FX Fx m4 tuning .22 slug 30gr

[Salmulla]

Hello,

Does anyone shoot fx m4 22 slug 30gr @ 100yards - out of the box

Appreciate if you can share your velocity, regulator pressure, macro and micro for a reference

I am using a sniper version with H&N hp 2 slugs 30gr

Thanks,

Not 100% out of the box but I shoot 30gr HN out of a .22 heavy liner (700mm) at 900 accurate as hell. 130b, HF TP and pin probe, micro a little under 4 3/4, valve adjuster 3.5ish (can measure properly if needed). Didn’t want to mess with the tune since it’s the same for my .25 barrel with 34gr pellets and slugs, but 900fps in .22 was/is plenty fine.
