Our experiences do not align. They never leaded nor failed to wreak mayhem. 3.0 gr Bullseye from a 2” snubby. Primary targets were big toothy fish that did not want to spit my lures out. They will decapitate a 5’ cuda and render 6-7’ sharks dead still...one shot. At any rate, the average heart/lung is only a very few inches behind the ribs. Guts are just below the skin as are kneecaps. Skulls aren’t that thick. Screw 2 holes and tracking.
