Bout 20yrs. ago I bought a brand new 7 1/2" redhawk. The best groups off the bench I could shoot was around 12" at 25yds.
I wound up selling it & buying a 7 1/2" blackhawk that wasn't all that impressive either. Sold it too.
Now I've got a 10 1/2" super blackhawk that shoots tacks. Finally a keeper.
