I was shooting my fx impact .25 using mk2 pellets the chrony shows me a spread of 15 fps and I was wondering what are you guys getting from yours.?
Fx impact.25
- Thread starter Eddy1840
- Start date
Out of the box with the ST barrel that's what I was getting with the 25grn jsb. Just changing to the STX barrel I dropped it down to 7
Since I "tuned" it to use the 34grn pellets the best ES I have got so far is 18. But that with the 700mm barrel vs 600.

I have the HST adjuster screw maxed out.
These are my current settings. I tuned this rifle with an eye towards using the slug barrel. However, since the .25 slug liners are still several months out I will be starting to retune it for pellets only.
This is shooting 838 fps, es 17, sd 4.5
