I have no idea where Hodgdons came up with their min and max for .357 trailboss loads. I use "their" formula and came up with completely different loads then theirs. Hotter for the record. Using 158gr Berry's plated bullets I came up with 3.5-5.0. Hogdons listed 3.2-4.2. I tested various loads using these bullets from 3.2 up to 4.7 without issue. Note: Bullet seating depth is the issue. Don't compress Trailboss and don't go below 70% and you'll be fine.
