Ditto to Jerry,
Just about all my .22's shoot the Federal Bulk Pak really well. I have not had good luck with the Winchester Dynapoints in my rifles, though, and some folks swear by them. I think you will find the Single Six is not quite as accurate with the .22lr as the magnum since the barrel is sized for magnum which is slightly larger. I have shot a lot of the CCI CB's in mine and they are deadly on the wild possums around my house. Super quiet, too. I also put Hogue grips on mine because I like the larger grip. Same grip fits it as the Blackhawk, believe it or not.
