Remember that, aside from Buffalo Bore, all major manufacturers load only rather mild .38 S&W loadings using a 146-48 grain lead bullet. This is because of the millions of old, weak top-break .38 S&W revolvers from the 19th and early 20th centuries still out there which could come apart with more powerful loads. Reloading is the only way to get top performance from the .38 S&W. It is not difficult to duplicate .38 Special ballistics with any bullet type and weight by reloading PROVIDED you fire it ONLY in a modern solid-frame revolver, such as one of the WWII .38/200 British service revolvers, not something like a S&W .38 DA from 1890.
