Don, in reply to your last question: I was shooting 90% patterns with soft shot, fiber wads, and roll crimps in 1961. I have shot 60 yard patterns with 1 1/4 ounces of soft fours that would kill a mallard dead in any part of the 30" pattern. I have killed geese at 70 yards with 1 3/4 ounce ten gauge loads of steel BBs. What kind of "new technology" do I need to have a good hunt? Learning to shoot a shotgun is much more important than busy ballistics. Wonko taught me that.
