Why not an 1861 Navy where you have the sweeping lines of the '60 Army with the handling of the '51 Navy? Or get a bastardized '51 "Navy" in 44 cal where you have the balance of the Navy with the whollop of the Army.
My very first C&B back in 1968 was a '61 Navy and it has served me well for years. When I started out in Cowboy Action in the early/mid 1990s many of our pistol targets were knock downs so I used the LEE 130gr conical with good effect. Later I paired up a couple of '51/44s and never looked back. I also shoot Remingtons, '60 Armies, A Dance, etc. mostly in 44 cal. and 80% of them are steel framed.
