This will bug alot of folks here but...
1, I've never shot an AR that was up to my standards when it comes to reliability.
they couldn't make it through a range day without a jam, FTF, or having problems with magazines.
other than that:
2, Never shot a full auto
3, Never shot a Mil Surp.
4, Never shot a battle rifle chambered in .308 .
5, Never fired .17HMR, 10mm, .40, .270, 7mm Mag, .300 Win Mag, .338 Win Mag, .25-06, 7mm-80, .454 Casull and more but it would take too long to list.
6, Never owned a 10/22. Probably won't.
7, Never shot a Panda bear.
8, Never shot beyond 200 yards.
9, Never shot anyone or myself (airsoft and paintball don't count do they?).
10, Never liked or wanted to own a pistol caliber semi-auto rifle.
That should about do it...
