I was gifted a few bags of .38 special shells. They are of various makes. Included were some random .357 shells. Just to see if I'm paying attention, I guess. I'm not sure about reloading these odd colored shells. Attached are some pics; including some more normal colored brass for contrast. Does anyone recognize these copper colored shells? Are they reloadable? The headstamp is "R - P", "38 SPL".
