Leshiy Classic with (new) Huma Regulator

I think that it is. With my Classic shooting 15.89's in the low 820's and from about a 290 bar fill, I get only around 15 full power shots.

Don't know whether the HUMAs are more efficient or not, but being smaller they leave just a little more room in your cylinder for usable air. Plus yours may now be set at a lower point than the OEM reg. Mine seems to fall off the reg just under 115 bar.

On 100 bar with huma, speed was not stable so i upped it to 125. Now its perfect. Getting less shots btw but very stable. 

I think that's pretty good. I have one that gets around 30 shots at a 250 bar fill but it's only shooting around 20 FPE and that's with the shorter barrel.

As I recall reg is at 95 bar and shooting the 18.1 grain JSB's around 730 FPS. I don't recall the clicks.

I'd say you are doing pretty good at that power in a short barrel configuration.

With my Huma at 107 bar (factory setting) in my 350mm Leshiy Classic at 800fps, I get 34 shots with an SD of 5 with a 250 bar fill. It is quiet, accurate, and surprisingly efficient for such a small reservoir.

I forgot to say that my barrel has 320mm...

And I forgot to post this chart from another AGN member. I think it was @Jack.K but I'd have to go back and look.

I don't know that it was meant to be the definitive tuning for shot count guide but it has certainly been helpful for me when sitting down to start a tune.

With the reg at 100 bar and 11 clicks of the HST he used 7.1 bar per shot. In your case of shooting from 250 bar to 100 bar that would be 21 shots. So I think you're doing well.

Also, I assume you mean 350mm barrel and not 320mm? I do know of one 320mm Classic Leshiy barrel but it was 20 cal. But even if you do mean 320mm you're doing better than 7.1 bar per shot with an even shorter barrel.

Are you seeing spikes in FPS when you come off the regulator?

Cool. What shroud extension & moderator are you using for the in between barrel length?

I assume the Donnyfl baffle extension would be the easiest.
