Good day. I’m new the the pcp game. Just got my self a m3 impact compact .25. Currently shooting jsb hades 26.54gn. Trying to find the best tune and speed to focus on. Any help would be appreciated. Thanks.
FX M3 impact compact .25 tune
- Thread starter Zonkjz
- Start date
It will shoot a Hades over a very wide speed range with adequate hunting accuracy. One guy will tell you 885fps, another will tell you 920fps and just when you think you made up your mind a guy will post pictures of his micro 50 yard groups at 940fps. So welcome to PCP’s and the M3. Start testing and figure your gun out.

What @Vetmx is saying is too true, I would consider the fact that you have a compact which means you won't get that many shots. So I would start with a speed around 830fps if you want the highest available shot count and work your way up from there. If you don't care about the shot count then do as you please lol.

use a chrono,and watch the ernest impact tuning vid.
i have a compact .25,
at one time i was running 34gn jsb at 870fps getting 50 shots a fill.
another time i setup regular 25gn kings at 900fps for 75-80 shots give or take a fill.
i can switch pellets/speeds and tune in 15min,
and use less than a full magazine of pellets to do it,
learn HOW to tune it,
and understand what the adjustments actually do.
the impact is very simple to tune once you understand what the adjustments do.
the macro and micro adjust knobs do the exact same thing they just do it in different increments
(both merely adjust the hammer spring tension)
the valve adjustment under the bottle is used after setting the hammer spring adjustment,
it has a bumper in it to help the valve close faster after the blast of air,
which translates to less wasted air after the shot, and a quieter gun.
