The facts and your own description are the proof.
Sectional density of 0.143 with a bullet weight of 250 and diameter of .500".
Large hollow point
Soft lead
How else is it going to react when shot much faster than a 50A&E?
Its not, its going to react just like a varmint bullet as indicated by your first post. There is a reason not a single ammo company offers a 250gr 50cal copper plated bullet with a huge hollow point. People typically dont want a varmint bullet in their 50cals.
