As usual, the neophytes want to own the language. A .223 would fit the military definition of "medium-energy", along with the Russian "short .30" used in AK-47s. "High-power" begins with something like a .30-'06 and goes up to a rhino-killer like a .416 Rigby. Some military snipers use a .50 BMG round. I don't know what you would call that.
I have a hand-me-down Winchester model 1886 chambered in .45-70 Government. The round is about the size and shape of the huge Crayola crayons we used to have in school, larger than your finger. Everybody moans about the .223 being a deadly cartridge. The .45-70 was used to take down bison and grizzly bears.
