Here is a photo of the cartridges I’m referencing with these questions. First is a typical .38 Short Colt, next appears to be an inside lubricated .38 Short Colt the last two appear to be .38 Short Colt, Short Case (ref - Suydam’s U.S. Cartridges and Their Handguns p.154)
Does anyone know when and why the .38 Short Colt was changed to an inside lubricated bullet from the original heeled bullet? I have one of recent manufacture with an R-P headstamp which has a bullet diameter of roughly 0.355", very similar to the .38 Long Colt and .38 S&W Special. I’m trying to narrow down when this change was made by looking at box labels and bullet shapes. Recent green and yellow boxes seem to have the same load index number for both bullet shapes - R38SC. From the headstamp on my example ‘R•P’, I suspect it’s after the move to Lonoke, AR which I believe occurred in 1986.
Disclaimer: The following photos came from closed online auctions-
Here are photos of the most recent box I could find with heeled bullets. It was shown with a styrofoam insert.
Here are photos of the earliest box I could find with inside lubricated bullets. It was also shown with a styrofoam insert.
About the ‘Short Case’ cartridge - Any idea what the purpose behind this one was? Suydam’s book offered little insight as to why this cartridge was created but I have one with an ‘R-P 38 SH COLT’ headstamp and the short case length (0.668") so it does not appear it disappeared in the 1920’s.
If anyone can shed some light on these it would be much appreciated!
