Those seem to be good numbers.
My Diana 470TH is does around 775fps with A.A. 16gr. Pellets for 21ftlbs, and my Diana K98 was at 745fps for about 19.5ftlbs. Haven't run any others lately.

Nice consistency in velocities Bimota. Low deviations mean alot when shooting for groups. You should be tickled with those numbers. Congrats!!

Thanks, I was pretty happy with the numbers. Now I have a
way to track the performance and spot any problems.
Also I put them out there so others could see them.
There seems to be a lot of interest lately in the 30 and 50's.
Between this and the SS tests people can see what they are
getting into.
