FWIW my norm test is at 300 yards for our AR 15s. 10 shots into 2 inches or less. If I can't make the barrel shoot that well it got dumped right quickly.
Not half an inch at 100 but still shows that todays firearms can be very capable.
But it also takes some skill behind the butt too.
And IMHO another poster said smithing skills came along very nicely. IMHO that is true but barrel quality and bullet quality, again, IMHO, have become much more so the norm than it used to be at all.
