I'm speculating but it may relate to the shape of the slug and the casing size. 70mm vs 45mm
Magnum loads are usually less aggressive. Might be the time allotted within the barrel won't allow for a more aggressive twist. Again just guessing.
Maybe the ratio from velocity to twist is proportional to smaller loads.
