The 50 (ish) yard shot discussion reminded me of the last dove openner. We had already shot our whitewing limits and were under a cluster of tall cottonwoods in the middle of a large plowed field. The Eurasian dove were flying over at high altitude. Me and a friend only had our 410s. I started shooting 3" #6 shells while he stuck with 2 1/2" #8 1/2s . I started whacking them dead at extreme distances while his shots seemed to miss. After a couple hours of this, I let him in on my secret. He switched and joined the fun.
