Hello everyone, first of all, encouragement for this situation for the Covid19.
I have been reading this great forum for a long time and learning a lot.
Today I received and installed the power plenum for wildcat mk1 with huma regulator at 130 bar shooting 18 grains at 900 fps, after the installation of the power plenum everything remains the same ... any suggestion? Thank you all and cheer from Spain

I have a Wildcat MKII .25 and have also installed a Huma 30cc plenum as well as a Huma regulator. Also set at 130 bar my power increased from 950 fps to 980 fps with JSB 25.39 King’s and from 840 fps to 890 fps with 33.95 King Heavy’s. My shot count is the same but as mentioned my power is greater. I have not changed any tune settings, only installed the Huma plenum. I love the gun as it is now, it is one of my most accurate long range shooters! I believe you are absolutely on the right track. My advice is to leave it right where you’ve got it, 900 fps is perfect for JSB 18.13‘s. Although if you wanted, you could increase or decrease your hammer spring tension for more or less velocity if you cared to do that.

Has any body used a Wildcat with the Huma PP with slugs? My older Wildcat with the non X barrel system has been gathering dust for close to a year. I've got a Huma reg (not installed) for it. Was thinking about getting the power plenum before starting the slug search. Is it worth doing this without the slug barrel?
