FX Wildcat MK3 .22 Compact Question

[fatboy58]

Hi there,



I like the looks & the size of the MK3, and considering buying one in .22. But is it possible to tune it down at +/- 12 - 15 fp/e for when I'm shooting in my backyard ? 

Any one tried this ? And does it still group well at lower speeds ?

Of course is that possible. Just take the JSB .22 diabolo exact. Tune your rifle at 260 m/sec.( 850-855 fps) and you are done !

however in case you have a good backstop you should not have to worry about a bit more or less power .....

succes !

Set the dial to 6 or 7 and then adjust the regulator down until you reach the desired speed.

I believe fatboy58 wants his rifle well tuned shooting in his backyard. By just setting on position 6 or 7 and then adjusting regulator alone you do not get a fine tune. The hammerspring tension ( with hex key) and the weight of the ammunition used has to be involved in the proces in order to get things right for required power output. . I don’t think that fatboy58 is that well into tuning a pcp because of his request but that is why we can help him here in this forum. I suggest to start with a reg setting of 90 bars. Power wheel on 7. Crank up the hammer spring in quarter turns at the time and see what you max speed will be. From there you go back approx 30 fps and then you calculate your power output and check your grouping. I would take a very light pellet like I said and aim for approx 260 fps.

I own the mk2 in 22 (500mm) barrel and the accuracy and consistency is incredible, so much so I bought a MK3 sniper in .25. I've only had the sniper a few days and its showing great promise. Definitely an excellent choice.

Tnx , I mean tuning it down to 590 - 660 fp/s with a 16 gr JSB. Does it still group well at those velocities ? Has any one tried this ? 

The older ST barrels did not group at lower speeds
