Understanding .270 Winchester Bullet Penetration: Shape vs. Design

Question
do you think the shape an/or lenght of a winchester .270 bullet will affect the penetration depth?

Answer
Not so much shape as it is design.
A soft point will hit harder but a full metal jacket will penatrate deeper. Speed and weight will effect this.
