My husband was looking at the book by H.W.S. Vol 1 at the section on 45 auto’s. He was wondering if the various blanks and tracers that they talk about are basically all experimentals or vey scarce and found in very few collections.
Some of the .45s in WHS are experimentals found only in the most advanced collections; some are experimentals not found in any collection; some probably never got past the drawing stage; and some are standard issue ammunition found in most collections. The text will generally tell you if the round was adopted or not.
