Familyop, a few observations on your comments. I have two lever action .30-30s; a Winchester and Marlin. Both give me groups of 3 or 4 inches at a hundred yards over iron sights using a rest (my range limit). I do a bit better with my K31 which shoot a spitzer bullet (7.5X55) and is heavier. I would be very interested to see what sort of a pattern your Ar-15 (.223 or 5.56) gives you at 400 yards, particularly if there is any wind. I don’t like rifles with high lines of sight.
Those are good groups with a 30-30 at a hundred. Well done! A lever action can be pretty fast, too.
I was only trying to say that different people might have different terrible situations on different kinds of terrain, and that we, as Americans, shouldn’t be limited to older firearms designs, including for home defense.
As for greater safety enhancements to keep people from using weapons to violate the rights of others including police, the greatest would be to get firearms out of the hands of most of the drug abusers. Drug abusers are more incompetent than the village morons of early America, and histories of drug abuse are often omitted by the media in publications about murders. There’s far too much tolerance for drug abuse and for the mental illnesses and criminality caused by it.
