Good point...maybe more people need to think of more than just 5.56/.223 when they think AR-15.
The more people that see value in an AR-15, the better. Especially when it comes to fighting for our rights.
I'm also kinda annoyed by people who say you need X caliber for elk, deer, whatever but they are comfortable shooting at distances in which their preferred cartridge has less energy than the cartridges they disapprove of have at more reasonable distances.
I tend to go for a bit of overkill as far as energy for a particular game animal. But you have to admit lots of rounds will work at 100 yards. And you have to be honest with yourself about energy at different distances.
Hopefully that rambling makes sense.
