Lead is gonna be FAR better than steel, and bismuth is better than steel...on flesh/bone/game, for penetration. It’s about density of the shot.....steel is the absolute worst. Testing penetration on a steel drum for buckshot penetration on game was a waste of AMMO, unless your gonna outfit your hogs with some medieval armor. 18gcc TSS #2s would probably take a really big hog to catch one. FWIW, EMI (Hevishot company) is FOS regarding about 90% of whatever they promote with their loads. They’ve flat out lied about shot and load composition on several loads.
