Trying to get my 25 & 30 impacts tuned to 34 and 44’s. What velocity have you found to be the most accurate at 100 yard BR shooting out of a 700 barrel?
Please share your 25 & 30 Impact velocity

I can only speak for my gun with a slug liner in 25cal , the jsb 25gr is best @860-880fps I believe is do to the shape. However the 34gr shoots great @930-950fps and perhaps even faster. I have reached my lmpact mk2 max and is tuned for the nsa36.2gr @915fps that’s shoots very well. I hope that helps you.

So far my Impact X in .25 (700mm barrel) seems to like shooting 34gn MKII’s around 890-895fps. I haven’t tried in the 900s yet just to save on shot count. If I upgrade the plenum to a Power Plenum that may change.

30 cal Impact updated to MK2 heavy hammer ported inlet shooting 43.8 slugs @ 910fps getting under
1/2 inch groups @ 50yds still can shoot pellets in new liner by dropping FPS to 870 power wheel setting
down to 4 no other changes.
