Shmackey,
Time:
Late '70's--IMHSA was gaining in popularity as a new sport.
Problem:
.357 mag revolvers lacked the 200 meter punch to knock down the targets.
Solution:
180-200 gr slugs @ 1700fps +
Platform:
Wasn't Smith or Ruger--they fell apart from a steady diet of 50K psi .357magnum loads.(Colts were out of the running)
Guess I'd have to say Dan's = legendary.
Agree with uglygun,,,Dan's have a funky D/A trigger,,no question about their strength though,,,toughest muthas ever,, far as revolvers go. Maybe a Redhawk or a Raging bull are at the same level,,hard to say though.
