There is also a fallacy in this conversation that any of us can predict the future. The civilian and hunting market can/will move with some predictability but if there was a massive war, and subsequent arms race, that might very well change the landscape of what we shoot and what is cheap and widely available.
A few folks here are getting wrapped around the axle on small details that hardly matter to most hunters.
Everyone of these calibers has a successful track record, hence their mention. Nobody is mentioning .303 british or .220 swift or any of the other calibers that have fallen to history. To me, this signifies the fickle nature of the market and unpredicability of advancement.
I love a vigorous debate and it truly is a lost art in society, but it needs to be objective and polite.
Thirty years is a long time and there is a lot to consider.
