No way that 2 3/4" 20ga Buckshot kicks as much as 2 3/4" 12ga Buckshot. Havng gone from a 20ga to a 12ga ten years ago, I am considering going back to the 20ga. I can shoot the 20ga all day long, and recoil is only an issue if I sit down while shooting slugs. It doesn't seem that there's a lot of love for the 20ga for HD. I'm sure that at close range, the bad guy won't know the difference. The difference for me is less blast, flash, noise, recoil, and faster follow-up shots. I think in HD, rounds on target matter most, and that too many people who can't handle a 12ga end up shooting that gauge, but not enough to be proficient. 20ga shells are about the same as 12ga in price, and the cheap buckshot out performs the cheap 12ga buckshot. For one, its all buffered. Every factory load has that plastic buffer material between the pellets. A lot of people mention the .410, and I have considered it, but I am curious as to what kind of shot deformation you get out of those buckshot loads. Are patterns very consistent? I am in the process of extensively pattern testing factory buckshot and hope to post my results after I finish patterning all seven factory loads in 20ga.
