Exactly. A round of .223 or 5.56mm is not “high-powered;” in fact, it is underpowered enough that several states ban it for hunting deer, which are in the same weight class as people.
But why should an article on firearms be accurate?
These Left-wing @ss-hats just write their own definitions. For example:
rimfire ammo = "deadly"
centerfire, too anemic for hunting = "high powered"
traditional hunting rifle ammo = "super high powered"
magnum rifle ammo = "mega-super-dooper high powered"
exotic cartridges (.50BMG, .338 Lapua, etc.) = "weapons of mass destruction"
And of course, anything that fires any of the above (including rimfire) is a "military-grade automatic sniper/assault rifle"...
That is why switching from the M-14 to the M-16 was problematic in Viet Nam. A 55-grain bullet is no brush buster like the “.30-06 Short” 7.62 NATO, one of the secondary reasons the 5.56 NATO is not suitable for deer.
