Oh, all that happened back in the early 1960's. We were using paper shotshells back then, too. 2 3/4 inch with 9 double O buckshot pellets.
My Uncle Frank was the real backwoodsman. He never saw that guy before the shot, but lost his license anyway. So, he crossed the Delaware River and began legally hunting in Pennsylvania. He often took me with him.
Dad was a casual hunter but a dedicated fisherman.
Anyway, I think OO buck is fine for deer, but only within its limitations. I would not use it beyond 30 yards.
BTW Timberjack, you look a lot like the insurance claims adjuster that came to assess the storm damage to my barn. He said he lived in Polk Co. I don't remember his name.
