i used a lightfield slug this year and it dropped my buck on the spot. It destroyed both lungs and the impact broke the spine. theslug never passed through.
having a shot not pass through is not necessarily a bad thing though. F=MA. if the bullet slows down enough on impact to not pass through, that means more force was applied because it had more deceleration. If a bullet passes through, it does not apply its full potential force.
your absolutley right, however its all relavant. its much harder for a slug traveling at 2000fps. to deliver all of its kineticenergy, [ie. by notpassing thru the target and/or shedding mass (bullet weight retention)], than saya standard velocityslug traveling at 1500fps of equal mass. Also, bullet mass and downrangevelocity ultimatly the deciding factorenergy upon impact. you can also get into bullet design, how the bullet expandsat any given velocity.
