Bob- I think 32-20 loads are about 1200 fps and the .327 are about 1600 fps out of a revolver. My seat of the pants impression (i have a 6" Smith in 32-20) would tend to back that up. The .327 made impressive hits on beer cans filled with ice and like I said shout very flat out to about 110 yards. My 32-20 also shoots very flat. I am sure if you had a blackhawk or some other modern strong revolver in 32-20 you could load it up to meet or exceed the .327 performance. Since my Smith was made in 1916 I don't think I will try that
