I not a fan of max loads and according to the site, I am over max at 5.4. Speer #14 has a start charge at 5.6 and max at 6.2. Lyman #49 starts at 5.2 and max at 5.8. Hodgdon (most similar bullet) starts at 4.2 and max at 5.3.
For my Kimber, I worked up from 4.2 to 6.0. All brass was recovered with no signs of over pressure. For my pistol, 5.4 gave me the most consistent velocity.
