I was perusing old articles and came across the January 1969 edition of Guns and Ammo. Inside was an article titled 'Elmer Keith Picks His Favorite Loads'. I found this photo interesting because I've never seen a Keith 38 cal SWC with such a short nose and wide driving bands. Second bullet from the left. Certainly not a 358429.

Later in the article, Keith mentions a "recent" development of a short nosed bullet meant for use in the old short cylinder 357s so the crimp groove could be utilized.

I wasn't aware Keith designed a second 38 SWC. Was it ever offered by any mold maker? I looked thru the older H&G and SAECO catalogs but didn't see anything quite like this one.
