That's a rabbit hole I suggest you skip for now. Running 140 in Grendel with any powder is going to be a slow bullet that never gets up to speed. It will have a short range of still actually flying above supersonic transitional speeds (i.e not accurate at long range and a rainbow trajectory requiring very consistent velocity and range estimation to hit), and have terminal impacts at below the engineered performance range. Basically, it will be a frustrating exercise at trying to throw bricks. Stick with the 123 or less, is my suggestion.
