There’s a lot of Airgunners who’s built some awesome accurate high power .22cal Impact MK2 with PP. Anyone willing to share the parts they’ve used and setting. I know is going to vary in the setting but at least it will put us in the ball park.
Tuning Need Secret Sauce for high power .22 cal Impact

Probably the usual, PP model with slug kit (lighter valve return spring and hammer weight do most of the heavy lifting) Huma or ported brass barrel inlet. Should get you to the mid 70s in FPE with a 700mm. Tuning there's so so so much info out there.

Depends on what you call a high power. 68 Whiskey did a power tune that you can probably adapt to a .22. This is a stock gun, no extra parts. From what I've heard, adding the slug kit gets 20 or so FPS extra and same with high flow transfer port.

Before FX made their own bigger plenums, it was more common to get third party parts. Now that you get valving and plenums in the same package, the FX plenums are probably the most popular. Even a mk1 impact can use the FX plenums.
