the regulator for .177?

I bought the gun new from Daseshop in Finland. The gun was prodused 17. December 2016 says the manual.
Do you say that the regulator need different settings if changed from .177 to .25?

Just bleed of and remove the air tube check what is written on the regular if bought new should still be factory setting or check with Ari at DASE shop for any modifications before shipping 😛
