You seem unable to provide velocity for your load but if it is anything over 2,750 fps then your load is too hot. This may be from the powder or the Norma cases may have less capacity than the Winchester cases used by Hodgdon. In short if your velocity is over 2,750 fps then your loads are almost certainly too hot.

Velocity is 2820 fps, when looking at book data wouldn’t that be for sammi spec OAL?
