I have been doing a lot of research lately on the best buckshot loads and to become a better shot-gunner especially in the area of home defense. In my research it seems that 1 Buck comes off as the best all around home defense round for shotguns. I have read on several different websites that 1 buck offers a perfect compromise of shot count to penetration etc. Why then is it not more common? I have never even seen a 1 buck round in person, My shotgun is currently loaded with 0 buck because I prefer 12 pellets to 9, and I don't see enough difference between .33 and .32 or 54 grains vs 48 grains per pellet to reduce pellet count. If I could find 1 buck it would probably be loaded in my shotgun (considering it patterned well). Thoughts?
