No, I doubt very much any "social experimenters" will take away your shotguns, Don. It would take votes, and for the foreseeable future, you have the votes. Yes, you can hunt... it will not even worry me.

As to the Constitution, it is a bit ambiguous. But even if we could call up the framers and ask them what they meant, and IF they agreed with you, I'd sure be interested in what they'd say if we explained to them how the country & the world has changed in 250 years.
Both the need for a "militia" in the 1789 sense, and the type and power of weapons has changed. The Constitution needs amending to account for changes in the world....but not even you sane, honest gun owners will vote for allowing any changes.
