I'm happy with the Chrony.
As was said, I'm good with what I paid, and it's to see if my loads are near where the book says they should be, with all factors involved.
Shot the same loads over it twice now, and same velocities.
Are they accurate ?
Using JBM, and the mil marks in my 10x mil quad super chicken, I smacked a soccer ball sized rock at 580 yards !
Is my old Leica lrf 1200 accurate ?
Another questionable factor involved....
