Allow me to…
bore you with some numbers… 😆
Blod valve with selphb stem.
18″ barrel.
Have lightened my hammer to 49 grams.
Fill to 2350psi
Power wheel…whats a power wheel!! 77mm hammer and spacer combined.
Bisley Magnum .22 21 grain.( Same pellet as your Kodiaks)
904 884 840 920 929 931 941 938 923 933 928 939 939 934 938
937 947 943 946 947 err 948 947 952 949 934 939 938 933 939 927 924 922 919.
End psi=1650psi=700psi used at 20psi per shot.
So my next fill will be 2300psi to get rid of those first 4 low shots to give me 30 good shots. The string is not quite as tight as I’d like, too loose for reliable 100 yard shooting, but should be ok out to 75 yards.

I like numbers…they tell ya lots of stuff 😉 😉 ……if you got rid of the first 4 (low) shots…would you have any change in your POI from your high to low variation?? Looks like the high would be 952 and low would be 919 difference of 33fps– enough to change your POI at 75 yards??
That shot string look’s pretty good to me!

Those are pretty good numbers. Might be a little difficult to tighten up without a regulator, or do you have one?
