Colt revolvers, that are chambered in .38 Colt New Police or .38 Police Positive, which are identical to the .38 S&W except for a slight flat on the bullet nose; have tight bores (.356 groove diameter) with chamber throats at (.358) and work fine with regular .38 Special bullets.
Factory loads, and matching hand loading data offer modest performance (I use the term loosely) because of 19th Century relics that folks are determine to shoot. In a S&W or Colt Hand Ejector as well as a 20th Century Webley or Enfield you can safely take up the charge a bit.
World War Two S&W .38-200 Victory Models are supposed to have barrels with .361 groove diameters, but don't bet on it. Most run closer to .358".
