i was using old military surplus ammo FMJ 147 gr. i know this is not a hunting round per say but if your just hog hunting, they will take the hogs down. i know the FMJ was designed to injure a human rather than kill a human. the military thought it more stratigic to would the enemy than kill him. if an enemy is wounded it will take his buddies to carry him from the battle field. this elliminates two or more enemy fighters. "push on" my commander said. makes since to me.
