Where did you get your data.
Nosler list a Start chage of 5.1gr and a max charge of 6.1gr at 1.120 OAL.
You are below minimum here not mid-range.
Alliant list only max at 6.4gr. They instruct the handloader to reduce this Max charge by 10% for a "Start" at 1.120 OAL. That would be a start charge of 5.7-5.8gr. You are well below minimum here as well.
