So I’ve had this draw case for some time now and was wondering if we had any resident experts on experimentation with +P .38 Special loadings. What companies/people/manufacturer were involved, early examples of headstamps, etc? I have tried looking into +P .38 special, but haven’t dug up anything that can’t be found readily on Google.
This case appears to be a few millimeters longer than a standard .38 Special case, but has signs it may have caused a stoppage when being trimmed. Primer pocket also has not been punched through and the rim is very rectangular when viewed from the edge (doesn’t have the typical bevel of a finished rim).
Any insight or experience is appreciated!
