And it doesn't need to be.
"Well here we are in a new decade, which seems to be marked by some outstanding numerals! Take for example 1906, the date year of the landmark cartridge of our time. The 1906 cartridge, which was a modification of the 1903 cartridge previously standard, is as near perfect as things of that sort can get. It is amusing (and slightly annoying) to see how the purchasers of sporting rifles seem to think that improved cartridge design is the answer to everything. I have long taught that if you can't do it with a 30-06, you probably can't do it. Every time some new brass powder bottle appears for sale, all sorts of people, qualified or otherwise, leap into the breach to explain how this new round is somehow better than what has gone before. Whether it is better or not must depend upon what it is designed to do, and it is effectively impossible to say that a shooter accomplished his purpose in the field with the new cartridge in a way that he could not have done with a 30-06. As it is said in Lindy Wisdom's verse: "There ain't many troubles that a man can't fix with seven hundred dollars and a thirty ought six." We do not know about the $700, but we do have confidence in the great 30-06 cartridge...........the winner and still king - the 30-06."
