My 2 cents. A fella (ex H&H actioner) I spoke with abt 20 yrs back said:

1. "created" and ordered by a rich dentist because he had to have something different.

2. Wilkins (?) was understood to comment that it was an unherently unsatisfactory round (see above on penetration etc)

3. Became a "must have" for those less informed. (fantasy gunsmithing)
