Of course every round ever made has its application, to the shooter of course. The 06 though developed for the military is now the most popular hunting caliber of all time. The military gave it up because others found what they though as a better cartridge, different people, new cartridge.
So our military no longer uses it, so the people who run things don't see it as the best, the writer is correct, but where was the .223 in 1906? More new development.
The 06 did have its use, and still does though not in the military.
So was it a mistake? Not at all, they knew what they were doing, and just moved on from there. Change always happens.
Was it the best choice? To those people at the time, but not now. The 06 is one of the best bolt rifle cartridges ever designed, for a bolt action. Get something else for for machines guns, and yet another for snipers, and yet another for hand guns, there is no all around cartridge for everything.
Calling the 06 a mistake is idiocy. You just have to realize that no one round will take care of every application. Thinking that you can have a light carry machine gun and a sniper rifle in one is once again stupid.
Is this same writer saying that the 416 Barret is a failure because you can't shoot it out of an M-16 action?
Why the author is right that its a failure:
Nope, the 06 won't shoot as fast and carry as light as a .223.
Nope, the 06 won't shoot as far accurately and carry as much energy as a .416 barret.
Why he is wrong:
It's not a .223, it's not a .416 - it's an 06; and in my experience for my purposes, that is one bad round.
