Welcome to the forum!

I believe there is an earlier thread on this- you might want to do a search. I too have been fascinated with these loads for many years, have read all the negative comments- probably true- but ALWAYS buy these 200 grainers whenever they sometimes show up at gun shows, unless ridiculously priced. Buy the Remington version also. They were written up extensively in General Hatcher's book, "Textbook of Pistols and Revolvers"- 1935.
Great nostalgia!
