Another similar load that I really like is 8.0 grains of Herco.
A major +1 for Herco, it is superb IMO for cast .357 rounds on the medium-warmish side.
But if I wanted to replicate or semi-replicate 2400, I would purchase the stuff myself if I didn't have it in stock. I love 2400 for the .357 hotties, the fireball is splendid.
