Fun fact: despite Texas’s reputation of being heavily armed, there are almost zero places for gun owners to actually shoot outdoors. Compare that to blue states where that are usually a lot of public land that you can drive to, put up some targets, and shoot for free 24/7 (except when there’s maintenance or closures due to disrespectful assholes).
Essentially, unless you’re rich and own land or have a buddy who owns land or willing to shell out fees every time you shoot outdoors, most texans just own a bunch of guns and shoot in a fixed position at indoor ranges.
Obviously you can still be lethal from basic marksmanship, but the romantic imagination of Texans holding down the fort during a civil war is just that - imagination. Most of them have no better training than your meemaw who shoots a gun every few months at an indoor range, 1 round every 20 seconds because anything else is considered rapid automatic assault fire mode.
