FX Wildcat 25cal and JSB Heavies Max Speed and Shot Count

[jking]

My 25 Wildcat shoots the 25.4's terrifically and I don't know how the heavies could be much more accurate but I've always got that thought in the back of my mind about what could it do with heavies at max velocity and decent shot count. Has anyone ever increased the regulator pressure to find this out?

Nope, never played with the regulator on my WC. She is grouping in a half inch with the 25.39 gr JSBs (when I do my part) at 65 yards ... I ain't about to mess with perfection.

I have taken my regulator out to replace the o'rings before but never intentionally tried to make adjustments to the regulator. Plus, one wouldn't know what their output pressure is unless they have a gauge attached somehow. Ernest Rowe built a device to read the output pressure of the Wildcat regulator and he's the only I know that has this tool.

Here's a link to ER tuned Wildcat .25. He increased reg to 155 bar, heavier hammer, achieved 880 fps avg. with Fat King 34 gr. With 28 shots on the reg.

That build he reported inspired me to send him my Bobcat .25 for his tune in July 2016. Shoots Fat Kings MK1 @ 881fps and the MKII @ 888 with 44 shots on the reg on a 250 bar fill of its 470cc cylinder. I specifically chose to hot rod the Bobcat vice Wildcat due to its larger air cylinder, heavier weight to control the muzzle flip of 59+FPE. Love the Fat Kings! Accurate and bucks wind at longer distances than the Skinny King .25gr and drops in more FPE at the target. At this state of tune for my Bobcat, it shoots the Skinny Kings hot @ 971fps and still accurate.

Think I'd be inclined to install a Huma reg set to 140 bar and go from there. Believe they are more stable and efficient than the factory reg and much easier to adjust without a reg tester. May have to increase hammer weight, testing will tell. You may have seen these similar threads but if not, take a look.

I’m thinking on getting a HUMA reg just in case I get the urge to shoot 33/34s. Easy R&R in the Wildcat...

Thanks for the input guys, I'm kind of inclined to agree with likkitysplit, "if it ain't broke don't fix it". I've had the regulator out of my 500 Royale a few times but I've never broke the seal on the WC. I don't know that I've actually seen a video on it either. I think with the air tube size the WC has its suited to shoot the Kings perfectly. If it had a 400 or 500cc cf tank I'd be more inclined to try boosting the power to shoot the heavies. I'll leaver B.

I have a kalibrgun Cricket turned by Ernest Rowe and it is amazing I cannot say enough about his Tunes.
