I don't think anyone is disputing that. But are you telling me that a semi-automatic rifle, with a 100 round magazine (which is what I believe he had), wouldn't be able to kill more people at a faster rate than a bolt action rifle where you have to load the round manually each time and carries only a handful of bullets before you have to stop and reload?
All you have to do is pull the trigger 100 times, versus:
pulling the trigger, loading a round, pulling the trigger, loading a round, pulling the trigger, loading a round, etc. then stopping to reload....
I'm not necessarily backing one camp or the other, I'm just trying to clear up why people are targeting this weapon over a bolt action hunting rifle. It IS easier to use and, in this configuration, would easily fire more rounds than your average hunting rifle.
