View attachment 788669View attachment 788670Anyone interested in the topic of 38 Special wadcutters would do well to seek out the ample published data that was written during the era in question.
The constraints of time and space, not to mention forum policy regarding copyright, do not permit replicating that information here.
As a good place to start, look for work written and published by Gil Hebard (his Pistol Shooters Treasury is a must read), and the series of articles written by Al Miller for Handloader Magazine in the 1970s.
Try the search engine provided on this forum to find a few tidbits.
Beyond that, another suggestion is to research the Star Universal Reloader tool, the Star Progressive Reloader tool (which was ONLY made for 38 Special) and the details in how they were set up, the loads they were assembled to replicate, how they were intended to be used (specifically with the recommended Hensley & Gibbs molds), and the results obtained.
The Star tools were the Gold Standard for serious reloaders and target shooters from the 1930s until the company closed its doors around 1990.
Today there is, not surprisingly, a website & forum dedicated to Star tools.
Match grade wadcutter ammo, as offered by Remington, WW, and Federal back in the mid 20th century, was of a higher quality than what is now sold (a sad reflection on the current state of what passes today for pistol marksmanship in America).
The competition was fierce not only on the match firing lines but also amongst the manufacturers.
In addition, the factories used canister grade powder that was not sold to the public.
(Since forum folks here like pictures, I included the somewhat relevant photos shown above….both 38 wadcutter shootin' machines of the mid-20th century.)
