My favorite 38 Special bullet has been the 146gr SWC. But that weight/profile seems to be hard to find these days. So now I use 148gr/.357" dia DEWC from Missouri Bullet Co. I like these for plinking and also for 'target' loads in my S&W Mod 52.
I also shoot their .453" 200gr "Oddball" LRN in my .45's.
Both of these Missouri Bullets have Thompson's Bullet Lube lubed cannelures.
