The Hodgdon, Lyman, and Hornady manuals on my shelf all have 357 Max load data in the handgun and Contender sections. I'm getting 2075 fps with 180 Fury spitzers using 20.0 grains of Lil Gun in a 16.25" Contender carbine. I really like these Fury bullets for accuracy, too. Match Grade Machine has 357 Max load data on their website, using their barrels, but it seemed very hot so I've avoided it. I'm getting all the velocity I need to meet the 100 yard energy requirement in CO using the Hornady data. I may get a chance to try this load on a mulie doe next season.
