R5M 34 grain tune (long)

EDgunWest · May 3, 2018

As promised I worked up a Huma power tune for the R5M long in 25 caliber. I was able to get a legit 48 shots from 210 bar @ 912 FPS. The platform is amazing and still the most powerful pellet bullpup for its size

Set your Huma to 130 bar. The regulator tester is really a good tool to have. The sticker is just a guide For this kind of work you really need to be precise.

So how was the accuracy through the R5M at 912fps.

I will make a video showing accuracy. This is not a new system, I beta tested the R3 with it, just the R5M no longer needs a hammer weight

Brian,
will the regulator testor work with the Huma in my R3m magnum and my Leshiy. When you do the video on the Accuracy can you also do a comparisons on what the different length rifle will do. I’m thinking of getting one but I have no idea on what length would work for me.

Hey Brian the regulator tester works with all Huma regulator except the ones listed listed on the project page
Brian

You want a power comparison? I will do it when I get new stock .

Brian,

You are a master! I am at 915 fps and can also get 48 spf... but not from a 210 bar fill. There is still more potential to tweak additional efficiency out of mine. You are forcing me to adjust again.

This is my new R5M Long .25, it was tuned for shooting JSB 25, with the Huma reg at 120 BAR (without the tester) shooting at 877fps avg.
As soon as I have it in my hands I'll report with more info and pics, just a few hours more !!!!
The target was at 45 yards.
