Anybody know what the lowest power you can get the Leishy to by simply adjusting the hammer spring tesioner? (talking about the full power version not the 12fpe restricted version)
Edgun Leishy Lowest Power Setting

thanks brian - so thats 0.25 25.39g at 510fps = 14.67 fpe - so guessing you would need the restrictor to get it below 12fpe or reduce the regulator pressure.

My Leshiy is currently consistent 22 shots at 790fps (ES6, SD1). However, I consider tuning to lower power (600-650fps) due to small backyard shooting. Do you recommend how many bar HUMA should be?

You can turn the regulator down . If you're shooting the Leshiy in a country that has a 12 foot pound requirement you should use a TP restrictor. The other option is to use a 12 foot pound Huma
Kenny for you if you want to shoot 12 foot pounds for backyard shooting just turn your regular Huma to 80 bar. When the gun falls of the regulator you will get a speed spike but it doesn't manner for you because no law will be violated

As Brian said, depends on the regulator and HST setting.
When I first got my Leshiy (.22, shooting 18.1gr JSBs) I installed a Huma at 110 bar using the stock hammer spring and plenum. 0 clicks on the HST was 550fps (12.1 ft-lb), 10 clicks HST was max regulated velocity at 775fps (24.1 ft-lb.)
I bought my Leshiy mostly for ratting at night, often inside barns and shops, so I didn't want a ton of power. I bought the Huma 12 ft-lb plenum and spring kit so the rifle would be more air efficient at the low muzzle energy I wanted. I also bought a spare valve to cut down for the shorter 12 ft-lb plenum kit.
I installed the lower power hammer spring but did not install the plenum volume decreaser. The plenum volume decreaser is used for 12 ft-lb applications to avoid a velocity jump when falling off the regulator for countries like the UK where that can get you in trouble. I wanted to be able to turn it up a little higher than 12 ft-lb when not ratting inside buildings, so I did not install the plenum insert. I left the regulator at 110 bar.
With the 12 ft-lb plenum and lighter Huma HST backed all the way out, the rifle shoots 275fps with the 18.1gr pellets -- 3 ft/lb, LOL! It's stupid quiet and you can easily watch the pellets fly to the target.
At 27 clicks HST, the peak velocity of the 110 bar regulator/12 ft-lb plenum combo is 710 fps (20.2 ft/lb)
The stock HST is quite strong for the lower regulator pressures, so the minimum energy at 0 clicks HST was much higher and it only took 10 clicks in on the HST to hit the maximum regulated velocity-- not a very wide adjustment range. The lighter Huma hammer spring allows a much lower initial energy with the HST backed all the way off and a much broader adjustment range with the lower regulator pressures and small 12 ft-lb plenum.
