MCB; what a revelation! To be honest, I don't follow a lot of 'trends'. I have a group of cartridges I use and tend to stay with them.
If I recall correctly, the .38 Special, et al, was based on the .38 Short Colt. That was the round decided to be ineffective against the Moros in the Philippines. It was chambered in some of the revolvers of the 'old west', but seems to be missing for a long time.
I am a bit surprised it has been resurrected for revolver games. At the same time, I'm not so surprised. It seems to make the power requirements - if any - in various categories. Moon clips? I use .45 AR in revolvers to avoid moon clips. Then again, I don't play games.
I do have a revolver in .38 S&W. It started life as a Victory model S&W, but somewhere has been 'converted' to .38 Special and the barrel cut off just AFT of the ejector lug. I bought it years ago as it was cheap and looked so lonely and sad. Never have shot it.
I have several .38 Special revolvers and am working on a 200 grain bullet load, for self defense against ruffians and thugs, not barricades nor automobiles. Just about done. Seems to work.
