So a 40gr Vmax is a better at punching through car doors than say a 75gr TSX?
I see your attempt at derailing the thread, but the fact is - yes that is correct, other than the fact there is no .223 75gr TSX to compare with your 40gr Vmax. Assuming you mean the 70gr TSX though - yes, a 40gr at higher velocity will punch through thicker steel (or aluminum) plate than a slower 70-75gr bullet. That is the opposite of what they do in meat where the heavier bullet usually can penetrate better.
