No first hand exp. but here is what my buds had success with. Not one bad exp.

One of the guys that I hunt with did in his gobbler at 40 paces this year with HS 20ga. He was happy with the preformance and shot it though IM choke.

I guess he counted 8 pellets/holes in the head and neck. Good' nuf. I can' t see why I would NEED more that that for proof of exceptional preformance.

PS Two guys that I know baged 18 Canadian Honkers this past fall with HS 20ga. They Both were VERY impressed with the penitration on wings and body shots.
