Just wondering by any owners, is the MKII loctited like the MKI? Should I heat it up before turning? Also what setting you guys runnin?
FX wildcat MKII .25 hammer adjustment?
- Thread starter DarkRattle
- Start date
Mine was loctited. I had to get the nut to the point where it started to Glow before it would even think of loosening.
Mine was adjusted to eight and a half turns with the huma regulator set to 150bar.

They do have locktite. Some more or less than others. I would try heat gun or hair dryer first, torch as last option.
Make sure the allen wrench is the right size (5mm I belive)and fits snug. Also if it won't loosen, try tightening it. Usually goes in easier, then back it out.
Hope this helps.

Yeah, kinda wierd. FX does make a jam plate that can be installed instead of locktite, if your interested.

Is that part on their website? When I get my slug barrel I will need to crank up the power.

I just finished tuning a Wildcat MKII Warcat for a member recently, and just like Bob I had to heat it up with my micro torch until it glowed to get it to even budge. I threw it away and installed two new Hammer Spring Nuts in the Warcat... one to adjust the spring and a second one as a jam nut. FXUSA does sell a brass jam nut to be used behind the HSN but I had weird results with it when tuning a friends Streamline, because every time we tightened the brass jam nut the velocity readings over the chronograph changed. So I prefer to just use a second HSN or better yet a drop of Blue Loctite to secure the HSN. If you use any jam nut make a note of your pellets' velocity before and after you install it, to make sure that the velocity has not changed higher or lower because of it.

Good point CHUCK. I have a feeling that the jam nut will tighten the main nut a tad before actually locking them both up. Of course if you had the velocity tweaked before that, any further tightening would screw things up.
I used some Vibratite on mine and it never loosened up. Blue will work just fine as well.

DarkRattle, I tune guns to the owners wishes. Sometimes people want max power and sometimes they just want max shot count. An example of max power would be my own Wildcat which is tuned to shoot the JSB 33.95 Heavy at 915 ft/s for a whopping 63 ft lbs of muzzle energy. I have more energy left over at 100 yards than most .22 pcp's have at the muzzle. Conversely, I just tuned a Warcat for a guy that only wanted 47 fpe but lots of shots. I would set your gun up to at least 865 ft/s which would be 56.5 fpe, or ideally I would prefer to set it up for you at 885 ft/s which is 59 fpe. 820 ft/s is just way too low for you to get the best accuracy and performance out of these pellets. For you to get 51 fpe is too easy...its only about 820 ft/s.

Now is this all hammer adjustment or are you talking a huma regulator set at different pressure?

DarkRattle,
The 34 grain Heavy MKII shoot right at 100 ft/s slower than the 25.4 grain Kings do. So if Kings are shooting at 910 ft/s then the MKII will be shooting at approx. 810 ft/s. Now you may get an extra 10 ft/s by simply adjusting your hammer spring nut...but each gun is different. Try it and see what happens... but a 10 ft/s increase in velocity is not going to do all that much for you one way or the other.

I don't think it "needs" to be a Huma. But they are super easy to adjust to the pressure you want.
But yes, if you want a boost in power, you will need to increase pressure.
