Impressive results @Michael. Is that with the stock regulator?
No, I'm using Huma-Air regulators.
Ed does rolling updates all the time... folks just getting Leshiy's will notice that OEM reg is about 1/2 the size. It preforms really well, and adds significant shot count. It now has the estimated lines for adjustment, but if you're a guy who really wants to fine tune and get things exact... you'll need a reg tester. To my knowledge there are not any commercially available reg testers for OEM regs. With that said, the estimated lines on both the HUMA and OEM regs are all pretty close... 5-10 bar range.
Here's my $.02... 99% of the people who do not have power restrictions should leave that reg as is. Keeping it at 120bar you can shoot anywhere from .177 to .30 with reasonable efficiency from 600-900fps. This makes swapping calibers a 30 sec exercise as all you're doing is adjusting the HST.
While fine tuning will help net results like Michael's, it comes at a cost for many... broken valves, chasing leaks from depressurizing over and over, etc. It's counter intuitive, but the higher reg pressure protects that valve.
If you are a person who wants to tinker, and play around with the lower tunes... then I would suggest the HUMA sub 12 kit. HUMA has a reg tester for one, and given the tiny plenum, you really want to be exact with your reg pressure. Michael, you will 100% get more shots with this kit, but yours is shooting so well... I'd go with the if it ain't broke, don't fix it... however you have 2

... so something to think about.
With the Sub 12 kit, I've shot everything with success except the 9mm... that's a different animal. You can easily get up to the speeds Michael is shooting and beyond. If you are using the Leshiy for 50 and in... and want to keep things backyard friendly and safe... this is the route. You combine that with 350mm barrel, and things get crazy shot count wise and insanely quiet, as you're getting about 80fps of free speed (ie. you can tune things down even more to achieve the same result). I've seen tunes take .177 and .22 above 80 shots... I personally shoot the 34gr and get around 45/50 at 500 fps. The 25 kings are around 630fps and get around the same shot count. This gives me 2 options that I can quickly go between using the ATN x sight 4K pro profiles, but if you have a traditional scope, just sticking with the one pellet is fine. I have the stalker and move it around from gun to gun (now on the R5M).
Anyways... something to think about.
