op, here is the buck n ball you bought and so did i after watching this video:
i have the buck n ball in my second hd shotgun, first hd shotgun is loaded with regular 00 buckshot.
that same guy made videos of 00 buck and slugs. the buck n ball wins imo. it has much greater penetration(and damage) which is good for my hd shotgun #2.
2 3/4 slugs went 10 or 12 inches. about the same for 00 buck. 19 1/2" for the buck n ball.
