The round in the chamber rule is ridiculous IMO. Every round in the chamber is not necessarily going to be fired at an animal. Trying to read people’s minds is a great way to justify stepping over the line. It’s unwarranted.
These government busy bodies, need to find something else to do with their “talents”.
I'm quite sure that “3 rounds in the chamber and magazine combined capacity” rule is from the federal governing body that sets rules for migratory game birds ( ie..ducks , geese, etc) and many years ago was requested by the duck hunters themselves.
When market hunting for waterfowl was outlawed, hunters wanted some of the old methods outlawed that they didn't feel should be used for sport hunting for waterfowl.
The three shot rule was put in place to control “sky blasting”.
