I've got one just like it, had Steve Young work his magic on it before I took delivery. It's smooth as butter and like yours, very accurate. More accurate than my Browning 92 or any of several Marlin 44's I've owned over the years.
I like it so well that I bought it's twin in .357 and had Steve Young work it over too. This little Rossi is also more accurate than my Browning 92 in 357 or Marlin 1894c.
