FX impact Mk3 .177Tuning
- Thread starter iisparky7
- Start date
The only little nugget I can offer is high pressure and short valve timing.
I thought I had a bad liner and wasn't able to get much accuracy at all until I had the reg up to about 150 and the hammer somewhere in the middle range going about 50 fps too fast, then I turned the valve limiter down to reach desired speed. Once that was sorted it was outstanding!
Sadly, I sold that barrel setup to go down the .22 slug rabbit hole, and here I sit at the bottom of that hole! it works great but it is temperamental and expensive. A .177 Impact is a great combination.
YMMV.

It depends on the pellet and what speed it is most accurate at, but a good starting point is between 850 and 1000 fps. Any faster will usually result in poor accuracy with pellets.

Can you tell us a bit more about you current setup?
Barrel length, reg settings, hammer wheel, micro adjuster and valve adjuster.

Do you have a chronograph? That is the only way to know the speed of the pellet.
There are cheap chronographs on Amazon for $30 all the way to $1000 for FX's new radar.
Whatever model you use, pellets seem to like speeds between 800 to 900 feet per second.
Enjoy the rabbit hole and good luck!
