I recently bought a mid seventies Single-Six off a friend. Its in really great shape and it is quickly becoming my favorite revolver. After I purchased it I went to my LGS and bought some CCI TNT WMR and wow what fun! It looks like shooting a .357 magnum but without the recoil and a great fireball. Makes me smile ear to ear like a kid. I asked the previous owner if he ever shot the mag cylinder and he looked at me like why would I do that? I have also talked to a few friends that own them and they never use it either. I realize its a few bucks for WMR but I always leave some in my range bag for other shooters to experience.
