All i can say is there is NO perfect cal. Bigger bullets doesnt mean anything. My friend's dad was hit several times in the chest by a Yugo M67 7.62x39 projectile which has about 1500ft-lbs. He was shot under a 100 yards. All bullets hit him in the chest, center mass. This bullet does extensive damage when it yaws, after about 7in of penetration. He was shot multiple times and left for dead in the field for a few days. Today he is perfectly fine except he has no feeling in his fingers.
