I don't have one, but will try to give you at least an idea on velocity. It will depend on how you load it. If you use standard data with say a cast 260 gr. bullet, Hogdon shows 1067fps from a 7 1/4" barrel. With the "Ruger, Freedom Arms, and T/C Only" data, they move a jacketed 260 gr. bullet 1312fps from the same barrel length. A lead bullet would move slightly faster (less friction).
You'll be looking at velocities in those vicinities or higher with a 10" T/C barrel.
